abstract：:In the vertebrate nervous system, glutamate (Glu) receptors are generally known to cause depolarizing responses. We report here a novel type of Glu response in Purkinje neurons of mouse cerebellar slices, namely glutamate-induced hyperpolarization (GH). This response is not due to activation of inhibitory interneurons...
