Engram
physical embodiment of the memory , changes in the brain e.r. plasma membrane changes
procedural memory
skills, unavailable to conscious mind, implicit memory, learnt by practicing
declarative memory
actual knowledge, explicit, transfer through teaching
where is the working memory located
prefrontal cortex
hippocampus role in memory
convert hot memory to long term, declarative, if lesions e.g. mouse in water with platform
amygdala role in memory
sensory inputs eg. smell
emotional, learnt, fear association
cerebellum role
sensorimotor information is stored
Hebbian synapse concept
modification made in synapses, plasticity, strength of synapse can change
Long term potentiation -
strengthening of a synapse. requires synaptic responsivity modification and protein phosphorylation to change activity
depression of facilitation -
decrease in nt so decrease in EPSP amplitude.requires synaptic responsivity modification and protein phosphorylation to change activity
Aplysia Californica
snail has gill withdrawel reflex as delicates and needed for respiration so remove
if apply electric shock it withdraws gill quicker
