Until not long ago - in academic circles - it was believed that the human brain could have a limited number of neurons and that once they had been damaged by accident and / or physiological (eg. accidents, stroke, degenerative diseases, etc..) is no longer possible to recover the destroyed neurons and consequently reactivate the functional areas affected. today - instead - we talk more and more about neuroplasticity : it seems that our brain is capable of producing new neurons and that they will "activate" with the attention focused and their ready for use. Another factor which seems to favor the emergence and activation of new brain cells is a symmetrical physical activity (eg. Walking, running, swimming) activities, those that also promote a greater synchronization of left and right cerebral hemispheres . However, according to the known rule - valid in nature - "Use it or Lose it" is important that new brain cells are involved in a process that involves and to enable the rapid establishment of new synaptic connections. All that is not used, is eliminated from the nature.
As reported by Norman Doidge - psychiatrist, psychoanalyst and researcher at the U.S. - would exist in the literature documented cases of patients blind from birth that they would begin to see, functional recovery after stroke, disabling, significant improvements memory after 80 years of age.
How can we explain this?
The answer is to be found - of course - in the brain neuroplasticity. neurons and connections created between them are continually modified. On the contrary: it seems that 90% of our brain remain unused because of ... Why Nature perpetuates the existence and reproduction of physiological characteristics that do not appear (apparently) to perform a specific function?
According to recent estimates, our brain is made up of about 100 billion nerve cells, each neuron is able to establish an average of 1000 synaptic connections with other neurons (in cases of particularly complex ramifications, a single neuron can handle tens of thousands of synaptic terminals); axons that connect neurons together can exceed one meter in length ... In short: our brain system is a system so complex as to contain a number of synaptic connections more than ten orders of magnitude the number of subatomic particles present in the known universe!
why the title adopted for his study by Doidge, The Brain Infinite , surely guessed it: what we know of our brain, its incredible complexity, its exceptional ability to self-regenerate and the power that the human mind can have on biological devices (and reality in general) is still very low ... But the man of the twenty-first century is now one step away from her forthcoming "awakening" to remember who and what is truly amazing and extraordinary ability (now dormant) can have.
