Depression in the Brain and What’s Being Done About It

August 30, 2014

Depression isn’t just being sad. It is often a chronic condition and it sometimes claims the lives of the people that it affects. Many people with depression struggle with going to seek help but those that do often find that the treatment may not work for them. Some of the treatment for chronic depression are therapy and medication. Some people with a severe variant of the condition may also choose electroshock therapy after being assessed by their neurologist and psychiatrist. Unfortunately, there is still a small subset of people that do not respond to even this treatment.

It is now more important than ever to understand how depression works.

People who are depressed often have a ventromedial cortex that is up to 40% smaller than those without depression. It’s no surprise, really. The ventromedial cortex is a bit like an emotional control system and when someone is suffering from chronic depression, it becomes nearly inactive during the depressive phase and hyperactive during the manic phase. There are other parts of the brain that both decrease and increase in activity when someone is suffering from depression.

Since scientists have a better understanding of how depression work, there are some new methods to treat it being developed.

According to an article by CNN medical correspondent Dr. Sanjay Gupta, a researcher at Emery University is looking for a way to help those patients that don’t seem to respond to the treatment that is available to them. Dr. Helen Mayberg has worked on mapping the depression circuit and noticed patterns that indicated that there is a small part of the brain. They called this Area 25. Dr. Mayberg noted that when area 25 turned up, it was correlated with how sad someone was. At the same time, while area 25 turned down, the rest of the brain turned down, and that indicated that people would find it much more difficult to pay attention and do other tasks.

What is the new treatment?

Electrodes get implanted in the patient’s brain. These electrodes get power from a battery pack that is also installed under the patient’s skin. A patient doesn’t need to be put to sleep for the surgery because a brain cannot feel pain – after all, it has no nerve endings. After that, an electrical current is sent to the brain. Over 75% of the patients Dr. Helen Mayberg has treated have gotten and remain better, with one caveat. If the battery under their skin runs out, the depression returns.

It’s still early days, but this study could indicate how we are going to deal with treating people who suffer from this condition in the future.

Why Do I Yawn?

August 30, 2014

You wake up in the morning. You stretch and yawn. You are tired at work, so you yawn. You are scratching your ear and yawn. You are working on your research project and yawn. You are watching a movie where someone yawns, so you yawn. You can’t escape yawning. You do it all the time. In fact, if you are an impressionable person, you may have just done it right then. I know just thinking about yawning makes me want to yawn. When having an important conversation, you may feel like yawning – or, horror, in a job interview. It’s incredibly difficult to suppress a yawn. Don’t feel bad, though, everyone does it.

Why? Why do you yawn?

There are lots of situations in which you feel like yawning, but what exactly is it doing to your body? Why do you have to yawn when someone next to you yawns on the bus?

Well, we are still not that sure. Yawning is contagious and we do it all the time, which is why some scientists think it may have been a primitive form of communication between each other.

Another theory is that yawning helps cool the brain. A study may indicate that people who are hot tend to yawn a lot more than those who aren’t. In the study, 48% of the subjects yawned, but when they held a cold compress over their head, only 9% did. However, the study did not go on to measure the actual temperature of the brain. For that reason, the cooling down theory is still a big question mark in the scientific community.

As far as why we yawn, we are still not sure. There are lots of theories, but not one that has been proven close to conclusive yet.

Scientists are still performing studies and reading through the literature – doubtlessly holding back a couple of yawns themselves.

The Color Red

August 30, 2014

There is some science being done about the color red. It isn’t just the color of pretty backless cocktail dresses, fast cars or satin bed sheets. Red isn’t just a seductive color, it is also a manipulative color, according to an article by David Robson on the BBC Future site.

Red may have been seen as a warning color by our ancestors.

After all, red is the color of our blood. The color red may still have a bit of an influence on our moods, desires and the way we act. That’s why there is a new branch of psychology that is still in its infancy, called color psychology. Of course not all of their research is focused on the color red, but it certainly stands out among other colors. After all, humans are some of the only mammals that can distinguish between the color red and the color green, for instance.

Studies have shown that competitors wearing red tend to win more than those who are wearing blue. Scientists aren’t exactly sure whether this is because red is a more dominant color and the person wearing it has an increased heart rate and is more motivated or if they intimidated the opposition. Competitors who wore the color red were usually favored by professional referees, too.

Both men and women are seen as more attractive when they are wearing red, but it may also come off as aggressive, depending on the shade of red.

What we need to keep in mind is that the science is still very young. There is an indication that red could make a difference, but we are still not entirely sure how – or even what that difference is. That is one of the reasons we are so far away from being able to paint our office in productive colors, though wearing a red tie to a job interview would certainly not hurt.

Yes, Working Out Does Help Your Brain

August 29, 2014

You already work out and try to eat healthy. You know that eating healthy and working out makes you look younger, helps your skin and keeps your weight down. You do it not just for the way you look, you know that having a very sedentary lifestyle can be detrimental, especially as you get older.

Your brain needs to be exercised to. You are always using your brain. You may choose to exercise your brain by doing things like sudoku and doing creative things. You exercise your brain by learning instruments or writing stories. You can’t forget that you also exercise your brain by actually exercising.

Your brain is an organ that lives inside your body, and working out certainly affects your brain.

How does exercise affect your brain?

Doing cardio is great for your heart, your body and your brain. Even just exercising for a brief time may actually affect how your brain processes information and how your memory functions. Getting your heart pumping and your blood flowing means that your brain function improves considerably.

Your cognitive performance doesn’t just improve while you are exercising, but there are some studies that may indicate that your brain and cognitive function increases across your entire life as you exercise. You can even improve your brain health by doing some limited exercising when you are older, which can help slow down some natural decreasing of the brain.

You probably already know that exercise helps you unwind, but it also protects you from future anxiety and stress, so if you are feeling frazzled, the gym is always a good bet. Since exercise produces endorphins, you can be sure that if you are a bit sad you’ll feel better after a run on the treadmill, but there is some indication that it also helps alleviate depression.

You need to exercise to look after your body. Just don’t forget that exercising also helps your brain.

Your Insomniac Brain May Be Different Than Others

August 29, 2014

Insomnia is not just a problem that happens at night. According to researchers, insomnia is tied to different brain activities – and those that suffer from this sleeping difficulty may also have different brain activity at all times of the day.

In fact, according to Rachel E. Salas, M.D insomnia is not a nighttime disorder at all, rather it is a 24-hour a day condition. According to the results of the study, people who have insomnia tend to have more alert. Originally, Salas thought that people who sleep soundly would have more alert brains with more plasticity, but it turns out that she was wrong.

People with insomnia have a motor cortex that is more adaptable to change than those who sleep well. The neurons in the same region of the brain were more excited with those with chronic insomnia than with those who didn’t have it.

This could mean that people who have insomnia are in a heightened state of awareness and this could be what interferes with their sleep.

Your overactive brain may be hyper aroused and you could find that you are as alert at four in the morning as you are at four in the afternoon.

So what came first?

Researchers are still not sure. The study wasn’t designed to find that out, so we are still not sure whether people who suffer from chronic insomnia have more active brains or if not getting enough sleep will leave you in a state of hyperarousal. The study did show that if you give both good sleepers and insomniacs an easy task, they will perform at approximately the same level. However, when they are presented with more complex tasks, insomniacs have a harder time completing with them.

There are different types of insomnia and they are usually tied to different things. The best way to treat it is by taking care of any underlying problems and practicing good sleep hygiene. If chronic insomnia is bothering you, you should place a call to the doctor.

Your Frontal Lobes After a Traumatic Injury

August 29, 2014

How your brain is affected after a traumatic injury obviously depends on what the injury is. It may also have to do with where the impact was and what exactly happened. The brain has many parts and each of them do something a little bit different.

While the study of neuroscience dates back to ancient Egypt, the study of the nervous system the way we understand it now has increased dramatically, especially in the last part of the twentieth century. The way researchers approach neuroscience in modernity is one that is interdisciplinary and collaborates with fields like chemistry, mathematics, linguistics, psychology and philosophy, among many others. This is important because neuroscience – or neurobiology – is how we understand the brain and although we understand quite a bit, we still also have a lot left to understand.

Here’s what we know about the frontal lobes.

The frontal lobe is one of the four major lobes in the brain of mammals and it’s, well, in the front. Your frontal lobe is in charge of your consciousness, so injuring it is a really big deal. It’s also in charge of how you respond to you environment, including your emotional responses. It choose between things that are good and bad and plays a big role in decision making. It makes sure that you don’t do anything socially unacceptable and it links up how things are similar to each other.

An injured frontal lobe can lead to paralysis, which can be in any body part, an inability to do things that are complex in an order (like getting ready to go out in the morning), getting stuck with one particular thought, not being able to focus on a particular task, having mood swings and changes in both your personality and your social behavior.

Luckily frontal lobe injuries aren’t that common and only occur after a bad car accident, a fall or a gunshot. Treatment can eventually help a patient regain some amount of the prior functioning along with strengthening skills to compensate for those that are lost or diminished.

Would you become ‘Lucy’ if you could use 100% of your brain?

August 28, 2014

The premise behind the blockbuster Summer movie Lucy is simple and a little out there.

What if we could use more than 10% of our brains?

Would you become telepathic, suddenly be able to read other languages and choose not to feel pain? Lucy can.

The problem is that the brain doesn’t really work like that. Think of your brain as a finely-tuned piano. On the piano, if you press down one key, then another, then another, you start making a melody. Your neurons are what allows for this to happen – pressing all keys at once would not sound very nice, right?

Your brain is like a really complex instrument.

There are lots of things that your brain is doing at one time. While you are reading this article, your brain is also in charge of your breathing, of the way that your hair feels on your skin, of telling you how hungry, upset, calm or curious you are. Your brain is doing lots of things at the same time at all times, even when you are sleeping.

Most of your brain is active all the time. You probably don’t use the same part of the brain to work out as you do to loaf around on the couch and watch Netflix, but generally you have used all of your brain after a twenty four hour period. More complex task take more effort from the brain and therefore use more parts at the same time – writing a story, painting a painting or learning to drive, for instance, are all very complex tasks that make your brain work hard.

How do we know that we use more than 10% of the brain?

You don’t have to take my word for it. Unfortunately, some people who have suffered head trauma or brain injuries stop being able to do certain things. If you only used 10% of your brain and you hit the front of your head, then how could it possibly affect you when you still have the 90% bit of unused brain leftover?

Another one is how your brain works. The myth of the 10% indicates that everything is one single mass and everything takes place in one part of the brain or the other. This is a misunderstanding of how the brain works. There are distinct regions in the brain that are there to process certain types of information, and communicate between each other. We don’t really understand the brain that much yet, but from what we do know, it’s enormously complex – like a super highway in your head.

The brain is also incredibly taxing. Did you know that your brain takes way more oxygen and nutrients to function than any of your other organs? It’s 2% of your body weight and it still needs that much. By this point, if this was unnecessary, we would probably all have smaller brains.

Lastly, there have been brain scans that show that your brain is always active. There is never a part of the brain that isn’t functioning at all.

You already use 100% of your brain. Unfortunately, you won’t ever be able to read a different language if you don’t learn how to first, and you probably won’t harness the power of telekinesis.

How Does Your Brain Make Decisions?

You make so many decisions a day, it’s kind of crazy. You make the decision of what to eat for lunch, for instance. You…

You make so many decisions a day, it’s kind of crazy. You make the decision of what to eat for lunch, for instance. You make the decision of which cereal to buy at the store. You make the decision to merge into the right lane or stay in the lane you are in. You make the decision to clip your nails, or you make the decision to grow them out a little further. You make the decision to make your partner coffee while you are making your own. Every single day of your life is comprised of a thousand little decisions that add up to something.

The thing is, you probably only think about decisions when you wonder if you are making the right one.

Am I making the right choice?

Is this the right car for me?

Should I rent this apartment?

Should I ask that cute barista out?

You eventually come to a decision, and it can be wrong, or it can be right. There is no guarantee that whatever decision you come to will lead to the outcome that you want. If the barista turns you down, you’ll be embarassed but probably survive. If you rent an apartment in that side of town, your children may end up going to that school district. Some decisions are a way bigger deal than other ones and our ancestors have been making them for a really, really long time. Your brain tries really hard to make the right decision for you – sometimes, it’s wrong, and sometimes, it’s right.

How does your brain make that decision?

Our understanding of choice is a little bit limited. We know that emotions have a great deal to do with our choices, but while emotions and logic are the primary decision makers in your brain, they aren’t the only ones. I’ve agonized whether my choice is the right one even when it comes to something as insignificant as a bellpepper. It’s a bell pepper in a shop; of course it’s going to be up to standard. That’s not what is going through my head, though.

I’m thinking:

Oh, wow. This looks a bit beaten up. That one looks a bit small, though. This one is organic – but it’s so much more expensive.

And on, and on, and on.

Surprisingly, I’m nothing like that when it comes to a big purchase. I know instantly if this is the expensive dress I want to buy for the party once I’ve tried it on and as soon as I walked into my apartment, I knew I would have to rent it. My husband is way more decisive about small things and way more indecisive about big ones.

Scientists are still trying to understand exactly how people make decisions. Talking exactly about how humans make decisions is very complicated – in fact, there’s a whole new field that scientists call “decision neuroscience” to study this.

Where your decision is made in the brain seems to vary depending on the type of decision it is. I don’t mean like the difference between buying your first new car and deciding to eat grapes over apples, but rather the decision you make when you decide “Oh, I should wash the dishes” and the decision you make when you think about how, exactly, you are going to wash the dishes. The first is an abstract concept and the second one is a concrete concept. Your brain is always calculating the risk & reward regarding something before you make the decision. Experiments done in monkeys indicate that scientists can actually predict what decision they are going to make before they have made it themselves.

Let’s say that there are two parts of your brain.

One is your intuitive part. One is your logical part.

Your logical part is really slow. It’s lazy. You can’t use it while doing something else. If someone asks you to do a complex equation while you are driving, you are probably going to pull over and write it out before you arrive at a conclusion.

You use both of these parts of your brain when you make decisions.

The problem is using the right part at the right time – using the intuitive part of your brain when you need to use the logical part. We’ll just have to continue to make the decision to keep studying our brains until we know what is happening for sure.

What is a Nootropic?

August 14, 2014

Nootropics, also referred to as smart drugs, memory enhancers, neuro enhancers, cognitive enhancers, and intelligence enhancers, are drugs, supplements, nutraceuticals, and functional foods that improve mental functions such as cognition, memory, intelligence,motivation, attention, and concentration.

Nootropics, also referred to as smart drugs, memory enhancers, neuro enhancers, cognitive enhancers, and intelligence enhancers, are drugs, supplements, nutraceuticals, and functional foods that improve mental functions such as cognition, memory, intelligence,motivation, attention, and concentration.

Originally in order to be considered nootropic a compound would need to:

  • Enhance learning
  • Resist impairing agents
  • Facilitate interhemispheric transfers of information
  • Enhance resistance to brain “aggressions”
  • Increase tonic, cortico-subcortical “control”
  • Not have the usual pharmacological effects of neuro psychotropic drugs. ref

Since then “nootropics” has gradually expanded to either be synonymous withcognitive enhancers or refer to the subset of non-stimulant cognitive enhancing compounds with very few side effects and low toxicity.

A cognitive enhancer is defined by its ability to augment performance on one or more cognitive measures.

Scientists Unlock “Brain Pill” But Will It Be Banned?

August 7, 2014

Welcome To The Future

A new advanced brain supplement is sending shock-waves through the medical community. Major pharmacy companies are scrambling because they have zero control over this “Un-regulated Brain Booster”. It’s called Evo™, and the results are so amazing… they’re almost unbelievable.

The memory-enhancing formula is already generating controversy, but it’s not what you may think. Evo™ uses a simple secret to revive your brains memories. It’s a highly-concentrated blend of 100% non-pharmacological ingredients, available right over the counter. Some of these ingredients, like bee pollen for example, have had their ability to rejuvenate and heal the mind praised for centuries. Other key ingredients have only come to light very recently; the result of half a century’s study of the brain.

Evo on TV

Are humans the smartest we’ve ever been? – Dr. David Billinger, a neuroscientist at Harvard Medical school says “A large portion of the worlds population may be suffering from mental fatigue and a loss of IQ due to circumstances from our childhood.“ What are these circumstances? To put it simply; enviromental toxins. “We have been ingesting these pesticides for years and its damaged our brains,” says Dr. Billinger. According to the study, even if people are living healthier lives today, we are combating years of abuse on the brain. “Brain health is something most of us overlook and now science is telling us to pay attention.”

100% NATURAL – that’s good, right? Yes, if you’re looking for a healthy way to increase your cognitive abilities. No surprise ‘Big Pharma’ seems to feel threatened by this breakthrough in brain health. Particularly as Alzheimers and Dementia are poised to become the biggest killer of baby-boomers over the next 10 years. These pharma companies are scrambling to put a stop to it before the public catches on and it costs them BILLIONS. Why is this tiny pill protected from legislation? Simply put, it’s absurd to make vitamins, minerals, or bee pollen illegal. That means as of right now, anyone can indulge in this brain supplement without a prescription or hefty price tag.

Critics say the problem is – everyone wants to have a better brain, and improve their memory, so it’s only a matter of time before this pill starts getting abused by students who are looking for an extra edge or people in demanding jobs. While abuse of any supplement is nothing to joke about, I think having several more “brainiacs” or Albert Einsteins around is the last thing we have to worry about.
