The ease with which we perform tasks such as opening the lid of a jar, in which the two
hands execute quite different actions, belies the fact that there is a strong tendency for the …

In humans, execution of unimanual motor tasks requires a neural network that is capable of
restricting neuronal motor output activity to the primary motor cortex (M1) contralateral to the …

This experiment used functional magnetic resonance imaging (fMRI) to compare functional
neuroanatomy associated with executed and imagined hand movements in novel and …

Motor or sensory activity in one arm can affect the other arm. We tested the hypothesis that a
voluntary contraction can affect the motor pathway to the contralateral homologous muscle …

Performance of a unimanual hand motor task results in functional changes in both primary
motor cortices (M1ipsilateral and M1contralateral). The neuronal mechanisms controlling the …

Objectives: To test whether unilateral hand muscle activation involves changes in ipsilateral
primary motor cortex (M1) excitability. Methods: Single-and paired-pulse transcranial …

The purpose of this research was to determine whether motor cortex excitability assessed
using transcranial magnetic stimulation (TMS) is less variable when subjects maintain a …

Human locomotor adaptive learning is thought to involve the cerebellum, but the
neurophysiological mechanisms underlying this process are not known. While animal …

Although it has long been known that practicing a motor task with one limb can improve
performance with the limb opposite, the mechanisms remain poorly understood. Here we …

Planning object-directed hand actions requires successful integration of the movement goal
with the acting limb. Exactly where and how this sensorimotor integration occurs in the brain …
