Document Summary
Key point of lecture- ways to measure brain activity. Blood flow indicates brain location of mental processes (mri, pet scans) Frontal decision making, planning, goals: executive area. Parietal attention (not just once center: vision hearing and touch. We learn lots about our brains by studying monkey brains. How a system works by breaking one area. Usually added to different data thought different research methods to come up with findings. He thought he would try and find the memory area in a rat brain (but there are many different areas for memory) Galvani- thought about electricity in the brain (a shocking discovery) Had a machine called leyden jar (is like a battery) Got the ball rolling for brain and electricity research/discoveries. Putting a microelectrode into an axon/brain tissue. Figure out when the neurons in that area become active by neural firing. Used for finding out what part of the brain is for what function.
