Document Summary
Lecture 2: a brief history of biological and cognitive psychology. Cut of a certain part of the brain to avoid seizure. Although there are lots of nerves, there is no pain receptor in the brain; people get headache because there is pain receptor in the spaces of the brain and inside the skull. He used a needle-like device and give the brain electro signal/ current into it and simulation things in people"s brain (e. g. they can see somethings that is not there, like colours) Prefrontal (silent cortex): he believed that because it has no response with the electro current, it is only spaces for human evolution; very wrong, it is actually the most important part in human for cognitive system (?) Neuron: very fast but slower in electrical trans-mission; they are not connected to each other but use chemical to connect to each other.
