Biography

Matthew G. Perich is an assistant professor in the Department of Neuroscience at Université de Montréal. His research program fuses AI and computational neuroscience with experimental neurophysiology and neural engineering to study how biological brains coordinate motor behaviours and ultimately guide the development of next-generation neuroprosthetic devices for rehabilitation.

Motor cortex latent dynamics 1 encode arm movement direction and 2 urgency independently 3

10 The fluid movement of an arm is controlled by multiple parameters that can be set 11 independently. Recent studies argue that arm moveme… (see more)nts are generated by the collective 12 dynamics of neurons in motor cortex. But how these collective dynamics simultaneously encode 13 and control multiple parameters of movement is an open question. Using a task where monkeys 14 made sequential, varied arm movements, we show that the direction and urgency of arm 15 movements are simultaneously encoded in the low-dimensional trajectories of population 16 activity: each movement’s direction by a fixed, looped neural trajectory and its urgency by how 17 quickly that trajectory was traversed. Network models showed this latent coding is potentially 18 advantageous as it allows the direction and urgency of arm movement to be independently 19 controlled. Our results suggest how low-dimensional neural dynamics can define multiple 20 parameters of goal-directed movement simultaneously. 21
