PSYC 2240 Lecture Notes - Lecture 4: Postcentral Gyrus, Visual Cortex, Prefrontal Cortex
Document Summary
At the peak of the action potential, the electrical gradient of potassium pushes potassium out of the cell: depolarization; positive inside, pushes it out. The resting potential refers to net negative charge inside of the neuron. The net effect of each cycle of the sodium-potassium pump is to: decrease the number of positively charged ions within the cell. Discussion the mcgurk effect; visual and auditory learning: occipital lobe an dtemporal lobe play a role in the effect, mouth movement can influence us to see something different, what we hear may not be the truth. What is a lobotomy: a surgery to remove of the prefrontal cortex. And why: people can survive and be alive, how different parts of the brain work without the prefrontal cortex. What do you know about the cerebral cortex. Different brain regions work together (they do not work independently: ex. mcgurk effect. All areas of the brain communicate with each other but no single central processor.
