Neurobiology of learning and memory

Question 1

what does learning and memory depend on?

Answer 1

it relies on changes in brain chemistry and physiology, the extent of which depends on neuroplasticity, which decreases as we age.

Question 2

Long-term potentiation,

Answer 2

this is responsible for the conversion of short-term to long-term memory, and is the strengthening of neuronal connections resulting from increased neurotransmitter release and adding of receptors sites
