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

Regulatory 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

Pediatric 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 ...

The general anaesthetic etomidate inhibits the excitability of mouse thalamocortical relay neurons by modulating multiple modes of GABA_A receptor-mediated inhibition [PDF]

, 2014
Modulation of thalamocortical (TC) relay neuron function has been implicated in the sedative and hypnotic effects of general anaesthetics. Inhibition of TC neurons is mediated predominantly by a combination of phasic and tonic inhibition, together with a

Early ictal recruitment of midline thalamus in mesial temporal lobe epilepsy

Annals 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

Frontiers 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

Cell 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

Frontiers 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

Cell 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.

Causal hierarchy within the thalamo-cortical network in spike and wave discharges [PDF]

, 2009
Background: Generalised spike wave (GSW) discharges are the electroencephalographic (EEG) hallmark of absence seizures, clinically characterised by a transitory interruption of ongoing activities and impaired consciousness, occurring during states of ...
