RESEARCH AREAS:
hypothalamic regulation of reproductive mechanisms, food-intake, and circadian rhythms
integration of hypothalamic information processing on neuronal and subcellular level
role of neuronal energy expenditure and synaptic plasticity in the hypothalamic control of the physiological mechanisms
Recent results:
We found a novel regulatory mechanism in the hypothalamus through examining the ATP hydrolyzing activity of NTPDase3 enzyme. We provided remarkable evidence on functional asymmetry in the neuroendocrine hypothalamus related to the estrous cycle. Our preliminary data also indicate that this functional asymmetry might affect other regulatory centers of physiological processes in the hypothalamus.
