PSYC 375 Lecture Notes - Lecture 24: Primary Motor Cortex, Premotor Cortex, Motor Cortex
Document Summary
Find out the connection with in the human brain. Dti doesn"t tell us where all the nerves are connected, just major connection. We get less echo from de-phases region. The highlighted/lightened area of brain is more active than fmri the surrounding. Fmri sees changes in ration of oxygenated to de-oxygenated blood. Fmri is slower as it measures the blood flow. Inferring activity of brain depending on blood flow. Fmri: blood flow is directly connected to neural activity. It"s hard with pet: karl lashely: we have motor sequences in our brain. It"s a back to back process: how do we initiate movement: prefrontal, premotor and primary motor cortex, prefrontal cortex: planning. Not limited to movement: premotor cortex: speaks to pfc. There is movement but not in an accurate order. Watching a person do a certain task light up the same area in our brain that lights up in theirs.
