The Flail Limb Syndrome

Muscle &Nerve, Volume 74, Issue 2, Page 281-292, August 2026.
ABSTRACT The flail limb syndrome is primarily a lower motor neuron disorder that initially affects proximal arm muscles (flail arm syndrome—FAS) or distal leg muscles (flail leg syndrome—FLS). Both were recognized early on (1886 for FAS and 1918 for FLS) as somewhat distinct from classic amyotrophic lateral sclerosis (ALS).

Feedforward motor information enhances somatosensory responses and sharpens angular tuning of rat S1 barrel cortex neurons

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).

Advancing Treatment of Degenerative Eye Diseases at the Nanoscale

Smart Medicine, Volume 5, Issue 4, August 2026.
Nanotherapeutics possess the potential to overcome longstanding bottlenecks in treating degenerative ophthalmic diseases. With a highly tunable surface chemistry, nanotechnology platforms can be customized to navigate specific anatomical barriers in the eye and target pathways of diseases.

Barrel cortex VIP/ChAT interneurons suppress sensory responses in vivo.

PLoS Biology, 2020
Cortical interneurons expressing vasoactive intestinal polypeptide (VIP) and choline acetyltransferase (ChAT) are sparsely distributed throughout the neocortex, constituting only 0.5% of its neuronal population. The co-expression of VIP and ChAT suggests

Increases in the numerical density of GAT-1 positive puncta in the barrel cortex of adult mice after fear conditioning.

PLoS ONE, 2014
Three days of fear conditioning that combines tactile stimulation of a row of facial vibrissae (conditioned stimulus, CS) with a tail shock (unconditioned stimulus, UCS) expands the representation of "trained" vibrissae, which can be demonstrated by ...

Substitution of natural sensory input by artificial neurostimulation of an amputated trigeminal nerve does not prevent the degeneration of basal forebrain cholinergic circuits projecting to the somatosensory cortex

Frontiers in Cellular Neuroscience, 2014
Peripheral deafferentation downregulates acetylcholine (ACh) synthesis in sensory cortices. However the responsible neural circuits and processes are not known.

High serotonin levels during brain development alter the structural input-output connectivity of neural networks in the rat somatosensory layer IV

Frontiers in Cellular Neuroscience, 2013
Homeostatic regulation of serotonin (5-HT) concentration is critical for normal topographical organization and development of thalamocortical (TC) afferent circuits. Down-regulation of the serotonin transporter (SERT) and the consequent impaired reuptake

Non-homogeneous spatial configuration of vibrissae cortical representation in layer IV of the barrel somatosensory cortex

Biological Research, 2008
In the present experiments we studied exclusive and overlapping cortical representational áreas of the vibrissae in layer IV cells, across the entire barrel subfield of the rat somatosensory cortex, looking for evidences that would challenge the present ...

Restoration of Intracortical and Thalamocortical Circuits after Transplantation of Bone Marrow Mesenchymal Stem Cells into the Ischemic Brain of Mice

Cell Transplantation, 2013
Transplantation of bone marrow mesenchymal stem cells (BMSCs) provides a promising regenerative medicine for stroke. Whether BMSC therapy could repair ischemia-damaged neuronal circuits and recover electrophysiological activity has largely been unknown ...
