Neural pathways mediating bilateral interactions between the upper limbs
RG Carson - Brain Research Reviews, 2005 - Elsevier
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 …

Neurophysiology of unimanual motor control and mirror movements
M Cincotta, U Ziemann - Clinical Neurophysiology, 2008 - Elsevier
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 …

Brain activation during execution and motor imagery of novel and skilled sequential hand movements
MG Lacourse, ELR Orr, SC Cramer, MJ Cohen - Neuroimage, 2005 - Elsevier
This experiment used functional magnetic resonance imaging (fMRI) to compare functional
neuroanatomy associated with executed and imagined hand movements in novel and …

Changes in segmental and motor cortical output with contralateral muscle contractions and altered sensory inputs in humans
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 …

Mechanisms underlying functional changes in the primary motor cortex ipsilateral to an active hand
Performance of a unimanual hand motor task results in functional changes in both primary
motor cortices (M1ipsilateral and M1contralateral). The neuronal mechanisms controlling the …

Changes in motor cortex excitability during ipsilateral hand muscle activation in humans
W Muellbacher, S Facchini, B Boroojerdi… - Clinical …, 2000 - Elsevier
Objectives: To test whether unilateral hand muscle activation involves changes in ipsilateral
primary motor cortex (M1) excitability. Methods: Single-and paired-pulse transcranial …

Variability of motor potentials evoked by transcranial magnetic stimulation depends on muscle activation
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 proportional to depression of cerebellar excitability
Human locomotor adaptive learning is thought to involve the cerebellum, but the
neurophysiological mechanisms underlying this process are not known. While animal …

The ipsilateral motor cortex contributes to cross‐limb transfer of performance gains after ballistic motor practice
M Lee, MR Hinder, SC Gandevia… - The Journal of …, 2010 - Wiley Online Library
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 …

Where one hand meets the other: limb-specific and action-dependent movement plans decoded from preparatory signals in single human frontoparietal brain areas
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 …
