Projects

Motor Unit Physiology – Alex Weatherly, Dr. Thuy Pham, and Dr. Brad Harwood record single motor unit activity from tibialis anterior muscle while subject performs controlled isometric contractions

Upper Limb Neuroprosthetic – Alie Buckmire and Dr. Katalin Gothard begin surgery to implant several muscles of the upper limb in a non-human primate with recording/stimulating electrodes.

Electrotactile feedback – Touch and movement sensors placed on hand of experimenter provide sensory feedback about grasped objects to subject through electrodes placed on the back of the neck.

Multi-Site Stimulation of Muscle – Multiple electrodes inserted into human tibialis anterior muscle to test whether multi-site stimulation can increase force and reduce fatigue associated with functional electrical stimulation of paralyzed muscle.

Motor Unit Recording in Awake Behaving Rats – Pareena Kaur prepares experiments to record motor unit activity in rats performing voluntary motor task.

Neural Control of the Hand – Electromyographic recording from several hand muscles in experiments to better understand the orchestration of multiple muscles in the elaboration of finger movements.

Modeling Motor Unit Physiology – Computer models are used to simulate and better understand the organization of motor unit populations. (see Potvin & Fuglevand 2017)
