Some myths


Well hi everyone this post will be about a summarise of a chapter that we had to read
This book is about the myths in neuroscience, a look of the facts that based the myths and the studies that test them
For this summarise I will write about the myth that talks about the supposed that we only use the 10% of our brain.
Some say that this myth comes from Einstein, who responded once during an interview that he only used 10% of his brain .Early research on the brain may have supported this myth. In the 1930s, Karl Lashley explored the brain using electric shocks. As many areas of the brain did not react to these shocks, Lashley concluded that these areas had no function. This is how the term “silent cortex” came into circulation. This term refers to the zones of the brain that don't have a direct relation between stimulation and action, this parts works related with superior cognitive process linking different parts of the cortex like the primary visual cortex with the secondary one and the superior visual cortex making the process of the stimuli and the information more elaborated and complex. One of the reasson that refute this myth is that evolution does not allow waste
, and the brain, like the other organs but probably more than any other, is moulded by
natural selection. It represents only 2% of the total weight of the human body but
consumes 20% of available energy. With such high energy cost, evolution would not have
allowed the development of an organ of which 90% is useless.
well this is an interesting myth because I personally believe it a few time ago before I study this in neuroscience and neuroanatomy, for the same reason I agree with the author
This was a very resume work because of the restriction of the word but its all that I cand do for this time.
So wait for my new post

Bye
