Mapping grip force to motor networks

NeuroImage, 2021
There is ongoing debate about the role of cortical and subcortical brain areas in force modulation. In a whole-brain approach, we sought to investigate the anatomical basis of grip force whilst acknowledging interindividual differences in connectivity patterns.

Semi-automated motor hotspot search (SAMHS): a framework toward an optimised approach for motor hotspot identification

Frontiers in Human Neuroscience, 2023
BackgroundMotor hotspot identification represents the first step in the determination of the motor threshold and is the basis for the specification of stimulation intensity used for various Transcranial Magnetic Stimulation (TMS) applications.

Robotic transcranial magnetic stimulation motor maps and hand function in adolescents

Physiological Reports, 2021
Introduction Transcranial magnetic stimulation (TMS) motor mapping can characterize the neurophysiology of the motor system. Limitations including human error and the challenges of pediatric populations may be overcome by emerging robotic systems.

Neurochemical changes in basal ganglia affect time perception in parkinsonians

Journal of Biomedical Science, 2018
Background Parkinson’s disease is described as resulting from dopaminergic cells progressive degeneration, specifically in the substantia nigra pars compacta that influence the voluntary movements control, decision making and time perception.

Damage to fronto-parietal networks impairs motor imagery ability after stroke : a voxel-based lesion symptom mapping study [PDF]

, 2016
Background: mental practice with motor imagery has been shown to promote motor skill acquisition in healthy subjects and patients. Although lesions of the common motor imagery and motor execution neural network are expected to impair motor imagery ...

Time perception mechanisms at central nervous system

Neurology International, 2016
The five senses have specific ways to receive environmental information and lead to central nervous system. The perception of time is the sum of stimuli associated with cognitive processes and environmental changes.

Electrophysiologic Mapping of the Extraocular Motor Nuclei [PDF]

Cureus, 2021
Mapping the floor of the fourth ventricle to identify the motonuclei of cranial nerves VII-XII has been well-described. Though there are some reports of stimulating the pontomesencephalic surface to identify the extraocular motor nuclei, there is a debate as to its efficacy and utility in helping to identify safe entry zones for medullary incision in ...

The Effect of Inter-pulse Interval on TMS Motor Evoked Potentials in Active Muscles

Frontiers in Human Neuroscience, 2022
ObjectiveThe time interval between transcranial magnetic stimulation (TMS) pulses affects evoked muscle responses when the targeted muscle is resting. This necessitates using sufficiently long inter-pulse intervals (IPIs). However, there is some evidence

Visual Space Constructed by Saccade Motor Maps [PDF]

Frontiers in Human Neuroscience, 2016
How visual space is represented in the brain is an open question in neuroscience. Embodiment theories propose that spatial perception is structured by neural motor maps. Especially, maps which code the targets for saccadic eye movements contain a precise representation of external space.

Self Organizing Motor Maps for Color-Mapped Image Re-Indexing [PDF]

IEEE Transactions on Image Processing, 2007
Palette re-ordering is an effective approach for improving the compression of color-indexed images. If the spatial distribution of the indexes in the image is smooth, greater compression ratios may be obtained. As is already known, obtaining an optimal re-indexing scheme is not a trivial task.
