A Portrait of the Brain
Through Theories and Discussion
A hemispherectomy is a surgical process in which the brain of a patient is halved and one of these parts is then removed. The procedure is only ever carried out on individuals who are very young, as their brains are still flexible, pliable enough that the remaining portion will then take on the functions of the half that had been removed. Though this process is rather rare, only carried out when the child in question is experiences dramatic seizures that can only be halted in this way, it brings a crucial element to the table, far beyond the medical benefit for one. Hemispherectomies prove that patients can survive with only half of the brain, and thus, if the single mind could be partitioned into two separate bodies, producing a pair of similar living organisms - which patient would be the original? This very question has basis in the complex phenomena known as consciousness.
Human consciousness can be rather elusive to define, as there are differing theories as well as opinions as to what the state is as a whole, and what it can then be boiled down into. Morgan Kelly (2014) claims that most people consider consciousness to be the complete, “non-physical mental package” that composes an individual, such as the personality, memory, experiences, and notably, emotion. Awareness, then, is also taken to be more focuses, as in the specific items noted in the conscious. Scientists who study consciousness hold the belief that if an explanation can be reached on how the brain becomes aware of something, the larger phenomenon of consciousness can likewise be explained. According to Kendra Cherry (2013) the functioning definition of this awareness from a psychological standpoint simply is the reference to being aware of sensations, thoughts, and other internal processes. Thus, in most scientific theories, consciousness emerges from the physical functions of the brain, and thus most researches therefore look for the the physical mechanisms in the brain that might generate this non-physical awareness.
Anil Seth (2012) argues that though the brain contains about ninety billion neurons, and about a thousand times that in connections, consciousness isn’t just about these neurons, these physical stimuli. The human conscious is about the self, as all the experiences that our minds recall are tied to the experiencing self, the “I behind the eyes.” The complexity of the “selfhood” emcompasses the first-person perspective concerning the world, a sense of ownership of the body, actions, thoughts and perceptions of the internal physiological condition, as well as the very shape of individual reality. This includes that narration of past experiences and imagined futures.
Despite the debate of the primary roots of the conscious, as well as the proclaimed importance of these differing levels of research and their chosen direction, it is without doubt that the study of the...
