Question

Hebb’s postulate from 1949 states “When an axon of cell A is near enough to excite cell B and repeatedly or persistently takes part in firing it,
some growth process or metabolic change takes place in one or both cells such that A’s efficiency, as one of the cells firing B, is increased.”

Which of the following are examples of how synaptic plasticity results in Metabolic processes?

*Hint there are three correct answers.

A) Changes in postsynaptic receptor density
B) Increases in presynaptic neurotransmitter release
C) Elimination of spines
D) Changes in gene expression

Which of the following are examples of how synaptic plasticity results in Growth processes?
