Mapping of the preferred direction in the motor cortex [PDF]

Proceedings of the National Academy of Sciences, 2007
Directional tuning is a basic functional property of cell activity in the motor cortex. Previous work has indicated that cells with similar preferred directions are organized in columns perpendicular to the cortical surface. Here we show that these columns are organized in an orderly fashion in the tangential dimension on the ...

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.

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.

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.

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.

Motor recalibration of visual and saccadic maps

Proceedings of the Royal Society B: Biological Sciences, 2023
How does the brain maintain an accurate visual representation of external space? Movement errors following saccade execution provide sufficient information to recalibrate motor and visual space. Here, we asked whether spatial information for vision and saccades is processed in shared or in separate resources.

Genetic influence alters the brain synchronism in perception and timing

Journal of Biomedical Science, 2018
Background Studies at the molecular level aim to integrate genetic and neurobiological data to provide an increasingly detailed understanding of phenotypes related to the ability in time perception.

Axonal mapping of the motor cranial nerves

Frontiers in Neuroanatomy, 2023
Basic behaviors, such as swallowing, speech, and emotional expressions are the result of a highly coordinated interplay between multiple muscles of the head. Control mechanisms of such highly tuned movements remain poorly understood. Here, we investigated the neural components responsible for motor control of the facial, masticatory, and tongue muscles

Motor imagery and its effect on complex regional pain syndrome: an integrative review

Neurology International, 2015
The motor imagery (MI) has been proposed as a treatment in the complex regional pain syndrome type 1 (CRPS-1), since it seems to promote a brain reorganization effect on sensory- motor areas of pain perception.

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
