Discriminability of Single and Multichannel Intracortical Microstimulation within Somatosensory Cortex

Frontiers in Bioengineering and Biotechnology, 2016
The addition of tactile and proprioceptive feedback to neuroprosthetic limbs is expected to significantly improve the control of these devices. Intracortical microstimulation (ICMS) of somatosensory cortex is a promising method of delivering this ...

A Tac1‐Expressing Brainstem Pathway Underlies the Pathogenesis of Trigeminal Neuralgia

Advanced Science, EarlyView.
A critical TG‐Sp5CTac1‐PBNTac1 pathway drives trigeminal neuropathic pain (TNP). Tac1‐expressing parabrachial nucleus (PBNTac1) neurons exhibit heightened responses to innocuous stimuli in TNP, and chemogenetic inhibition of these neurons effectively prevents TNP development.

Sensory gating, inhibition control and gamma oscillations in the human somatosensory cortex

Scientific Reports, 2016
Inhibiting the responses to irrelevant stimuli is an essential component of human cognitive function. Pre-attentive auditory sensory gating (SG), an attenuated neural activation to the second identical stimulus, has been found to be related to the ...

Brain‐Adhesive Bioelectronics With Shape‐Morphable and Biodegradable Properties for Stable Brain Signal Monitoring

Advanced Science, EarlyView.
A brain‐adhesive sensor (B‐Sensor) was developed by integrating a self‐healing biodegradable elastomer, a tissue‐adhesive hydrogel, and molybdenum electrodes. The B‐Sensor adheres to brain tissue, conforms to cortical curvatures, and maintains stable electrical performance over the intended period for reliable recording of spatiotemporal brain activity

Cortical Somatostatin Neurons Regulate Seizure Susceptibility via MINAR1/Gαs–cAMP Signaling

Advanced Science, EarlyView.
Our study identifies MINAR1 as a novel regulator of cortical interneuron excitability and seizure susceptibility. MINAR1 is preferentially expressed in SST+ interneurons. Genetic ablation of MINAR1 leads to seizure hypersensitivity, reduced SST+ neuron excitability, and impaired Gαs–cAMP signaling, disrupting the E/I balance.

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 ...

Multimodal Layer‐Crossing Interrogation of Brain Circuits Enabled by Microfluidic Axialtrodes

Advanced Science, EarlyView.
The study introduces a flexible microfluidic axialtrode that integrates optical, electrical, and chemical modalities within a single polymer fiber. By redistributing electrodes and fluidic channels along the fiber axis via angled cleaving, it enables simultaneous optogenetic stimulation, electrophysiological recording, and drug delivery across brain ...

Prefrontal cortex and somatosensory cortex in tactile crossmodal association: an independent component analysis of ERP recordings. [PDF]

PLoS ONE, 2007
Our previous studies on scalp-recorded event-related potentials (ERPs) showed that somatosensory N140 evoked by a tactile vibration in working memory tasks was enhanced when human subjects expected a coming visual stimulus that had been paired with the ...
