Diminished Signal‐to‐Noise Ratio Disrupts Somatosensory Population Encoding and Drives Tactile Hyposensitivity in the Fmr1−/y Autism Model

Advanced Science, EarlyView.
This study provides a translational approach for linking neural activity to tactile deficits in autism. By combining psychophysics with cortical recordings in a mouse model of autism, we show that low signal‐to‐noise ratio in somatosensory neurons weakens population encoding of fine touch, impairing detection, decoding, and leading to perceptual ...

Motor and Somatosensory Evoked Potential Monitoring Without Wakeup Test during Scoliosis Surgery

Journal of Rawalpindi Medical College, 2019
Background: Available evidence suggests that Transcranial electric motor evoked potentials and somatosensory evoked potential are safe methods to check the integrity of the spinal cord during spine deformity correction surgery. We compare the efficacy of

Adults on the autism spectrum differ from neurotypical peers when self-generating but not passively-experiencing somatosensation: a high-density electrophysiological (EEG) mapping and virtual reality study

NeuroImage
Little is known about how different features of tactile inputs affect somatosensory perception in autism. In this study we combined high-density electroencephalography (EEG) and virtual reality (VR) to assess how the volition and pattern consistency of ...

Multimodal evoked potential abnormalities in patients with Wilson's disease [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2005
The aim of this study was to investigate the involvement of the following functional systems: somatosensory evoked potentials (SSEP), visual evoked potentials (VEP), and event related potentials (ERP), in twenty patients with Wilson's disease (WD).

Tactile spatial attention enhances gamma-band activity in somatosensory cortex and reduces low-frequency activity in parieto-occipital areas. [PDF]

, 2006
We investigated the effects of spatial-selective attention on oscillatory neuronal dynamics in a tactile delayed-match-to-sample task. Whole-head magnetoencephalography was recorded in healthy subjects while dot patterns were presented to their index ...

Excitatory postsynaptic potentials in rat neocortical neurons in vitro. III. Effects of a quinoxalinedione non-NMDA receptor antagonist [PDF]

, 1990
1. Intracellular microelectrodes were used to obtain recordings from neurons in layer II/III of rat frontal cortex. A bipolar electrode positioned in layer IV of the neocortex was used to evoke postsynaptic potentials.

Circular RNA circNrip1 Interacts with SYNCRIP to Promote Neuropathic Pain by Stabilizing Tlr2 mRNA in Primary Sensory Neurons

Advanced Science, EarlyView.
Model of circNrip1 (cNrip1) upregulation driving neuropathic pain mechanisms. After peripheral nerve injury, increased FUS triggers the formation and upregulation of cNrip1 in injured DRG neurons. Upregulated cNrip1 recruits SYNCRIP to the 3′‐UTR of Tlr2 mRNA by binding to both, thereby promoting SYNCRIP‐triggered Tlr2 mRNA stability and increasing ...

DIAGNOSTIC VALUE OF SOMATOSENSORY EVOKED POTENTIALS IN CERVICAL MYELOPATHY

The Iraqi Journal of Medical Sciences, 2016
Background:Cervical myelopathy is a condition caused by narrowing of the spinal canal leading to cord dysfunction. The most common causes are congenital stenosis and degenerative stenosis caused by spondylosis.

Non-parametric statistical thresholding for sparse magnetoencephalography source reconstructions. [PDF]

, 2012
Uncovering brain activity from magnetoencephalography (MEG) data requires solving an ill-posed inverse problem, greatly confounded by noise, interference, and correlated sources.

Mild Focal Cooling Decouples Dendrites to Reconfigure Cortical Output

Advanced Science, EarlyView.
Mild cooling of the cortical surface selectively modulates apical dendritic excitability, plasticity, and somato‐dendritic coupling, while uncoupling these effects from basal dendrites, and reshapes apical‐driven responses in barrel cortex during whisker touch.
