Sensorimotor Control Laboratory or Vinjamuri Lab studies Brain-Machine Interfaces (BMIs) that control upper-limb prostheses. In particular, we are interested in how the brain controls complex hand movements. The human hand has about 30 dimensions in contrast to a human arm with only 7 dimensions. BMIs that control human arms have already been demonstrated with decent accuracies. What type of interface is needed to extend the control from 7 to 37 dimensions forms the central topic of research of the lab. This question is answered from several approaches: a descending approach, studying neural recordings corresponding to human movement and behavior; an ascending approach, studying human hand kinematics, studying the nature and representation of muscle activities during hand movements. These studies involve application of linear and nonlinear signal processing, control and optimization methods.
