Having a healthy synapse is important for learning and memory, sensory perception and brain function.

A synapse is made up of presynaptic and postsynaptic terminals. The post synaptic neuron integrates all the signals it gets and tells what to do.

This is a reason why the brain has wrinkles and folds to fit as many neurons as possible.

Since the sodium channels are closed does that mean the potassium channels are open?

During depolarization the sodium channels are open and during repolarization the potassium channels are open.

That is very interesting that dendrites have have different parts of them that have different functions thats i did not know about. The receptor sites receive molecules of neurotransmitter. Dendritic spines are part of the connections between neurons.

This is very interesting that the endocrine system has many different glands that produce different hormones and each hormone has a specific job.

When talking about the PNS it was very easy to remember the two major systems. Somatic was things that you can tell your body too like for example grab water and autonomic is when the body monitors itself like when it gets hot we don't tell our body to sweat it automatically does that.

The brain has a lot of neurons around 86 billion! As you can see the brain has many folds and these folds are called the gyrus. The reasoning behind the gyrus is because these folds give the brain more surface area to fit more neurons in the skull and also enable higher functions.

The telencephalon is the largest portion of the brain in which this portions main function is speech and language. The diencephalon function is to release hormones and is also a processing center for sensory information and autonomic control.

The csf is a protective measure for the brain that is able to absorb shock. Every day the human body produces about 500ml of csf a day.

Neurons are a very complicated and interesting part of our body's. One thing about neurons that sticks with me the most is action potential which I learned heavily in my physiology class. Action potential is basically a quick electrical pulse that happens when a neuron sends a signal.

Being able to figure out what the epigenome does and how it works will be able to tell us how the different cells work but also how our environment can change our genes.

This is a very interesting study that shows giving a newborn the physical touch it needs may improve better moods and less stress.

The nature vs nurture will be a forever debate but I think that both genetics and environment play a significant role in how person turns out to be.

I believe that physically genetics explains the most but behavioral traits I believe mostly come from someone's environment.

I have noticed that living in the United States people view status through individual accomplishments rather than contributing to a group.

It is quite surprising how much humans have adapted to the world over time from finding a way to create fire to now have self driving cars.

Is the EEG only used to study sleep or what other situation would an EEG be used?

This is a very interesting fact to know. I did not know that using an EEG and MEG can see different processing times in children with ASD and children without ASD.

This type of non invasive technique is used for people that have major depression.

The MRI is such a powerful machine but there are some flaws to it. You are in a loud and confined tube for multiple minutes. This may be great for patients that are able to do this but must be difficult to have a child or someone in general that does not feel comfortable doing the scan.

There are two questions being asked in this sentence. Since there are two questions and different techniques, which are the best techniques to answer these questions?

For many of years people had different beliefs of where the mind was many believing it was the heart. Until one of the first people to say it was in the brain was Hippocrates. As time went on we were able to prove that this is where the mind resides.

Being able to use brain imaging has been such an important part of helping people out. In the medical field having the ability to take a picture of your brain and help diagnose any problems that they're might be is great. It is great way to help understand how the brain functions normally compared to when a brain does not function correctly.

I have heard of this famous story about Gage. It is crazy to think that damage to his frontal lobe caused him to change his personality and yet years later he became his old self. The way the body heals itself is crazy because I believe it is hard to explain how someone's mind became so angry after a horrific accident and yet years later he goes back to being calm.

It is truly amazing how complicated and mysterious the brain is. There have been many divisions of psychobiology that have been discovered throughout time to help us understand the brain. The more advanced people and technology become the more I believe that there will be more divisions made.

I am extremely confused on this whole concept in section 1.1.5. I was wondering if anyone had a website link or video explaining this more clearly?

I understand that there are certain areas of the brain that are effected differently when damaged. When there is damage to the brain can the brain be healed back to normal or is the damage irreversible?
