The emotional gatekeeper: a computational model of attentional selection and suppression through the pathway from the amygdala to the inhibitory thalamic reticular nucleus [PDF]

open access: yes, 2016
In a complex environment that contains both opportunities and threats, it is important for an organism to flexibly direct attention based on current events and prior plans. The amygdala, the hub of the brain's emotional system, is involved in forming and

Thalamic inflammation after brain trauma is associated with thalamo-cortical white matter damage [PDF]

open access: yes, 2015
Background Traumatic brain injury can trigger chronic neuroinflammation, which may predispose to neurodegeneration. Animal models and human pathological studies demonstrate persistent inflammation in the thalamus associated with axonal injury, but this ...

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]

open access: yes, 2001
The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

Neural correlates of phonological, orthographic and semantic reading processing in dyslexia [PDF]

open access: yes, 2018
Developmental dyslexia is one of the most prevalent learning disabilities, thought to be associated with dysfunction in the neural systems underlying typical reading acquisition. Neuroimaging research has shown that readers with dyslexia exhibit regional

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 ...

Confluent Thalamic Hyperintensities in CADASIL [PDF]

open access: yes, 2010
Background: CADASIL is responsible for diffuse hyperintensities in the white matter on FLAIR images. These lesions are often associated with focal lesions in the basal ganglia such as lacunar infarctions.

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.
