PSYCH 2GG3 Lecture Notes - Lecture 5: Biological Neural Network, Motor System, Classical Conditioning
Document Summary
Lecture 5 the neural model of classical conditioning. Hebb rule: if a synapse repeatedly becomes active at about the same time that the postsynaptic fires, changes will take place in the structure and chemistry of the synapse that strengthen it. Imagine purple neuron allows for us to blink our eye. The powerful stimulus naturally leading to a response = the puff of air. Both of these are happening at the same time. What ends up happening, is if you take a strong synapse and activate it at about the same. If we present a neutral stimulus (such as a sound) that is a weaker stimulus time as the weak synapse, then the weak synapse is going to become stronger. How this relates to cc: take something strong and pair it with something weak and therefore the weaker synapse will become stronger.
