Brain Studies: EEG

I was first introduced to the ways the brain can be studied about 6 months ago when my boyfriend, Anthony, had to get a 48-hour electroencephalogram (EEG).  The reason for getting an EEG: he’s been diagnosed with post concussion syndrome.  It sure has not been an easy ride for him.   It’s been over a year that he has been experiencing the symptoms of post concussion syndrome such as fatigue, dizziness, anxiety, insomnia, and occasionally blacking out.  It definitely has not been easy for me either.  I know all I can do is be here for him.  He says I make him feel better, but I always wish I could do more.

This past summer, his doctors decided that an EEG would help give them a better understanding of the damage that was done to his brain from the initial concussion, which happened in July of 2012.

The EEG was to look at his brain waves.  An EEG records the electrical activity of the cortex just below the skull using a device called an electroencephalograph.  When getting an EEG, you have sponge-like electrodes placed directly on the scalp, and a special solution to help conduct the electrical signals from the cortex just below.  These electrodes are connected to an amplifier and then to a computer to view the information.  The results form waves that indicate many things. (Ciccarelli 67)  Unfortunately, the doctors reported that Anthony’s results had some “weird” brain waves.

So I got to experience what an EEG test looks like first hand.  Since his test was 48 hours, he was given the option to have the majority of the test done at home.  The doctors used a jelly like substance to stick the electrodes to his scalp, and then wrapped up his entire head, not including his face, in some kind of medical bandage, just to keep the electrodes from sliding out of place.  They gave him the amplifier, which was connected to the electrodes in a little pouch with a strap that he had to wear around like a satchel.  When I first went to see him once he got back from the doctors, it was certainly weird to see him all wrapped up with wires coming out of his head.

Since then, he still goes back to the doctors occasionally, but he hasn’t had any major tests done like the EEG.  Before he got the EEG, I had never heard of the test.  I had no prior knowledge of ways that we can examine the brain.  Learning about all the different ways that the brain can be studied has been especially interesting to me, because of what Anthony has gone through with his concussion and post concussion syndrome.

Neurons and Traumatic Brain Injury

neuronsDuring the first part of class, we discussed the importance of neurons in psychology and the direct relationship between psychology and biology. About 100 billion neurons make up the body’s information system and there are about 100 trillion connections between them. These neurons do not only control biological aspects of one’s body but also affect behavior. Everything we do or think begins as an action by neurons in our brains. Since psychology and biology are so closely related, action or inaction by neurons in the brain can have far-reaching effects on other parts of the body.

A family friend experienced this firsthand. When he was in college, he was sitting on a milk crate in the back of his friend’s van on the way home from a party. Not far from campus, the van struck a tree and, since he was not wearing a seatbelt, our friend was thrown from the vehicle. He suffered a traumatic head injury. My dad drove to visit him right after the accident. Our friend could not speak, eat or perform normal daily functions on his own. My dad and mom, who visited our friend later when he was in rehab, both said it was as if their friend was a child trapped in the body of a 21-year-old.

This change occurred because traumatic brain injury directly affects neurons and can even kill them and the connections between them. Since neurons all work together, these losses can have devastating effects on many areas, since biology and psychology are linked. Different neurons have different functions and control different areas of the body and brain. When our friend experienced head trauma, the neurons for certain functions, such as speech and memory, were negatively affected. He lost the ability to control these parts of his body because the neurons stopped firing and sending information to the brain and other necessary areas.

Fortunately, he eventually made a full recovery after lots of therapy and rehab. This experience epitomizes the link between neuropsychology and biology and shows the importance for all neurons to be working properly. Neurons control everything we do and without some functioning properly, the results can be devastating.
