Long-term potentiation
Repeated high-frequency stimulation of a hippocampal synapse makes the postsynaptic response stronger for hours to weeks. This process, thought to underlie learning, is:
Answer A: explanation for every choice
A
Correct. LTP is a lasting increase in synaptic strength after repeated stimulation.
B
Habituation is a decreased response to a repeated stimulus.
C
Synaptic pruning is the elimination of unused synapses during development.
D
Neurogenesis is the formation of new neurons, not strengthening of existing synapses.
TakeawayLTP: cells that fire together wire together.
