There was a time when philosophers contemplated the true meaning of the brain and thought it of little importance, irrelevant to our mental being. This is a very huge difference from our current understanding of the brain as the most complex structure in the known universe. Much research has been done and is still in process in an attempt to realize the entirety of the brain and everything it is connected with.
The brain is interwoven in our every second waking being, everything we do our brain is a part of, no matter how small the movement or thought. The brain is split up into two different hemispheres, the left and the right. These different sides control different things, where the left hemisphere controls fine tuned language skills and actions, the right side controls coarse language skills and visuospatial skills (such as face perception and perceptual grouping). I found it very interesting how in depth and captivating our brain truly is, with all of the different functions and roles it offers.
