An electrocorticographic brain interface in an individual with tetraplegia. [PDF]

open access: yesPLoS ONE, 2013
Brain-computer interface (BCI) technology aims to help individuals with disability to control assistive devices and reanimate paralyzed limbs. Our study investigated the feasibility of an electrocorticography (ECoG)-based BCI system in an individual with

Evolution of object identity information in sensorimotor cortex throughout grasp [PDF]

open access: yesNature Communications
Reaching for and grasping an object seems a continuous process, yet somatosensory signals undergo dramatic state changes near the time of object contact.

Redefining borders in the sensorimotor cortex [PDF]

open access: yeseLife
Experiments mapping individual neurons in the sensorimotor cortex of mice show that sharp transitions in functional properties can define cortical regions.

Bihemispheric sensorimotor oscillatory network states determine cortical responses to transcranial magnetic stimulation

open access: yesBrain Stimulation, 2022
Background: Brain responses to external stimuli vary with fluctuating states of neuronal activity. Previous work has demonstrated effects of phase and power of the ongoing local sensorimotor μ-alpha-oscillation on responses to transcranial magnetic ...

Beta Peak Frequencies at Rest Correlate with Endogenous GABA+/Cr Concentrations in Sensorimotor Cortex Areas. [PDF]

open access: yesPLoS ONE, 2016
Neuronal oscillatory activity in the beta band (15-30 Hz) is a prominent signal within the human sensorimotor cortex. Computational modeling and pharmacological modulation studies suggest an influence of GABAergic interneurons on the generation of beta ...

Differential grey matter changes in sensorimotor cortex related to exceptional fine motor skills. [PDF]

open access: yesPLoS ONE, 2012
Functional changes in sensorimotor representation occur in response to use and lesion throughout life. Emerging evidence suggests that functional changes are paralleled by respective macroscopic structural changes.

Age‐related decline in cortical inhibitory tone strengthens motor memory

open access: yesNeuroImage, 2021
Ageing disrupts the finely tuned excitation/inhibition balance (E:I) across cortex via a natural decline in inhibitory tone (γ-amino butyric acid, GABA), causing functional decrements.

Altered Functional Segregated Sensorimotor, Associative, and Limbic Cortical-Striatal Connections in Parkinson's Disease: An fMRI Investigation

open access: yesFrontiers in Neurology, 2021
Multiple studies have identified segregated functional territories in the basal ganglia for the control of goal-directed and habitual actions. It has been suggested that in PD, preferential loss of dopamine in the posterior putamen may cause a major ...

Sensorimotor organization in double cortex syndrome [PDF]

open access: yesHuman Brain Mapping, 2005
AbstractSubcortical band heterotopia is a diffuse malformation of cortical development related to pharmacologically intractable epilepsy. On magnetic resonance imaging (MRI), patients with “double cortex” syndrome (DCS) present with a band of heterotopic gray matter separated from the overlying cortex by a layer of white matter.

Salience network functional connectivity is spatially heterogeneous across sensorimotor cortex in healthy humans

open access: yesNeuroImage, 2020
The salience network is responsive during a range of conditions requiring immediate behavioral responses, including pain processing. Resting-state functional connectivity of the salience network to the sensorimotor cortex is altered in chronic pain ...
