Document Summary
Associative learning: classical conditioning in classical (pavlovian) conditioning, a stimulus that previously had no effect on behavior becomes able to evoke a reflexive conditioned response this procedure involves the repeated pairing of two stimuli. Neural stimulus + unconditioned stimulus unconditioned response. 83: the ucs is detected by a single neuron in the somatosensory system, the cs is detected by a single neuron in the auditory system, the cr is controlled by a single neuron in the motor system. When action potential reaches synapse t, the epsp is too weak to make the neuron fire. Synapse p is a strong synapse because a blink is a defensive reflex: for conditioning, the cs must be followed almost immediately by the ucs. The hebb rule the hebb rule states that the cellular basis of learning involves the strengthening of a synapse that is repeatedly active when the postsynaptic neuron fires.
