Classification of Tactile Perception and Attention on Natural Textures from EEG Signals [PDF]

arXiv, 2020
Brain-computer interface allows people who have lost their motor skills to control robot limbs based on electroencephalography. Most BCIs are guided only by visual feedback and do not have somatosensory feedback, which is an important component of normal motor behavior.

A Flexible‐Substrate 5‐µm‐Diameter Needle Electrode: Minimizing Neuronal Death and Enabling Year‐Long Neural Recording

Advanced Materials Interfaces, EarlyView.
An electrophysiological recording technology that uses a 5‐µm‐diameter microneedle electrode device is presented. Due to the remarkable small dimension of the microneedle, the electrode provides minimal invasive neural recording in a mouse brain and enables long‐term recording exceeding the year‐long duration.

MicroRNA binding site variation is enriched in psychiatric disorders

Human Mutation, Volume 43, Issue 12, Page 2153-2169, December 2022., 2022
Abstract Psychiatric disorders have a polygenic architecture, often associated with dozens or hundreds of independent genomic loci. Most associated loci impact noncoding regions of the genome, suggesting that the majority of disease heritability originates from the disruption of regulatory sequences.

Ultra‐Flexible µ‐ECoG Arrays Based on PEDOT:PSS Micropillars

Advanced Materials Interfaces, EarlyView.
This work demonstrates an efficient procedure for fabricating ultra‐flexible neural interfaces endowed with micropatterned microelectrodes to increase surface area and characterized by extremely low impedance values to enable high‐quality recordings. The home‐built device has been shown to record somatosensory evoked potentials in vivo with exceptional

Fingolimod increases parvalbumin-positive neurons in adult mice

IBRO Neuroscience Reports, 2022
In recent years, it has been shown that central nervous system agents, such as antidepressants and antiepileptic drugs, reopen a critical period in mature animals.

Neural Plasticity and Hearing‐Speech Development in Children with Auditory Brainstem Implants for Congenital Hearing Loss Due to Severe Inner Ear Malformation

Advanced Science, EarlyView.
Data from a prospective cohort with 112 auditory brainstem implant users are analyzed. Younger age at implantation (<3 years), less severe inner‐ear malformation (common cavity, cochlear aplasia, and hypoplasia), and more intraoperative eABR evoked electrodes (≥60%) are associated with better hearing and speech outcomes.

Research on Event-Related Desynchronization of Motor Imagery and Movement Based on Localized EEG Cortical Sources [PDF]

This study investigates event-related desynchronization (ERD) phenomena during motor imagery and actual movement. Using sLORETA software, we analyzed the cortical current source density distributions in Mu and Beta frequency bands for 33 subjects during rest, motor imagery, and actual movement conditions. The results were normalized for analysis. Using

Sensory Encoding Alternates With Hippocampal Ripples across Cycles of Forebrain Spiking Cascades

Advanced Science, EarlyView.
This study reveals widespread, coordinated brain activity during passive visual stimulation in mice. Sensory coding, phase‐locked with the periodic dynamics, shows an inverse relationship to hippocampal ripples. The results suggest that periodic brain activity spurs alteration between two distinct operational modes of brain, facilitating exteroceptive ...

Investigating the effects of excitatory and inhibitory somatosensory rTMS on somatosensory functioning in the acute and subacute phases of stroke: a preliminary double-blind and randomized trial

Frontiers in Human Neuroscience
BackgroundRepetitive transcranial magnetic stimulation (rTMS) targeting the primary somatosensory cortex (S1) has a potential effect on somatosensory functioning following a stroke.

Somatosensation Evoked by Cortical Surface Stimulation of the Human Primary Somatosensory Cortex

Frontiers in Neuroscience, 2019
Electrical stimulation of the primary somatosensory cortex using intracranial electrodes is crucial for the evocation of artificial somatosensations, typically tactile sensations associated with specific regions of the body, in brain-machine interface ...
