Presentation

**Armelle Rancillac**, PhD, HDR Inserm researcher Neuroglial Interactions in Cerebral Physiopathology CNRS UMR 7241 / Inserm U1050 Center for Interdisciplinary Research in Biology - CIRB Collège de France 11, place Marcelin Berthelot 75005 Paris Armelle Rancillac earned her PhD in Neuroscience in 2003 at Paris VI, while working with Francis Crépel and Hervé Daniel on synaptic plasticity using patch-clamp recordings on cerebellar slices. In her dissertation, she described for the first time, several forms of synaptic plasticity between stellate cells and parallels fibers. Then, she joined Jean Rossier’s laboratory at the ESPCI ParisTech, as a postdoctoral fellow, to study the neurovascular coupling within the cerebellum. Armelle Rancillac demonstrated that cerebellar stellate and Purkinje cells dilate and constrict, respectively, neighboring blood vessels. In 2006, she got a researcher position at the INSERM and focused on the vasomotor control of intracortical blood vessels by interneurons. Combining patch-clamp, RT-PCR, infrared videomicroscopy and Neurolucida reconstructions, she characterized the roles of different interneuron subpopulations in the neurovascular coupling of the mouse somatosensory cortex. Between 2011-2015, Armelle Rancillac studied the role of metabolism on neuronal activity and blood vessel tonus within the ventrolateral preoptic nucleus (VLPO), one of the main brain structures triggering non-rapid eye movement (NREM) sleep. In 2014, she obtained here Habilitations to conduct research (HDR in French). Currently, Armelle Rancillac is working at Collège de France, in Rouach's team, to investigate how neuroglial interactions contributes to the regulation of non-rapid eye movement (NREM) sleep within the ventrolateral preoptic nucleus (VLPO).
