COGS 11 Lecture Notes - Lecture 10: Phineas Gage, Frontal Lobe, Visual Cortex
Document Summary
Lecture 10: neural basis of decision making 11/01/18. Top-down processing: consciousness, starting at a higher level going down to a less abstract point. Bottom up representation: starting with the fundamental components and building up a representation of that. Effect of one is the input of the next one. Retina -> thalamus -> primary visual cortex -> higher processing. Top down processing: filling in information about representations. For ocd a critical part of the treatment is to relabel the problem. Being able to be conscious of what you"re doing -> helps break habits. Ocd is located in the orbital frontal lobe. Orbital - the area with bone around your eye. The biggest risk with the brain is infection. Phrenologists: believed that your personality is encoded in the bumps in your head. Anterior cingulate gyrus- drives watching what you"re doing. The functions of the orbital frontal cortex. Orbital frontal cortex drives the decision to do something rewarding.
