The actions of glutamate in the central nervous system are mediated through interaction with fast activating ionotropic receptors and G protein-coupled metabotropic glutamate receptors (mGluRs). Studies of these receptors have relied on the availability of agonists and antagonists selective for

Chronic neuropathic pain remains an unmet clinical problem because it is often resistant to conventional analgesics. Metabotropic glutamate receptors (mGluRs) are involved in nociceptive processing at the spinal level, but their functions in neuropathic pain are not fully known. In

Ribbon synapses transmit information in sensory systems, but their development is not well understood. To test the hypothesis that ribbon assembly stabilizes nascent synapses, we performed simultaneous time-lapse imaging of fluorescently-tagged ribbons in retinal cone bipolar cells (BCs) and postsynaptic
