Presynaptic modulation by metabotropic glutamate receptors of excitatory and inhibitory synaptic inputs to hypothalamic magnocellular neurons.

The effects of activation of metabotropic glutamate receptors (mGluRs) on synaptic inputs to magnocellular neurons of the hypothalamic supraoptic nucleus (SON) were studied with the use of whole cell patch-clamp and microelectrode recordings in acute hypothalamic slices. Application of the mGluR agonist trans-(+/-)-1-amino-1,3-cyclopentane dicarboxylic acid… (More)
