Flashcards in Learning and Memory Deck (19):
By when do we have most of our brain cells?
What happens in brain development between the ages of 0 and 3?
What happens in brain development after the age of 3?
What was patient HM unable to do?
Convert short-term memories to long-term memories
In what part of the brain did HM have a lesion?
Bilateral medial temporal lobe
Are memories encoded in just one area of the brain?
What part of the brain encodes declarative memories?
Medial temporal lobe
What part of the brain encodes skills and habits?
What part of the brain encodes emotional responses?
What part of the brain encodes skeletal musculature from basic associative learning?
What encodes non-associative learning?
Where are memories stored?
What improves learning and memory in mice with brain damage?
Enriched environments > increased neuronal plasticity
How does neuronal plasticity change with age?
How is short-term memory stored?
Insertion of AMPA receptors
Phosphorylation of receptors
Enhanced pre-synaptic release via retrograde signalling
How is long-term memory stored?
What does exercising the brain do?
Release of growth factors
Generation of new neurons
Improvements in mood and memory
What does exercise do to the brain?
Increases blood flow
