Mykhalo G. Moldavan, Ph.D.
Senior Research Associate, Laboratory of Dr. Charles Allen
He is studying the modulation by presynaptic receptors of optic nerve signaling, the properties of the GABAA tonic current, and the contribution of GABA spill-over and GABA transporters to this current in the hypothalamic suprachiasmatic nucleus.
Study of the mechanisms underlying the GABAB receptor-mediated modulation of glutamate release from retinohypothalamic tract terminal in suprachiasmatic nucleus (SCN). Investigation of the role of the SCN in circadian rhythm regulation. Electrophysiological studies of sensorimotor, associate cortex and reticular thalamic nucleus neurons during conditioning; participation of caudate putamen (striatum) in motor control; electrophysiology and pharmacology of hippocampal, motor cortex and hypothalamic neurons (slices, in vitro studies).
