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

open access: yesJournal 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.

Encoding of Touch Intensity But Not Pleasantness in Human Primary Somatosensory Cortex

open access: yesJournal of Neuroscience, 2016
Growing interest in affective touch has delineated a neural network that bypasses primary somatosensory cortex (S1). Several recent studies, however, have cast doubt on the segregation of touch discrimination and affect, suggesting that S1 also encodes ...

From Rigid to Soft Robotic Approaches for Neuroendoscopy

open access: yesAdvanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

The role of self-touch experience in the formation of the self [PDF]

open access: yes, 2017
The human self has many facets: there is the physical body and then there are different concepts or representations supported by processes in the brain such as the ecological, social, temporal, conceptual, and experiential self.

Discriminability of Single and Multichannel Intracortical Microstimulation within Somatosensory Cortex

open access: yesFrontiers 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 ...

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

Excitability of the motor cortex in patients with migraine changes with the time elapsed from the last attack [PDF]

open access: yes, 2017
BACKGROUND: Motor-evoked potentials (MEPs) produced by single-pulse transcranial magnetic stimulation (TMS) of the motor cortex can be an objective measure of cortical excitability.

Transplantation of GABAergic Interneuron Progenitors Restores Cortical Circuit Function in an Alzheimer's Disease Mouse Model

open access: yesAdvanced Science, EarlyView.
Transplantation of medial ganglionic eminence (MGE) interneuron progenitors into APP/PS1 cortices restored the slow oscillation characteristic of Alzheimer's disease. Donor cells survived, migrated, and matured into functional GABAergic interneurons, forming synaptic connections.

Cortical pain responses in human infants [PDF]

open access: yes, 2006
Despite the recent increase in our understanding of the development of pain processing, it is still not known whether premature infants are capable of processing pain at a cortical level.

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

open access: yesScientific 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 ...
