Q

Long term potentiation

A

Wire together, fire together, but pre and post synaptic firing

17
Q

Which receptors correlate with LTP

A

NMDA

18
Q

What is needed for NMDA receptors to respond?

A

glutamate binds
partially depolarized
Ca2+ entry tiggers the events that lead up to LTP

19
Q

How are LTP bonds expressed and maintained?

A

Structural changes including number/type of synapses, as well as number of spines, dendritic branching
Expressed through postsynaptic neurons and then presynaptic via unconventional neurotransmitter: nitric oxide
