We are interested in the mechanisms of regulation of neuronal gap junctions (electrical synapses) during development and neuronal injury. We also study the role of neuronal gap junctions in death of neurons in the developing nervous system and in the secondary, glutamate-dependent neuronal death following ischemic stroke, traumatic brain injury and epilepsy. As a result of these studies, a novel model of the mechanisms of glutamate-dependent neuronal death has been proposed, where neuronal gap junctions play a critical role.
