Mapping of the Motor Cortex [PDF]

Cureus, 2020
The resection of brain tumors located within or near the eloquent tissue has a higher risk of postoperative neurological deficits. The primary concerns include loss of sensory and motor functions in the contralateral face, upper and lower extremities, as well as speech deficits.

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 ...

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.

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 cortical ...

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 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.

Sensory and motor electrophysiological mapping of the cerebellum in humans [PDF]

Scientific Reports, 2020
Abstract Damage to the cerebellum during posterior fossa surgery can lead to ataxia and in paediatric cases, the risk of cerebellar mutism syndrome. Animal electrophysiological and human imaging studies have shown compartmentalisation of sensorimotor and cognitive functions within the cerebellum.

MAP 1C is a motor [PDF]

The Journal of Cell Biology, 2006
When the protein dynein was discovered to provide the flagellar bending force to axonemal microtubules (MTs) (Gibbons, 1963), “people had jumped to the reasonable hypothesis that dynein was perhaps also involved in other microtubule movements,” recalls Richard Vallee (Columbia University Medical Center, New York, NY).

Mapping motor representations in the human cerebellum [PDF]

Brain, 2012
The cerebellum is a major motor structure. However, in humans, its efferent topographical organization remains controversial and indirectly inferred from neuroimaging and animal studies. Even central questions such as 'Can we evoke limb movements by stimulating the cerebellar cortex?' have no clear answer.

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.
