Micro‐Coil Neuromodulation at Single‐Cell and Circuit Levels for Inhibiting Natural Neuroactivity, Neutralizing Electric Neural Excitation, and Suppressing Seizures

Advanced Science, EarlyView.
Micromagnetic stimulation (µMS) offers a precise method for neural inhibition, complementing existing neuromodulation techniques. Using an implantable micro‐coil device, µMS selectively suppresses cortical activity with high spatial resolution. It effectively counteracts micro‐electrode stimulation and reduces seizure amplitude, highlighting its ...

IFITM2 Modulates Endocytosis Maintaining Neural Stem Cells in Developing Neocortex

Advanced Science, EarlyView.
This study reveals IFITM2 as a key regulator of endocytosis in radial glial cells (RGCs) during brain development. IFITM2's YXXø motif and phosphoinositide‐binding residues (K82/K87) are essential for endosome formation. IFITM2 deficiency disrupts the embryonic cortical neurogenesis, revealing a conserved mechanism linking endocytic dynamics to neural ...

Cell class-specific long-range axonal projections of neurons in mouse whisker-related somatosensory cortices

eLife
Long-range axonal projections of diverse classes of neocortical excitatory neurons likely contribute to brain-wide interactions processing sensory, cognitive and motor signals.

In‐Sensor Computing‐Based Smart Sensing Architecture Implemented Using a Dual‐Gate Metal‐Oxide Thin‐Film Transistor Technology

Advanced Electronic Materials, EarlyView.
A smart sensor architecture combining an array of sensing elements with an overlapping array of computing and memory elements thus emulates an innervated peripheral sensing system (IPSS) capable of local and autonomous neuromorphic in‐sensor data pre‐processing is presented. Compatibility of the proposed architecture with functionally distinct elements

Effect of Prenatal Valproic Acid Exposure on Cortical Morphology in Female Mice

Journal of Pharmacological Sciences, 2012
We have recently shown that prenatal valproic acid (VPA) exposure causes autism spectrum disorders–like behavioral abnormalities and Nissl-positive cell loss in both prefrontal and somatosensory cortices in male mice.

Difference in cortical activation during use of volar and dorsal hand splints: a functional magnetic resonance imaging study

Neural Regeneration Research, 2016
There have been no studies reported on the difference in cortical activation during use of volar and dorsal hand splints. We attempted to investigate the difference in cortical activation in the somatosensory cortical area during use of volar and dorsal ...

Invariant Neuromorphic Representations of Tactile Stimuli Improve Robustness of a Real‐Time Texture Classification System

Advanced Intelligent Systems, EarlyView.
This work presents a method to create neuron‐like (neuromorphic) spiking representations of texture that are invariant to the scanning speed and contact force applied in the tactile sensing process. In offline and real‐time experiments, these representations improve classification accuracy, computational efficiency, and the ability to identify textures

Vestibular and cochlear dysfunction in aging: Two sides of the same coin?

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 8, Issue 4, Page 308-314, December 2022., 2022
Abstract Objective Nonspecific complaints of hearing loss, vertigo, imbalance, and instability, without a defined etiology, are very prevalent in the elderly population, with a great impact on morbidity and mortality in this age group. The objectives of this study were to verify whether there is age‐related vestibular dysfunction and to test the ...

Evolution of somatosensory and motor cortex in primates [PDF]

The Anatomical Record Part A: Discoveries in Molecular, Cellular, and Evolutionary Biology, 2004
AbstractInferences about how the complex somatosensory systems of anthropoid primates evolved are based on comparative studies of such systems in extant mammals. Experimental studies of members of the major clades of extant mammals suggest that somatosensory cortex of early mammals consisted of only a few areas, including a primary area, S1, bordered ...

Decoding hand kinematics from population responses in sensorimotor cortex during grasping [PDF]

arXiv, 2019
The hand, a complex effector comprising dozens of degrees of freedom of movement, endows us with the ability to flexibly, precisely, and effortlessly interact with objects. The neural signals associated with dexterous hand movements in primary motor cortex (M1) and somatosensory cortex (SC) have received comparatively less attention than have those ...
