PSY290H5 Lecture Notes - Lecture 1: Trepanning, Cerebral Cortex, Neuroscience
Document Summary
It is all about understanding the relationship between behaviour and brain. Neuroscience: it is the study of neurones and nervous system. The notion that we use only 10% of brain is a myth, actually we use. Lashley removed large areas of the cerebral cortex in rats and found that these animals could still relearn speci c tasks. 10% of human brain, so try to imagine how we would function with 10% of the brain. Parkinson"s disease symptoms begin when the loss of dopamine reaches a critical point, typical when 50-80 percent of dopamine neurones have died. 200,000 dopaminergic neurons, 80,000,000,000 neurones in the human brain. So, we only need to loose 0. 000125% to have a dramatic effect on how we live. So, we use almost 100% of hour brain!!! Trephining was used to get rid of some mental. Monday, january 5, 2015 problems, this evidence shows that some form of brain surgery was performed.
