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

Decoding visual object categories in early somatosensory cortex [PDF]
Neurons, even in the earliest sensory areas of cortex, are subject to a great deal of contextual influence from both within and across modality connections. In the present work, we investigated whether the earliest regions of somatosensory cortex (S1 and

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.

Neural Modeling and Imaging of the Cortical Interactions Underlying Syllable Production [PDF]
This paper describes a neural model of speech acquisition and production that accounts for a wide range of acoustic, kinematic, and neuroimaging data concerning the control of speech movements. The model is a neural network whose components correspond to

SYNAPTIC PLASTICITY IN THE SOMATOSENSORY CORTEX
The term synaptic plasticity implies modification in the strength or efficacy of synaptic transmission between pre-existing synapses. Long-term changes in synaptic efficacy have been widely proposed as the cellular mechanism of the learning and memory machineries of the brain.

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

Large-scale changes in cortical dynamics triggered by repetitive somatosensory electrical stimulation. [PDF]
BackgroundRepetitive somatosensory electrical stimulation (SES) of forelimb peripheral nerves is a promising therapy; studies have shown that SES can improve motor function in stroke subjects with chronic deficits.

Monosynaptic connections between pairs of spiny stellate cells in layer 4 and pyramidal cells in layer 5A indicate that lemniscal and paralemniscal afferent pathways converge in the infragranular somatosensory cortex. [PDF]
Monosynaptic interlaminar connections between spiny stellate cells in layer 4 (L4), the main cortical recipient layer for thalamic projections, and pyramidal cells in layer 5A (L5A), one of the main cortical output layers, were examined anatomically and ...

Frequency Specific Modulation of Human Somatosensory Cortex [PDF]
Oscillatory neuronal activities are commonly observed in response to sensory stimulation. However, their functional roles are still the subject of debate. One-way to probe the roles of oscillatory neural activities is to deliver alternating current to the cortex at biologically relevant frequencies and examine whether such stimulation influences ...
