Neural Mechanisms
The results of behavioral experiments addressing neural control of the hand are often used to infer the underlying neural mechanisms. However, behavioral results are sometimes not sufficient to identify such mechanisms. Therefore, in our work we have integrated research tools to complement our behavioral approaches. Specifically, we are using non-invasive brain stimulation (transcranial magnetic stimulation, TMS; transcranial focused ultrasound, tFUS), neuroimaging (electroencephalography, EEG) and peripheral nerve stimulation to understand mechanisms underlying cognitive control, gating of sensory inputs, as well as motor planning, learning and execution. Below are some examples of our research in this area.
Grasp context-dependent sensorimotor cortical interactions
Previous work on grasping and manipulation has used a grasping context that predominantly elicits memory-based control of digit forces by constraining where the object should be grasped.
