Patterns of myeloarchitecture in lower limb amputees: an MRI study

Frontiers in Neuroscience, 2015
Functional studies of cortical plasticity in humans suggest that the motor cortex reorganizes when the descending motor output pathway is disrupted as a result of limb amputation.

Cell type specific connections from primary motor to primary somatosensory cortex. [PDF]

, 2013
Anatomical studies have shown that primary somatosensory (S1) and primary motor (M1) cortices are reciprocally connected. The pathway from primary motor cortex (M1) to primary somatosensory cortex (S1) is thought to influence activity in S1 by ...

Pain-motor integration in the primary motor cortex in Parkinson's disease [PDF]

Brain Stimulation, 2017
In Parkinson's disease (PD), the influence of chronic pain on motor features has never been investigated. We have recently designed a technique that combines nociceptive system activation by laser stimuli and primary motor cortex (M1) activation through transcranial magnetic stimulation (TMS), in a laser-paired associative stimulation design (Laser-PAS)

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Different modulation of common motor information in rat primary and secondary motor cortices. [PDF]

PLoS ONE, 2014
Rodents have primary and secondary motor cortices that are involved in the execution of voluntary movements via their direct and parallel projections to the spinal cord.

Future spinal reflex is embedded in primary motor cortex output. [PDF]

Sci Adv
Mammals can execute intended limb movements despite the fact that spinal reflexes involuntarily modulate muscle activity. To generate appropriate muscle activity, the cortical descending motor output must coordinate with spinal reflexes, yet the ...

Interregional compensatory mechanisms of motor functioning in progressing preclinical neurodegeneration. [PDF]

, 2013
Understanding brain reserve in preclinical stages of neurodegenerative disorders allows determination of which brain regions contribute to normal functioning despite accelerated neuronal loss.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Prediction of movement intention using connectivity within motor-related network: An electrocorticography study. [PDF]

PLoS ONE, 2018
Most brain-machine interface (BMI) studies have focused only on the active state of which a BMI user performs specific movement tasks. Therefore, models developed for predicting movements were optimized only for the active state.

Involvement of Primary Motor Cortex in Motor Imagery: A Neuromagnetic Study

NeuroImage, 1997
Functional brain imaging studies have indicated that several cortical and subcortical areas active during actual motor performance are also active during imagination or mental rehearsal of movements. Recent evidence shows that the primary motor cortex may also be involved in motor imagery.
