Abstract

This commentary argues that (1) arousal is not sufficient to induce LTP in the hippocampus, (2) learning can profoundly modulate synaptic plasticity in a state-dependent manner without affecting baseline synaptic efficacy, and (3) unilateral, synapse-specific LTP induction triggers an interhippocampal communication manifested as bilateral increases in gene expression at multiple sites in the hippocampal network.
