Learning and Memory
Nature of Learning
Memories- experiences that change our nervous system and behaviour, done through learning
Perceptual learning- learn to recognize stimuli that we have seen before. Ability to identify and
categized nouns.
Stimulus-response learning- learning particular response to particular stimulus. Connects circuits used
for movement and perception
Classical conditioning- unimportant stimulus acquires properties of important one. Unconditioned
response (blinking) happens naturally when unconditioned stimulus (puff of air) occurs. Put conditioned
stimulus (beep) right before unconditioned to caused conditioned response (blink). New synapses form
between afferent neurons of conditioned stimulus and unconditioned response.
Hebb rule- sypases that are active a lot will become stronger
Instrumental conditioning- learning effected by particular behaviour in a particular situation to either
increase or decrease a behaviour. Either being rewarded or punished for a behaviour
Motor learning- changes within motor system to learn to make new response. Biking knitting, typing.
Synaptic Plasticity
Long term potential- changes in it are responsible for learning. Long term increase in excitably of a
neuron from particular neuron. Caused by increased activity. Requires activate of synapse and
depolarization.
Hippocampal formation- in temporal lobe. Specialized region of limbic cortex. Includes the hippocampus
proper Ao’s hor, detate gyrus, ad suiulu. Folded twice so very complex
Population EPSP-evoked protentional that represents excitatory postsynaptic potential of a neuron
population. First indicates strength of synaptic connection before long-term
