Glutamate release and neuronal injury after intrathecal injection of local anesthetics.

abstract：:Brief tetanic stimulation of parallel fibres can evoke a slow excitatory postsynaptic potential (EPSP) in cerebellar Purkinje cells that is mediated by metabotropic glutamate receptors (mGluRs). It is likely that the receptor subtype involved is mGluR1, which couples to the production of diacylglycerol and inositol-1,...
