Roles of metabotropic glutamate receptors in LTP and LTD in the hippocampus.

abstract：:In the mammalian cortex, the classic view assumes that the output information of a neuron is encoded in rather stereotyped action potentials, which provide an all-or-none or digital way of communication between cell body and axonal boutons. A role for subthreshold signal propagation within cortical axons has largely b...
