Define long term potentiation:
|
Long-lasting
Strengthening of the response of postsynaptic nerve cell to stimulation across the synapse Occurs with repeated stimulation. |
|
How is the NMDA receptor involved in LTP?
|
Binding of glutamat to the NMDA receptor triggers the opening of a channel which is permeable to monovalent cations (Na+ and K+) generating depolarisation
|
|
What receptor is altered during long term potentiation?
|
AMPA is phosphorylated increasing single channel permeability
|
|
What is the roleof Calcium-calmodulin-dependent-proteinkinase II (CaMKII) in generation of LTP?
|
CaMKII phosphorylates AMPA receptors.
