Electrophysiologial mapping of alpha and beta activity across the ventrolateral (motor) thalamus: a local field potential study

Objective: To map the distribution of alpha (8–12 Hz) and beta (13–30 Hz) activity across the ventrolateral (motor) thalamus Introduction: Neural oscillations are thought to underlie coupling of spatially remote neurons and gating of information within the human sensorimotor system. Different frequency ranges have been associated with different movements: A tonic contraction elicits beta-band-activity1, while a resting alpha rhythm at around 10 Hz can be observed over the motor cortex2,3. Different kinds of movement also elicit activity in different areas in the motor network4. Methods: We recorded local field p…
