BIO SCI 47 Lecture Notes - Lecture 13: Muscle Memory, Cerebellum, Glucocorticoid
Stress Lecture 13
● Two types of long term memory
○ Declarative
■ “I remember”
■ Dependent on hippocampus
○ Non declarative
■ Muscle memory
■ Cerebellum, motor function
● HM had epilepsy
○ Drs cut out part of temporal lobe, hippocampus
■ Epilepsies stopped, cannot form new memories now
○ He could form new skills but not know he had those skills
● CA3 converging inputs to CA1 then goes out to the brain
○ Coming from Dentate Gyrus
■ Forms new cells
○ Moving via neurons, axons, synapses
■ The more convergence, the better memories are formed
○ Neurotransmitter release at synapses
● Presynaptic is coming in from CA1 going to next neuron in CA3
○ When neurotransmitter is taken in by postsynaptic, the electric makeup
changes
○ Rehearsal moves stuff from CA1 to CA3, long term potentiation
