Purkinje cell
Hippocampal/cortical LTD can be dependent on NMDA receptors, metabotropic glutamate receptors (mGluR), or endocannabinoids. The result of the underlying-LTD molecular mechanism in cerebellum is the phosphorylation of AMPA glutamate receptors and their elimination from the surface of the parallel fiber-Purkinje cell (PF-PC) synapse.
