The Cortex

While I was reading through the textbook one thing that i came across that really amazed me was the cortex. The cortex is the part of the brain that controls our senses and movements. The motor cortex, located towards the back part of the frontal lobe, causes us to move our muscles. Just like the motor cortex sends messages out, the sensory cortex, located parallel and directly behind the motor cortex. receives messages. The sensory cortex controls the sense of feeling. The visual cortex, located on lower part of the occipital lobe, controls the sense of sight. Finally, the auditory cortex, controls the sense of hearing.
There are two things that I found really interesting about all of this. The first is that the left hemisphere of the brain is related to right side of the body and vice versa. This means that either side of the brain controls the opposite side of the body. The second thing I found interesting is that all of these cortexes, which cause every one of our movements and senses, only take up one fourth of the brain.  This just shows how much more there is left to learn about the brain.
