Compare short-term memory versus long-term memory with regard to specific changes that are thought to occur in the brain
What will be an ideal response
Short-term memory depends more on electrical and chemical events in the brain than on structural changes, such as forming new synapses. Long-term memory is thought to involve high-frequency stimulation within the hippocampus at glutamate synapses. Nitric oxide and other neurotransmitters may also be involved. For long term memory, neurons develop new presynaptic terminals, larger synaptic end bulbs, and more dendritic branches.
