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

open access: yes, 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 ...

Spread of epileptiform activity in the immature rat neocortex studied with voltage-sensitive dyes and laser scanning microscopy [PDF]

open access: yes, 1994
1. Adult rats and rats with a postnatal age of 3-29 days (PN 3-29) were used for the preparation of in vitro slices of the frontal neocortex. Epileptiform activity was induced by bath application of the gamma-aminobutyric acid-A (GABAA) receptor ...

Inroads into epilepsy through high‐frequency oscillations: Achievements and benchmark areas for improvement

open access: yesEpilepsia, EarlyView.
Abstract High‐frequency oscillations (HFOs) were discovered more than 20 years ago, and since then they have been studied intensively in the context of epilepsy. HFOs encompass a broad spectrum of oscillations, typically ranging from 80 Hz to several kHz, that include both normal and pathological oscillations, documented in people with epilepsy and ...

Variability in non-invasive brain stimulation studies: reasons and results [PDF]

open access: yes, 2018
Non-invasive brain stimulation techniques (NIBS), such as Theta Burst Stimulation (TBS), Paired Associative Stimulation (PAS) and transcranial Direct Current Stimulation (tDCS), are widely used to probe plasticity in the human motor cortex (M1). Although

Long‐lasting remodeling of astrocytes in an Scna1+/− mouse model of Dravet syndrome

open access: yesEpilepsia, EarlyView.
Abstract Objective Dravet syndrome (DS) is a prototypical developmental and epileptic encephalopathy caused by mutations in the SCN1A gene, leading to loss of function of the voltage‐gated sodium channel Naᵥ1.1. The latter causes early onset drug‐resistant seizures and enduring cognitive and behavioral deficits.

Effects of General Anesthesia with Propofol on Thalamocortical Sensory Processing in Rats

open access: yesJournal of Pharmacological Sciences, 2014
.: The effects of anesthetics on the transmission and processing of sensory information within the thalamocortical pathway and the underlying mechanism are not fully understood.

Altered stimulus frequency and intensity dependence of the somatosensory evoked potential in rats after acute application of two mitochondrial toxins [PDF]

open access: yes, 2009
Mitochondrial toxins are a special group of toxicants with nervous system ef TRACT - fects. The resulting nervous system damage could be detected and followed-up by means of functional biomarkers but these still have to be worked out.

Pediatric sensorimotor cortical responsiveness to intracerebral stimulation during stereoelectroencephalographic monitoring: Age effects and area specificity

open access: yesEpilepsia, EarlyView.
Abstract Objective This study was undertaken to determine how age influences clinical responsiveness to intracerebral electrical stimulation (IES) in children across primary and secondary sensorimotor cortices and to assess age effects on response complexity and area‐specific responsiveness.

Creativity and its link to epilepsy

open access: yesEpilepsia Open, EarlyView.
Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our

Somatosensory evoked potential monitoring for position-related brachial plexus injury during cerebellopontine angle tumor resection: A retrospective cohort study

open access: yesJournal of International Medical Research
Objective To evaluate the utility of intraoperative somatosensory evoked potential monitoring for detecting position-related brachial plexus injury during cerebellopontine angle tumor resection, identify independent risk factors, and assess the ...
