Journal ArticleDOI

Rapid reversible modulation of human motor outputs after transient deafferentation of the forearm A study with transcranial magnetic stimulation

TL;DR: The amplitudes of MEPs from biceps, which was the muscle immediately proximal to the block, gradually increased with anesthesia and then returned to preanesthesia levels within approximately 20 minutes after anesthesia was ended, strongly suggest unmasking of preexisting synaptic connections.
Journal ArticleDOI

Deficit in classical conditioning in patients with cerebellar degeneration

TL;DR: The role of the cerebellum and its associated brainstem circuitry in the acquisition of the conditioned response has been investigated in this paper, where the eye-blink conditioned response in five patients with pure cerebellar cortical atrophy and seven patients with olivopontocerebellar atrophy.
Journal ArticleDOI

Electroencephalographic measurement of motor cortex control of muscle activity in humans.

TL;DR: The present findings suggest temporal coding of the oscillatory motor control system (3-13 Hz vs. 14-50 Hz), and confirm the functional importance of cortical beta and gamma rhythms in the motor efferent command.
