Its something we learned about very early on in the class, but has really stuck with me throughout the semester. The concept of brain plasticity, the ability of our brain to make physiological changes throughout life in reaction to changes in anything from environment to behavior. This concept is somewhat mind blowing to me, because its well known that humans are the most adaptable species on the planet, with the ability to live just about in any climate the earth has to offer, through the computing power of our brains. If thats not extraordinary enough, our brains themselves change and adapt to external changes just like the humans as a whole. Also, being a freshman in college, the concept is particularly potent because if you think about it, our brain is going through an obscene amount of adaption as we transition to a collegiate level of education. Its interesting to think of how as we learn in school, our brain is in-fact in a sense learning as well, about the environments and styles of thinking that we must use to survive college life. Because of its relevance throughout the human life and development, i'm guessing if any topic we learned about was to stick with me for a number of years, it would be this one.
