The dorsal horn of the spinal cord is involved in the integration of nociceptive messages from peripheral primary afferent nociceptors. When transferred to supraspinal centers this information can lead to the perception of pain. We aim at understanding how nociceptive information is processed and modulated by neuronal and glial networks of the dorsal horn, and how plastic changes underlie the development of chronic pain states.
To reach this goal, we are studying native neuronal networks (spinal cord slices) or reconstituted networks (cultures of neurons and glial cells from the dorsal horn or from the dorsal root ganglia), as well as the interactions between neurons and glia, using electrophysiological methods and fluorescent probes imaging.
- Modulation and plasticity of spinal inhibition
- Activity-dependent plasticity of inhibitory synapses in the dorsal horn
- Calcium signalling and information processing in dorsal horn glial cells
- Nociceptive networks in the valproate mice model of autism
