The Individualized Brain
The brain, as does any organ or cell, is dictated by our preexisting genes that not only play a role in the initial devising of our various lobes but they also implant intrinsic genetic code, whose effect determines our demeanor and our various qualities in adolescence and beyond. Here is also where our environment plays a role, in which our assumed repository of tendencies is perturbed by our external world. Logically speaking, no two individuals (twins being a meager-ish exception) have the exact same genetic dispositions, nor do any two individuals go through the same alliterated life, the equivalent of our "environment". This being said it is deductible to assume that no two individual's brains would be the same either. In any moment of our lives, ,whether we are conscious and full of alacrity or acting subconsciously and inadvertently, our dispositions influence how we react, adapt, conflate, and respond; whether we are can accept that or not. Now I am no neuro-scientist (yet) but I can convey this with the utmost certainty, the attest being the fact that we are all individuals with different opinions, different aspirations, different aesthetic, different levels of sagacity, and above all different calibers of desires. Everything from our emotional pretenses, or portion of the brain that includes the thalamus, hippocampus, hypothalamus, various hormonal glands, amygdala, epithalamus, and various others, to our more intellectually-dependent, contrived areas including the frontal lobe and its constituents, are variegated immensely from person to person as one's experiences and genes converge. But what about the universal functions that enable us to actually stay alive for more than ten seconds and that constitutes a subtle displayment of relation? Well lets read on shall we?
The Universal Brain(?)
Alright so so far we really have been elaborating and arduously discussing layers of our fundamental workings that exhibit behaviors fairly unique to humans and humans alone. Yet what about the section of our brain that allows us to actually relate ourselves to the more primordial and "under-developed" species such as the chimpanzee (not the most prime example as we have found correlations in emotional responses ) or the humming bird? Apart from actually having established and routed goals that ultimately have the same outcome of acquiring sustenance we have another extreme relation, that both of our brains have mechanisms designed chiefly to maintain a level of homeostasis and to regulate our breathing and other autonomic faculties such as fight or flight. It is truly humbling and an attribute of modesty to consider the fact that we and animals really aren't that copiously apart on the spectral chain as speculated by many people. Yes we do have very significant differences that essentially and superficially allow us to gloat (intellectual competence in the form of reasoning and logic) but honestly that really protrudes in our life and is repented in our lives. In all circumstances, [and this is very subjective] the true meaning of existence biologically speaking is to prolong the amount of time that we can as a species can acclimate on this Earth. I'm not saying that being intellectually superior isn't advantageous, of course it is and in all parities I advocate intellectually-dependent ventures, that is really what science is. It would be silly to be so narrow-minded as to say that we have no significant differences between us and animals that actually has some precedence or weight. I am saying that we have greater similarities between us and animals that many people deem we don't. Actually a few days ago I was reading an article in which experiments were done on a few voluntarily present human subjects who were deprived of their fundamental Maslow's Hierarchy of Needs, as were the equilateral for animals (and yes animals have an objective Hierarchy of needs that consists of acquiring sustenance, shelter, safety, and other facets). For humans additions would be social acceptance and integration of self-esteem and self-glorification.. Anyways sorry if you already knew that, just wanted to give some people a chance to feel smart. So about the experiment... the researchers created an environment in which deprivation of the basic needs transgressed and estranged their psyche, causing a response of agitation, somewhat of pathological hysteria, and a bit more benign but as presentable, anxiety. This, however was seen just as advently in animals, suggesting that we share many of the same characteristics in terms of our desires and necessities, painting the picture of humbleness.
