The functions of rewards are based primarily on their effects on behavior and are less
directly governed by the physics and chemistry of input events as in sensory systems …

Spastic paresis follows chronic disruption of the central execution of volitional command.
Motor function in patients with spastic paresis is subjected over time to three fundamental …

Abstract Study Objective: To identify brain regions underlying the fastest and slowest
reaction times on the Psychomotor Vigilance task (PVT) under well-rested conditions, as …

Event-related potential studies in man suggest a role for the supplementary motor area
(SMA) in movement preparation, particularly when movements are internally generated. In a …

Though it is well known that humans perceive the temporal features of the environment
incessantly, the brain mechanisms underlying temporal processing are relatively …

Cross education is the process whereby training of one limb gives rise to enhancements in
the performance of the opposite, untrained limb. Despite interest in this phenomenon having …

In this study, we utilized functional magnetic resonance imaging (fMRI) to examine which
brain regions contribute to feedback and feedforward motor control processes. Several …

The spiking activity of single neurons in the primate motor cortex is correlated with various
limb movement parameters, including velocity. Recent findings obtained using local field …

Parkinson's disease (PD) patients have difficulty in initiating movements. Previous studies
have suggested that the abnormal brain activity may happen not only during performance of …

Progress in our understanding of the mechanisms underlying the cardinal motor
abnormalities of Parkinson's disease (PD), in particular akinesia and bradykinesia and their …
