Studying tactile feature encoding in the somatosensory cortex for optimizing a closed-loop brain-machine interface in mice, by Daniel Shulz
Abstract Studying tactile feature encoding in the somatosensory cortex for optimizing a closed-loop brain-machine interface in mice
Tactile information is acquired and processed in the brain through concerted interactions between movement and sensation. We study neuronal processes responsible for the coding of sensorimotor information in the barrel cortex of rodents by using a comprehensive approach including electrophysiological, imaging, optogenetic and behavioral strategies. We use this knowledge to optimize the sensory feedback injected to the brain for improving the motor control of a brain machine interface.
Daniel Shulz is Director of Research 1st class CNRS in Sensory-motor integration and Plasticity lab (PI). He is heading the Department of Integrative and computational neuroscience in Paris-Saclay Institute of Neuroscience.
“I obtained my Bachelor of Science degree at the Hebrew University of Jerusalem in Israel, a Master degree in Medical Sciences and Neurobiology at the Hadassah School of Medicine in Jerusalem, and a Ph.D. in Neurosciences at Paris-Sud University in Orsay (France). Since 2002, I serve as Director of Research at the French National Center for Scientific Research (CNRS). I was director of the unit CNRS-UNIC (Gif sur Yvette) and I am presently PI of the Sensori-motor integration and plasticity laboratory, head of the Department of Integrative and Computational Neuroscience and member of the Steering committee of the Paris-Saclay Institute of Neuroscience in Saclay (France). I teach Sensory physiology at several French universities and Institutes (Université de Paris-Saclay, Université de Paris Diderot, ENS Paris, ENS Paris-Saclay, CentraleSupélec). I was invited professor at UCSD (USA) and at the Weizmann Institute of Science (Israel). I am an honorary member of the Society of Neuroscience of Argentina and in charge of the international relationships with South American countries for the French Société des Neurosciences.
My current research interest includes the study of sensory processing, sensori-motor integration and plasticity and the neural basis of perception and learning (see selected publications below). More specifically, we study neuronal processes responsible for the coding of sensorimotor information by using a comprehensive approach including electrophysiological, imaging, optogenetic and behavioral strategies in rodents. Our general strategy is to probe the brain with controlled natural tactile inputs in vivo, in order to gain understanding of the functional architecture of the system and the plasticity rules that underlie perceptual learning and motor control. Within the framework of closed-loop neuroscience, we explore general rules of sensorimotor adaptation by developing brain-machine interfaces used as a probe for studying the neuronal code and its adaptation by reinforced learning”.
