Short-term effect of adrenalin on S-100b and N-CAM level in the different rat brain areas

open access: yesRegulatory Mechanisms in Biosystems, 2015
The level of adrenalin grows under stress conditions, sense of danger, anxiety, fear, trauma, burns and shock. In high concentrations adrenaline increases the speed of protein catabolism.

MRI Analysis of Neurofibromatosis Type 1

open access: yesPediatric Neurology Briefs, 1998
Serial MRI scans of 30 patients (mean age, 12 years) with neurofibromatosis Type 1 (NF-1) showed the evolution of high-signal brain lesions in a prospective study at the University of Connecticut Health Center, Farmington, and Children’s Medical Center ...

MRI in Athetotic Cerebral Palsy

open access: yesPediatric Neurology Briefs, 1992
The MRI in 22 children with athetotic cerebral palsy was studied in the Department of Pediatric Neurology, Seirei-Mikatabara General Hospital, Hamamatsu, the Department of Pediatrics, National Rehabilitation Center for Disabled Children, Tokyo, and the ...

Early ictal recruitment of midline thalamus in mesial temporal lobe epilepsy

open access: yesAnnals of Clinical and Translational Neurology, 2019
The causal role of midline thalamus in the initiation and early organization of mesial temporal lobe seizures is studied. Three patients undergoing stereoelectroencephalography were enrolled for the placement of an additional depth electrode targeting ...

Interactions Between Motor Thalamic Field Potentials and Single-Unit Spiking Are Correlated With Behavior in Rats

open access: yesFrontiers in Neural Circuits, 2020
Field potential (FP) oscillations are believed to coordinate brain activity over large spatiotemporal scales, with specific features (e.g., phase and power) in discrete frequency bands correlated with motor output.

Divergent outputs of the ventral lateral geniculate nucleus mediate visually evoked defensive behaviors

open access: yesCell Reports, 2021
Summary: Rapid alternations between exploration and defensive reactions require ongoing risk assessment. How visual cues and internal states flexibly modulate the selection of behaviors remains incompletely understood.

Attenuation of Native Hyperpolarization-Activated, Cyclic Nucleotide-Gated Channel Function by the Volatile Anesthetic Sevoflurane in Mouse Thalamocortical Relay Neurons

open access: yesFrontiers in Cellular Neuroscience, 2021
As thalamocortical relay neurons are ascribed a crucial role in signal propagation and information processing, they have attracted considerable attention as potential targets for anesthetic modulation.

A cortico-subcortical loop for motor control via the pontine reticular formation

open access: yesCell Reports
Summary: Movement and locomotion are controlled by large neuronal circuits like the cortex-basal ganglia (BG)-thalamus loop. Besides the inhibitory thalamic output, the BG directly control movement via specialized connections with the brainstem.

A novel image segmentation method based on spatial autocorrelation identifies A-type potassium channel clusters in the thalamus

open access: yeseLife
Unsupervised segmentation in biological and non-biological images is only partially resolved. Segmentation either requires arbitrary thresholds or large teaching datasets.

Pain Relief in a Trigeminal Neuralgia Model via Optogenetic Inhibition on Trigeminal Ganglion Itself With Flexible Optic Fiber Cannula

open access: yesFrontiers in Cellular Neuroscience, 2022
The trigeminal ganglion (TG) is the primary site of aberration in trigeminal neuralgia (TN), and hence a crucial site where afferent input can be modulated.
