Task-free functional MRI in cervical dystonia reveals multi-network changes that partially normalize with botulinum toxin. [PDF]

open access: yesPLoS ONE, 2013
Cervical dystonia is characterized by involuntary, abnormal movements and postures of the head and neck. Current views on its pathophysiology, such as faulty sensorimotor integration and impaired motor planning, are largely based on studies of focal hand

Neuroplasticity of the Sensorimotor Cortex during Learning [PDF]

open access: yesNeural Plasticity, 2011
We will discuss some of the current issues in understanding plasticity in the sensorimotor (SM) cortices on the behavioral, neurophysiological, and synaptic levels. We will focus our paper on reaching and grasping movements in the rat. In addition, we will discuss our preliminary work utilizing inhibition of protein kinase Mζ (PKMζ), which has recently

Cortical presynaptic control of dorsal horn C-afferents in the rat. [PDF]

open access: yesPLoS ONE, 2013
Lamina 5 sensorimotor cortex pyramidal neurons project to the spinal cord, participating in the modulation of several modalities of information transmission.

Human Sensorimotor Cortex Represents Conflicting Visuomotor Mappings [PDF]

open access: yesThe Journal of Neuroscience, 2013
Behavioral studies have shown that humans can adapt to conflicting sensorimotor mappings that cause interference after intensive training. While previous research works indicate the involvement of distinct brain regions for different types of motor learning (e.g., kinematics vs dynamics), the neural mechanisms underlying joint adaptation to conflicting

Disrupted functional connectivity between sub-regions in the sensorimotor areas and cortex in migraine without aura

open access: yesThe Journal of Headache and Pain, 2020
Background Migraine is a severe and disabling brain disorder, and the exact neurological mechanisms remain unclear. Migraineurs have altered pain perception, and headache attacks disrupt their sensory information processing and sensorimotor integration ...

Electrocortical Dynamics of Usual Walking and the Planning to Step over Obstacles in Parkinson’s Disease

open access: yesSensors, 2023
The neural correlates of locomotion impairments observed in people with Parkinson’s disease (PD) are not fully understood. We investigated whether people with PD present distinct brain electrocortical activity during usual walking and the approach phase ...

Dreamed Movement Elicits Activation in the Sensorimotor Cortex [PDF]

open access: yesCurrent Biology, 2011
Since the discovery of the close association between rapid eye movement (REM) sleep and dreaming, much effort has been devoted to link physiological signatures of REM sleep to the contents of associated dreams [1-4]. Due to the impossibility of experimentally controlling spontaneous dream activity, however, a direct demonstration of dream contents by ...

Reduction in Phencyclidine Induced Sensorimotor Gating Deficits in the Rat Following Increased System Xc − Activity in the Medial Prefrontal Cortex [PDF]

open access: yes, 2013
Rationale: Aspects of schizophrenia, including deficits in sensorimotor gating, have been linked to glutamate dysfunction and/or oxidative stress in the prefrontal cortex. System xc −, a cystine–glutamate antiporter, is a poorly understood mechanism that

Baby steps: investigating the development of perceptual-motor couplings in infancy [PDF]

open access: yes, 2014
There are cells in our motor cortex that fire both when we perform and when we observe similar actions. It has been suggested that these perceptual-motor couplings in the brain develop through associative learning during correlated sensorimotor ...

Cortex integrity relevance in muscle synergies in severe chronic stroke

open access: yesFrontiers in Human Neuroscience, 2014
Background: Recent experimental evidence has indicated that the motor system coordinates muscle activations through a linear combination of muscle synergies that are specified at the spinal or brainstem networks level.
