Genetic Engineering of Mammalian Sensory Circuits

Optogenetics has emerged as a powerful tool to control neuronal activity with high spatio-temporal precision. We were the first to develop optogenetic strategies to activate selectively genetically-defined peripheral somatosensory neurons involved in nociception and pain in mice (Daou et al., 2013). In this 5-year research program, we propose to design and validate conditional transgenic models for the functional interrogation of neuronal subsets with unclear roles in somatosensory circuits.
