Dr. Moldavan received his Bachelor of Science in Biology from Kyiv State University in Kyiv, Ukraine and his Ph.D. in Physiology from the Bogomoletz Institute of Kyiv, Ukraine in 1992. PhD Thesis: Reticular thalamic nucleus spike activity adjustments during conditioned instrumental reflex".
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).Read more
