NEUR 001 Lecture Notes - Lecture 17: Inferior Temporal Gyrus, Tuning Fork, Perceptual Learning
Document Summary
Behavioral, cellular and molecular mechanisms of learning and memory. Perceptual learning (the idea that we store things in our brain) Associative learning (stimuli-response learning: classical (pavlovian) conditioning, was studying chemical composition of saliva, noticed that dogs salivated even before he gave them food, when they heard footsteps, and other triggers. Figured that dogs must be learning something: used tones of varying frequencies (bells, tuning fork) and he hit the tuning fork and then give the dog food. Dog didn"t salivate from the tone at first but after repeated pairings, he could play the tone by itself and the dog would begin salivating: previously neutral stimulus takes on property of biologically relevant stimulus. The biologically relevant stimulus, salivating, is called the unconditioned stimulus (us). The unconditioned response is the response to the unconditioned stimulus automatic response to stimulus that didn"t need learning. The conditioned response is the response that was learned from the neutral stimulus.
