Scientific Focus
Current Research Interests
Our laboratory uses electrophysiological techniques to study the mechanisms of synaptic transmission and plasticity in the mammalian hippocampus. One of the main focuses in the lab is in the study of synaptic long-term potentiation (LTP). LTP is the persistent increase in synaptic strength that occurs after a period of heavy activity in a synaptic connection. It is the most widely studied and compelling model for mechanisms underlying memory formation in the mammalian central nervous system. Most recently, we have been involved in studies of the intracellular messenger, nitric oxide. Nitric oxide appears to play a role both in inducing LTP and also in communicating LTP between groups of unconnected synapses, thus creating funcitonal domains of alterered synapses.
The other major focus of the lab is the study of the modulation and short term plasticity of inhibitory synaptic transmission in the hippocampus by different neurotransmitter systems. Projects under this focus include studies on the modulatory properties of norepinesphrine, acetylcholine and opiates on hippocampal inhibitory circuitry and transmitter release.
Studies in the lab are carried out using a full range of electrophysiological techniques including extracellular field potential recording, intracellular recording,whjole cell and single channel recording in hippocampal slices and cultured neurons.
