In the spinal cord takes place the first relay of sensory (and in particular nociceptive) information, as well as the last relay of motor command. Sensory information is integrated at the spinal level and can directly induce a motor response, or be relayed to supraspinal centers where they will contribute to the planification of motor actions.

Our projects aim at elucidating the neuronal circuits responsible for the integration of nociceptive sensory information in the dorsal spinal cord, and more broadly, for the sensorimotor integration at the spinal level. In particular, we are interested in:

  • spinal dorsal horn cholinergic interneurons, involved in cholinergic analgesia
  • spinal cholinergic premotor V0c neurons, at the interface between sensory and motor pathways
  • spinal targets of the corticospinal pathway, involved in sensory or motor control
