Class 6 Flashcards
Classical Conditioning
typing of learning when a neutral stimulus produces a response after being paired with stimulus that naturally produces a response
Unconditional Stimulus (US)
something that reliably produces a naturally occurring reaction in an organism (food)
Unconditioned response (UR)
reflexive reaction that is reliably produces by an unconditioned stimulus (dog salivates to food)
Conditioned Stimulus
previously neutral stimulus that produces a reliable response in an organism after being paired with a US (bell paired with food)
Conditioned response
reaction that resembles an unconditioned response but is produced by a conditioned stimulus (bell causes salivating)
second order conditioning
type of learning where a CS is paired with a stimulus that became associated with the US in an earlier procedure (black box paired with bell which was originally paired with food)
CS+US—->
UR
bell and food will cause salivating
CS—->CR
bell will cause salivating
Amygdala
activation of neurons elicits fear response (US)
Hippocampus
part of the brain neural representation of context (CS)
Hippocampus and amygdala cause…
lasting change in circuit so now the conext alone can elicit a fear response
just learn this:
different contexts have distinc hippocampal representations (rat going from opaque box to clear box)
Activating neural representation previously associated with stimulus can elicit conditioned response in new context
Context fear memories are specific to context
Leisioning the hippocampal neurons representing context associated with fear results in lack of expression
cells that fire together wire together
damn. this shits fucked. make sure u dont kill urself over some of the dumb shit you put in these flashcards and go back and look at drawing of the neuron and other bullshit
