Somatosensory cortex participates in the consolidation of human motor memory.

PLoS Biology, 2019
Newly learned motor skills are initially labile and then consolidated to permit retention. The circuits that enable the consolidation of motor memories remain uncertain.

Inhibition of the primary motor cortex and the upgoing thumb sign

eNeurologicalSci, 2017
Background: The upgoing thumb sign has been frequently observed in patients with minor strokes and transient ischemic attacks as an indicator of brain involvement.

Partially Overlapping Sensorimotor Networks Underlie Speech Praxis and Verbal Short-Term Memory: Evidence from Apraxia of Speech Following Acute Stroke

Frontiers in Human Neuroscience, 2014
We tested the hypothesis that motor planning and programming of speech articulation and verbal short-term memory (vSTM) depend on partially overlapping networks of neural regions. We evaluated this proposal by testing 76 individuals with acute ischemic

Functional specificity of human premotor-motor cortical interactions during action selection [PDF]

, 2007
Functional connections between dorsal premotor cortex (PMd) and primary motor cortex (M1) have been revealed by paired-pulse transcranial magnetic stimulation (TMS).

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.

Cholecystokinin facilitates motor skill learning by modulating neuroplasticity in the motor cortex

eLife
Cholecystokinin (CCK) is an essential modulator for neuroplasticity in sensory and emotional domains. Here, we investigated the role of CCK in motor learning using a single pellet reaching task in mice.

Prefrontal cortical thickness in motor neuron disease

NeuroImage: Clinical, 2018
Objective: To examine whether the distribution of prefrontal cortical thickness in patients with motor neuron disease is normal or bimodal and how it compares to the normal population.

Evaluation of Relationships between Corticospinal Excitability and Somatosensory Deficits in the Acute and Subacute Phases of Stroke

Journal of Integrative Neuroscience, 2023
Background: Somatosensory deficits are common symptoms post stroke. Repetitive transcranial magnetic stimulation (rTMS) over the motor cortex is able to promote motor rehabilitation, whereby its impact on somatosensory functioning remains unknown.
