Electrophysiological Methods for Mapping Brain Motor and Sensory
... • Harder than sensory mapping • Activation of muscles in isolation is difficult • Motor fields: all movements that engage a neuron • Functional (type of movement) • Structural (target muscles) • Neuroantomic labeling • TMS ...

We are investigating the use of novel stimulus
... We are investigating the use of novel stimulus waveforms in neural prostheses to determine whether they can provide more precise control over the temporal and spatial pattern of elicited activity as compared to conventional pulsatile stimulation. To study this, we measured the response of retinal ga ...
