Separate areas for mirror responses and agency within the parietal operculum [PDF]

, 2008
There is common neural activity in parietal and premotor cortex when executing and observing goal-directed movements: the “mirror” response. In addition, active and passive limb movements cause overlapping activity in premotor and somatosensory cortex ...

The effects of neck flexion on cerebral potentials evoked by visual, auditory and somatosensory stimuli and focal brain blood flow in related sensory cortices

Journal of Physiological Anthropology, 2012
Background A flexed neck posture leads to non-specific activation of the brain. Sensory evoked cerebral potentials and focal brain blood flow have been used to evaluate the activation of the sensory cortex.

Printing‐Assisted Integration of Thermal, Fluidic and Electrical Components in Implants for Focal Brain Cooling

Advanced Science, EarlyView.
Extrusion‐based 3D printing of silicones and discrete electronic components are combined to create cortical implants for rodents that integrate thermal neuromodulation and electrical recording. Linked to an autonomous auxiliary driver unit, the system enables rapid, stable and localized hypothermia alongside ECoG recording.

Study of EEGs from somatosensory cortex and Alzheimer's disease sources [PDF]

, 2012
This study is to investigate the electroencephalogram (EEG) differences generated from a normal and Alzheimer’s disease (AD) sources. We also investigate the effects of brain tissue distortions due to AD on EEG.

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 ...

Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

Advanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

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 ...
