WebLong-term depression (LTD) is the opposite of LTP, and is characterized by a decrease in postsynaptic strength. This happens by dephosphorylation of AMPA receptors and the facilitation of their movement away from the synaptic junction. LTD is prominently seen in the hippocampus and cere-bellum, though current research shows LTD in other areas ...
