Targeting the interaction of GABAB receptors with CaMKII with an interfering peptide restores receptor expression after cerebral ischemia and inhibits progressive neuronal death in mouse brain cells and slices

Brain Pathology, Volume 33, Issue 1, January 2023., 2023
There is no pharmacological treatment available to limit progressing neuronal death after cerebral ischemia. Here we show that targeting the interaction of GABAB receptors with CaMKII using a synthetic interfering peptide after an excitotoxic insult in cultured neurons or in brain slices from MCAO‐treated mice restored downregulated GABAB receptor ...

Electrophysiological evaluation of chronic neuropathic pain of spinal cord injury origin [PDF]

The Indian Journal of Neurotrauma, 2010
The chronic neuropathic pain of spinal cord injury origin has been shown to be related to permanent neurochemical changes in the dorsal horn neurons thus producing spontaneous discharges of central nociceptive neurons resulting in chronic pain.

A 20-Channel Magnetoencephalography System Based on Optically Pumped Magnetometers [PDF]

, 2017
We describe a multichannel magnetoencephalography (MEG) system that uses optically pumped magnetometers (OPMs) to sense the magnetic fields of the human brain. The system consists of an array of 20 OPM channels conforming to the human subject's head, a person-sized magnetic shield containing the array and the human subject, a laser system to drive the ...

Bayesian Multi--Dipole Modeling of a Single Topography in MEG by Adaptive Sequential Monte Carlo Samplers [PDF]

Inverse Problems 30 (2014) 045010, 2013
In the present paper, we develop a novel Bayesian approach to the problem of estimating neural currents in the brain from a fixed distribution of magnetic field (called \emph{topography}), measured by magnetoencephalography. Differently from recent studies that describe inversion techniques, such as spatio-temporal regularization/filtering, in which ...

Cortical Excitability Before and After Long‐Term Perampanel Treatment for Epilepsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Antiseizure medications (ASMs), which may influence cortical excitability, are the mainstay of epilepsy treatment. Transcranial magnetic stimulation (TMS) helps evaluate cortical excitability. We assessed changes in TMS responses using serial TMS measurements in people treated with an adjunctive noncompetitive AMPA‐receptor ...

Airborne Ultrasonic Tactile Display BCI [PDF]

Brain-Computer Interface Research - A State-of-the-Art Summary 4. SpringerBriefs in Electrical and Computer Engineering. 2015. p. 57-65, 2015
This chapter presents results of our project, which studied whether contactless and airborne ultrasonic tactile display (AUTD) stimuli delivered to a user's palms could serve as a platform for a brain computer interface (BCI) paradigm. We used six palm positions to evoke combined somatosensory brain responses to implement a novel contactless tactile ...

Transcranial Direct Current Stimulation Improves Some Neurophysiological Parameters but not Clinical Outcomes after Severe Traumatic Brain Injury

Journal of Integrative Neuroscience, 2023
Background: Disorders of consciousness (DOC) are one of the clinical hallmarks of severe traumatic brain injury (TBI). DOC impair patient life quality and increase the burden on their families and society.

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

Advanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.

Anticipation across modalities in children and adults: Relating anticipatory alpha rhythm lateralization, reaction time, and executive function

Developmental Science, Volume 26, Issue 1, January 2023., 2023
Participants analyzed included 40 adults aged 18–20 and 40 children aged 6–8, who were cued with a sound that directed their attention to the location of an upcoming stimulus. The stimulus presented to the right or left of the participant in either the tactile, auditory or visual modalities and participants responded to the stimulus by pressing a foot ...
