If I were to design the brain differently, I would just generally enhance some of the advanced and valuable but intricate structures of the brain to render humans more adaptive of their physical and social environment.
First, I would upgrade the visual system of the human brain. Vision is important because it helps us to see objects and events around us and to perceive these things in multiple ways such as color, size, shape, and its other details (Faye, 2008). I will specifically upgrade the primary visual cortex that is responsible for the conscious processing of visual input and will also enhance the function of the superior colliculus in the midbrain as processors of reflexive visual input. Not only that but also I would expand the associative cortical regions in the parietal and frontal lobe. These specific parts can integrate multiple inputs thus providing people with an adaptive mechanism of vision (Toga, 2008).
Second, I will enhance the ascending reticular activating system of the brain. I will probably lengthen and widen this net-like formation of nuclei that runs up the brain stem. It is because of the vital functions of this structure that it deserves an enhancement, a greater size for greater efficiency. This specialized part of the brain stem controls metabolic processes like respiration, cardiovascular function and digestion. Upgrade of this structure is also essential for man’s further adaptation through increased regulation of a person’s level of alertness and patterns of sleep (Toga, 2008).
Last, but certainly not the least, I will enrich the parts responsible for the memory skills of the brain. Memory is significant to humans because it serves as the stored information of essentially all of our daily activities. It gives us access to past experiences, as well as, grants us language comprehension, facial recognition and skills mastery (Roediger, 2008). The short-term memory is thought to be located in the deep temporal lobe while long-term memory is probably between the medial temporal lobe, cortical regions, and the midbrain (Toga, 2008).
