Current Research

Dr. Dorman's research deals with the role of neuronal membranes in chemical transmission processes, and the effects of cerebral ischemia on membrane functions. He investigates effects of unesterified arachidonic acid on the release of the excitatory amino acid neurotransmitter glutamate. The release and metabolism of arachidonic acid to eicosanoids is examined in mossy fiber nerve endings isolated from the hippocampus. These nerve terminals have been implicated in learning and memory processes; they appear to be stimulated by arachidonic acid and modulated by certain eicosanoids. Although these investigations are related to the understanding of normal synaptic transmission mechanism, they also appear to be involved in the cerebral damage associated with ischemic trauma. Cerebral ischemia stimulates uncontrolled accumulation of free arachidonic acid and massive release of excitatory amino acids. The excitatory transmitters are may play a central role in neuron death and, therefore, in stroke-induced brain damage.
