Brain and Behavior

In this chapter the main topic is about the brain and how it develops and how it has been researched for many years. The ted talk I liked was by scientist Miguel Nicolelis. He built the brain-controlled exoskeleton that allowed a paralyzed man to kick the first ball of the 2014 World Cup. How can someone build a vest that transmits the motion from your brain to parts of your body that is paralyzed? Miguel Nicolelis did just that. So, basically he put this exoskeleton together, 15 degrees of freedom, hydraulic machine that can be commanded by brain signals recorded by a non-invasive technology called electroencephalography that can basically allow the patient to imagine the movements and send his commands to the controls, the motors, and get it done. This exoskeleton was covered with an artificial skin invented by Gordon Cheng.

The research that has been done has helped us take huge strides in helping us understand the brain and how it functions. Things that we have learned include the frontal lobes are the center of rational thinking and of self control. It is also understood that neurotransmitters, or brain chemicals, are responsible for our moods and of the general state that we are in. It is also known that severe mental illnesses, such as Schizophrenia and Bipolar Disorder, are diseases of the brain. Lesions or damage to the frontal lobes and to other parts of the brain can and affect impulses and impulsive behaviors.

    The reasons you have listed about the frontal lobe damage is why concussions are so dangerous to this part of the brain. I have a son who has some behavior issues and so researching the neurotransmitters has always been very interesting too me.

Final post

Ending my first year as a college student was interesting. But even with that said I learned a lot about psychology. From this semester I learned how the brain works and psychological disorders. Our first lesson was over brain and behavior. In a Ted talk a scientist talked about how the brain works. I found it interesting that a neuroscientist helped design a exoskeleton suit that helped a paralyzed man kick the first ball at the 2014 World Cup. I also learned about sensation. This involved our 5 senses that we use to be aware of our surroundings and adapt to what is happening. In week 5 we learned about a development of a child. The biggest thing that stuck out to me was the nature vs nurture debate. After that lesson we learned about memory and learning. The studying of memory has blown scientist minds away when they study and look at the brain. Scientist have studied how we receive information and translate that into our memory bank. In module 5 we learned about motivations and em...

Gratitude Visit

I wrote a letter to my youth ministers that are leaving the church that I grew up at and taught me all the years I was in the youth group. Here is the letter. Dear John and Crysty,      There are not enough thank you's I could say to the both of y'all for how much y'all did for me and the others in the youth group as I grew up. I still remember my first Sunday class I ever had in the youth group. John made me stand up and say my name and who was my favorite super hero and of course I was going to say Batman because I knew who was asking me the question. Some of my favorite memories growing up were from youth group events. From Pine Springs, The Houston Mission trip, or even Guatemala. I am still so thankful that I got to experience Guatemala and it wouldn't have been without John and my Dad basically forcing me to go. I learned so many lessons from that trip that I still think about as I write this letter to y'all.      I want to say thank you ...
