Research projects:
Our project aims to study mammalian spinal neural networks involved in motor functions. Two major themes emerge from this project. Firstly, we investigate the cellular and synaptic mechanisms which allow the various neuronal networks engaged in rhythmic (such as locomotion and respiration) and non-rhythmic (such as posture) motor activities to operate independently or together as they necessarily do during normal behavior. In this context, we seek to determine i) the key elements of neural networks responsible for generating or modulating locomotor output patterns, and ii), the mechanisms involved in locomotor-postural control and locomotor-respiratory couplings. Second, we explore the plastic capabilities of the ventral spinal cord that contains the neural circuitry responsible for posture and locomotion under both physiological and pathological conditions. To this end, we investigate the activity-dependent plasticity of excitatory and inhibitory synapses onto lumbar motoneurons during normal development and following spinal cord injury. A combination of in vitro and in vivo experimental approaches are employed mainly in rodents (neonatal, juvenile and adult rat and mouse), and a part of our project is conducted on humans.
