Being expert
" The emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world class expert_in anything. …ten thousand hours is equivalent to roughly three hours a day over 10 years."
___from <This is your brain on music>
Most people cannot reach this target even they do it for 10 years, but even genius like Mozart need 10 years to become world class expert…..and what we get concensus is that gene and eviroment play roles in fifty-fifty.
I went to a seminar today, it’s on neurophysiology study of memery in hippocampus of rats. They record electrical signals from singal cells, whcih is quite accurate response of brain activity when the rat doing memory works, such as running on a wheel. what they discover is that different cells in different brain area are responsible for different tasks, like space identify or object identify, and CA3 and Dentate gyrus is the structure where integration or binding of memory happens.
