Document Summary

Ltp involves an enhancement in synaptic efficacy that can last for hours, days, If one synapse (a) is very strongly stimulated (sufficient to cause ltp), and. A. b. another nearby synapse (b) on the same dendrite is weakly stimulated. A. a. another nearby synapse (b) on the same dendrite is weakly stimulated a few seconds later. A. a. an influx of ca triggers two or more intracellular processes in the postsynaptic dendritic spine. Ampa receptor phosphorylation by cam kinase ii results in increased channel conductance. A. c. ca may activate a signaling cascade that causes the insertion of glutamate receptors in to the postsynaptic membrane. A. a. ca mediated activation of cam kinase ii increases the activity of k+ channels found on the postsynaptic membrane: nmda mediated ltd in the hc depends on. Low level of nmda-mediated ca++ influx into the postsynaptic spine. Removal of ampa receptors from the postsynaptic membrane. All of the above: cerebellar ltd depends upon.
