Lecture 11 Flashcards
Long term potentiation
assoicated with short term memory
a longer lasting increase in the strength of the synaptic connection and the size of the post- synaptic potential requiring new gene expression in response to repeated activation of a synapse
Late LTP
longer term memory and long term increases or decreases in synaptic transmission
Long term memory (ex: personal memories; how to ride a bike)
longer term memory involves much larger and longer acting changes in synaptic communication between neurons requiring new gene expression
Late LTP or longer term memory
a long term increases in synaptic transmission
short term memory
lasts minutes to hours or even days ( seems to increase the strength or duration of short term memory
adult neurogenesis
formation of new neurons in the adult brain
requires extensive gene expression and cell division
increases number of neurons available for synapse formation
is much longer lasting than habituation or LTP
where does adult neurogenesis occur
in the hippocampus
Retrograde amnesia
the loss of pre existing memories (defect in storage or retrieval)
anterograde amnesia
inability to form new memories ( defect in encoding and consolidation)
The loss of explicit memory of amnesia
physical trauma
alzheimers disease
korsakoff’s syndrome
psychological trauma
the loss of implicit memory amnesia
parkinson’s disease
huntington’s disease
physical trauma to the basal ganglia or cerebellum
