Feasibility of Glutamate and GABA Detection in Pons and Thalamus at 3T and 7T by Proton Magnetic Resonance Spectroscopy

open access: yesFrontiers in Neuroscience, 2020
Glutamate detection in pons and thalamus using proton magnetic resonance spectroscopy (1H-MRS) after an intervention is of interest for studying various brain disorders. However, 1H-MRS in these brain regions is challenging and time-consuming, especially

Sleep and Wakefulness Are Controlled by Ventral Medial Midbrain/Pons GABAergic Neurons in Mice

open access: yesJournal of Neuroscience, 2018
Sleep–wake behavior is controlled by a wide range of neuronal populations in the mammalian brain. Although the ventral midbrain/pons (VMP) area is suggested to participate in sleep–wake regulation, the neuronal mechanisms have remained unclear.

Calcium imaging of sleep–wake related neuronal activity in the dorsal pons

open access: yesNature Communications, 2016
The dorsal pons has long been implicated in the generation of rapid eye movement (REM) sleep, but the underlying circuit mechanisms remain poorly understood.

Technologies for Cost-Effective udWDM-PONs

open access: yesJournal of Lightwave Technology, 2016
New technologies for ultradense WDM-PON (udWDM-PON), enabled by coherent techniques and low-cost devices, are developed for an efficient utilization of the optical spectrum, revealing that the “Wavelength-to-the-User” concept can be feasible.

Identification of proliferative progenitors associated with prominent postnatal growth of the pons

open access: yesNature Communications, 2016
The pons controls crucial sensorimotor and autonomic functions. In humans, it grows sixfold postnatally and is a site of paediatric gliomas; however, the mechanisms of pontine growth remain poorly understood.

Neuropeptide S- and Neuropeptide S receptor-expressing neuron populations in the human pons

open access: yesFrontiers in Neuroanatomy, 2015
Neuropeptide S (NPS) is a regulatory peptide with potent pharmacological effects. In rodents, NPS is expressed in a few pontine cell clusters. Its receptor (NPSR1) is, however, widely distributed in the brain. The anxiolytic and arousal-promoting effects

The Portable Neuromodulation Stimulator (PoNS) for Neurorehabilitation

open access: yes, 2017
The Portable Neuromodulation Stimulator (PoNS) is a compact, self-contained device that delivers a fixed sequence of dc-balanced voltage pulses to the anterior-dorsal tongue through a matrix of 143 gold-plated electrodes.
