Emergent Bio-Functional Similarities in a Cortical-Spike-Train-Decoding Spiking Neural Network Facilitate Predictions of Neural Computation [PDF]
arXiv, 2023 Despite its better bio-plausibility, goal-driven spiking neural network (SNN) has not achieved applicable performance for classifying biological spike trains, and showed little bio-functional similarities compared to traditional artificial neural networks.

eLife, 2017 The primary vibrissae motor cortex (vM1) is responsible for generating whisking movements. In parallel, vM1 also sends information directly to the sensory barrel cortex (vS1).

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.

Isoform cell-type specificity in the mouse primary motor cortex [PDF]
Nature, 2020 AbstractFull-length SMART-seq1 single-cell RNA sequencing can be used to measure gene expression at isoform resolution, making possible the identification of specific isoform markers for different cell types. Used in conjunction with spatial RNA capture and gene-tagging methods, this enables the inference of spatially resolved isoform expression for ...

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.

Betz cells of the primary motor cortex
Journal of Comparative NeurologyAbstractBetz cells, named in honor of Volodymyr Betz (1834–1894), who described them as “giant pyramids” in the primary motor cortex of primates and other mammalian species, are layer V extratelencephalic projection (ETP) neurons that directly innervate α‐motoneurons of the brainstem and spinal cord.

Conversion of Sensory Signals into Motor Commands in Primary Motor Cortex [PDF]
The Journal of Neuroscience, 1998 Movement triggered by sensory stimuli requires that the networks generating the motor commands receive an adequate driving input, which, in general, is a transformed version of the initial sensory signal. We investigated the nature of this transformation in a task in which monkeys categorize the speed of tactile stimuli as either low or high, reaching ...

Context-dependent limb movement encoding in neuronal populations of motor cortex
Nature Communications, 2019 Network activity in primary motor cortex (M1) controls dexterous limb movements. Here, the authors show that the M1 population code varies according to contextual motor demands that are conveyed via the secondary motor cortex (M2).

Segmental reorganization of the leg primary motor area
Interdisciplinary Neurosurgery, 2020 Reorganization of eloquent cortex due to neighboring stressors, like tumors and epilepsy, has been previously documented. Here we report reorganization of a subregion of the primary motor cortex due to a slow-growing primary brain tumor.

Frontiers in Human Neuroscience, 2022 Previous studies have shown that changes in gray matter density and volume in the left primary motor cortex are significantly associated with changes in individuals’ verbal intelligence quotient (VIQ), but not with their performance intelligence quotient
