Study of the mind has been one of the major concerns of philosophers, some of whom up to date still hold believe that the subject consciousness is inherently unclearly understood. The efforts of neuroscientists are making moves in coming up with a true picture of “science of the self.”
What is consciousness?
Just visualize the image of a mango in your brain and also how it appears in digital camera. The two objects under focus appears to be the same be the same no matter the way it is viewed. The camera values each single pixel separately and in the same manner, the brain integrates independent parts of the image so as come up with a clear object-which it is a mango and which is food. In this case, the camera can be said to be ‘unconscious’ and the brain as ‘conscious.’
Consciousness therefore has been defined as the state of being awake and being updated of what is going around you, and of having a sense of self understanding.
A French philosopher Descartes came up with the term “cogito ergo sum” which implied that, “what I think of, is what I am.” This idea raised a lot of debate within the school of thinking (philosophers) and natural scientist.
For Descartes, he held the idea that the mind was independent from the general body which a concept he referred as “mind-body duality” an idea which natural scientists greatly oppose though layman continue to support the notion that the mind is somehow removed from the virtual world. It is worth to note the concerted efforts of the philosophical scholars for coining a wide range theories of consciousness.
Scientific explanation on consciousness.
Neuroscientists from an evidence-based perspective have come to discover that human brain contains roughly 86 billion neurons and more nerve cells and that is we can form more complex thoughts than any other animal. Thus, specific neurons are linked to conscious experiences. In their report they established that the brain behaves like on-off switch. When claustrum neurons are electrically triggered, an individual become unconscious on the spot. He assumed that this region might integrate information across different parts of the brain.
However, it is ironical how the cerebral part of the brain (containing 70 billion neurons) at the back of the skull coordinates muscle processes but fail to influence consciousness, while the cerebral cortex (the brain’s peripheral layer contains 16billion neuron) does. This is the case even though the cerebellum contains more neurons than the cerebral cortex.
How do we become unconscious?
Obviousness is brought on when the framework is divided and availability in the cerebrum diminishes. This is precisely what appears to happen when in a profound rest (when we don’t dream) or under general anesthetic. Typically when wakeful and ready, quick action can be discovered everywhere throughout the mind and flags can be passed between territories. When we go into a profound rest be that as it may, the cerebrum moves to a state where signals can’t without much of a stretch go between various zones. Cells incidentally close off their associations with each other to rest and recover, along these lines losing interconnectivity and therefore unconsciousness is attained.
