I was reading the article, in which it is mentioned that human brain constitutes 2.5 petabytes of memory. This made me wonder how much of the brain is associated with memory itself. If we categorize brain by functionality, such as dedicated areas for visual processing, audible processing, logic processing, memory storage etc, what percentage of the brain is utilized for memory itself?
I speculate that the brain does more memory related tasks then any other. As a matter of fact, almost all tasks for humans requires memory, so perhaps 70-80% of brain might be just to store memory. Is this correct? If not then what percentage of the brain is used for storing memories?
