Catherine Woolley

Catherine S. Woolley (born July 30, 1965) is an American neuroendocrinologist. Woolley holds the William Deering Chair in Biological Sciences in the Department of Neurobiology, Weinberg College of Arts & Sciences, at Northwestern University. She is also a member of the Women's Health Research Institute in the Feinberg School of Medicine at Northwestern University.

Woolley studies cellular and molecular neuroscience in relation to the brain and behavior, particularly neuroendocrinology and the plasticity of neural circuits. anxiety and depression.

Early life Catherine S. Woolley was born on July 30, 1965, in Nelsonville, Ohio. She graduated from Texas A&M University in College Station, Texas, with a B.Sc. honors in zoology and was given a prize by the university for the best undergraduate honors thesis.

Career Woolley studied with Bruce McEwen at Rockefeller University, receiving her Ph.D. from Rockefeller in 1993. She did postdoctoral work at the University of Washington with Philip Schwartzkroin in the Department of Neurological Surgery.

She was elected to the Council of the Society for Neuroscience (2014–2018). She is a senior editor of The Journal of Neuroscience.

Research Rockefeller University Bruce McEwen at Rockefeller University studies stress and its impact on the brain. The study showed that estradiol increased the number and density of excitatory synapses of CA1 pyramidal cells in the rat hippocampus, as well as the density of dendritic spines. Both estradiol and spine density fluctuated dramatically during the estrous cycle. Woolley recognized that this suggested that the adult brain was subject to change, at least in rats; this was surprising because it was accepted at that time that the adult brain was structurally stable. Woolley's 1990 work is considered a pioneering study in hormones and synaptic plasticity. Further work established that the manipulation of female sex hormones affects hippocampal structure in adult rats.

University of Washington Between 1993 and 1998, Woolley worked as a postdoc at the University of Washington in Seattle, with Philip Schwartzkroin. There she applied electrophysiology techniques and ultrastructural analysis to the study of hormonal effects in the brain. She studied the effects of estrogen on the release of GABA in the hippocampus. In 2000, she received the Cortical Explorer Award in recognition of her work on neuroanatomy and brain activity. As a professor at Northwestern University, Woolley has done ongoing research into the sex-specific effects of estrogens, GABAA receptors, metabotropic glutamate receptors, and endogenous cannabinoids and their roles as neuromodulators of brain development and function. In 2012, Woolley published research showing that estrogens had differential effects in the brains of female and male rats, decreasing inhibitory synaptic transmission in female rats but not in males. In 2015, her group reported that male and female rats differ in the molecular pathways affected by endocannabinoids. In female rats the drug URB-597 increased the inhibitory effect of the endocannabinoid anandamide, lessening the release of neurotransmitters. In male rats, the drug had no effect. The interaction did not reflect circulating reproductive hormones. 2007: C.J.
