WebLTP typically lasts up to one hour. Which of the following is true of long-term potentiation (LTP)? LTP is the cellular basis for episodic memory. LTP occurs independent of synaptic activity. LTP reflects a persistent temporal summation of postsynaptic potentials. LTP can be produced in isolated hippocampal slices. WebLong-term depression ( LTD) is a phenomenon that is the opposite of long-term potentiation (LTP). In LTD, communication across the synapse is silenced.
