The encoding of proprioceptive inputs in the brain: knowns and unknowns from a robotic perspective [PDF]

arXiv, 2016
Somatosensory inputs can be grossly divided into tactile (or cutaneous) and proprioceptive -- the former conveying information about skin stimulation, the latter about limb position and movement. The principal proprioceptors are constituted by muscle spindles, which deliver information about muscle length and speed.

Chimera in a neuronal network model of the cat brain [PDF]

, 2016
Neuronal systems have been modeled by complex networks in different description levels. Recently, it has been verified that networks can simultaneously exhibit one coherent and other incoherent domain, known as chimera states. In this work, we study the existence of chimera states in a network considering the connectivity matrix based on the cat ...

Activation of Glutamatergic Neurons in the Supramammillary Nucleus Promotes the Recovery of Consciousness under Sevoflurane Anesthesia

Advanced Science, EarlyView.
Selective lesioning of SuM glutamatergic neurons promoted the induction of and delayed emergence from sevoflurane anesthesia and increased sevoflurane sensitivity. Optogenetic stimulation of SuM glutamatergic neurons or the SuM‐MS projection promoted behavioral arousal and cortical activation under steady‐state sevoflurane anesthesia and reduced the ...

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 ...

Prefrontal cortex and somatosensory cortex in tactile crossmodal association: an independent component analysis of ERP recordings. [PDF]

PLoS ONE, 2007
Our previous studies on scalp-recorded event-related potentials (ERPs) showed that somatosensory N140 evoked by a tactile vibration in working memory tasks was enhanced when human subjects expected a coming visual stimulus that had been paired with the ...

Simultaneous Monitoring of Tyrosinase and ATP in Thick Brain Tissues Using a Single Two‐Photon Fluorescent Probe

Advanced Science, EarlyView.
A single dual‐emission two‐photon fluorescent probe is designed for simultaneously tracking tyrosinase (TYR) and adenosine triphosphate (ATP). With the help of this probe, the intricate correlation and regulatory mechanism between TYR and ATP during oxidative stress is uncovered.

Neural Patterns of Social Pain in the Brain‐Wide Representations Across Social Contexts

Advanced Science, EarlyView.
Empathy arises from both physiological and social pain, yet their shared and context‐specific neural mechanisms remain unclear. Combining fMRI and multivariate pattern analysis, this study decodes overlapping empathy networks and distinct representations for social exclusion versus separation.

Vascular Gap Junctions Contribute to Forepaw Stimulation-Induced Vasodilation Differentially in the Pial and Penetrating Arteries in Isoflurane-Anesthetized Rats

Frontiers in Molecular Neuroscience, 2018
Somatosensory stimulation causes dilation of the pial and penetrating arteries and an increase in cerebral blood flow (CBF) in the representative region of the somatosensory cortex. As an underlying mechanism for such stimulation-induced increases in CBF,

The homunculus for proprioception: Toward learning the representation of a humanoid robot's joint space using self-organizing maps [PDF]

Proceedings of the 2019 Joint IEEE 9th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob), Engineer's House Conference Centre, Oslo, Norway, August 19-22, 2019, pp. 113-114, 2019
In primate brains, tactile and proprioceptive inputs are relayed to the somatosensory cortex which is known for somatotopic representations, or, "homunculi". Our research centers on understanding the mechanisms of the formation of these and more higher-level body representations (body schema) by using humanoid robots and neural networks to construct ...

The Lung Microbiome Modulates Pain‐Like Behavior Via the Lung–Brain Axis in a Nitroglycerin‐Induced Chronic Migraine Mouse Model

Advanced Science, EarlyView.
Intratracheal neomycin alters pulmonary microbiota, activating the vagus nerve via lung brain‐derived neurotrophic factor/tropomyosin receptor kinase B (BDNF/TrkB) pathway, further projecting to nucleus of solitary tract (NTS), then dorsal raphe nucleus (DRN), where activated serotoninergic neurons increase brain serotonin, alleviating migraine.
