The new team results from the fusion of 2 teams and our objective is to capitalize on the complementary expertise to investigate key pathophysiological processes that lead to motor neuron (MN) degeneration and neuromuscular disorders such as Amyotrophic Lateral Sclerosis (ALS) and Congenital Myasthenia Syndromes. Our team assembles a unique spectrum of expertise allowing us to investigate all the components of the motor units (inputs to MNs arising from spinal and supraspinal circuits, properties of motor neurons, neuromuscular junctions, and muscle fibers).
