  • Abstract
  • Look Inside

The cerebellar long-term depression (LTD) has been a candidate cellular mechanism for the motor learning. The LTD is the long-lasting reduction of transmission efficacy at parallel fibers-Purkinje cell synapses induced by repeated coactivation of parallel fibers and a climbing fiber. The climbing fiber strongly depolarize a Purkinje cell inducing massive Ca influx. Glutamate released from parallel fibers activates the metabotropic glutamate receptor mGluR1 and the ionotropic glutamate receptor of AMPA subtype.
