Cerebral Oxygenation and Activity During Surgical Repair of Neonates With Congenital Diaphragmatic Hernia: A Center Comparison Analysis

open access: yesFrontiers in Pediatrics, 2021
Background and aim: Neonatal brain monitoring is increasingly used due to reports of brain injury perioperatively. Little is known about the effect of sedatives (midazolam) and anesthetics (sevoflurane) on cerebral oxygenation (rScO2) and cerebral ...

Pre-stroke Physical Activity and Cerebral Collateral Circulation in Ischemic Stroke: A Potential Therapeutic Relationship?

open access: yesFrontiers in Neurology, 2022
Favorable cerebral collateral circulation contributes to hindering penumbral tissue from progressing to infarction and is associated with positive clinical outcomes after stroke. Given its clinical importance, improving cerebral collateral circulation is

Longitudinal Impact of Physical Activity on Brain Pulsatility Index and Cognition in Older Adults with Cardiovascular Risk Factors: A NIRS Study

open access: yesBrain Sciences, 2021
Recent studies have shown that optical indices of cerebral pulsatility, including cerebral pulse amplitude, are linked to cerebrovascular health. A chronically higher cerebral pulsatility is associated with cognitive decline.

Attenuated activation of the anterior rostral medial prefrontal cortex on self-relevant social reward processing in individuals with autism spectrum disorder

open access: yesNeuroImage: Clinical, 2020
The social motivation hypothesis posits that people with autism spectrum disorder (ASD) find social stimuli less rewarding and are therefore less motivated towards social interaction than people with neuro-typical development (TD).

Dopaminergic modulation of regional cerebral blood flow: An arterial spin labelling study of genetic and pharmacological manipulation of COMT activity

open access: yesNeuroImage, 2021
Dopamine has direct and complex vasoactive effects on cerebral circulation. Catechol-O-methyltransferase (COMT) regulates cortical dopamine, and its activity can be influenced both genetically and pharmacologically.

Mechanisms of exercise-induced muscle damage and fatigue: Intracellular calcium accumulation

open access: yesJournal of Physical Fitness and Sports Medicine, 2012
Contraction-induced compromise of muscle function and, in the extreme, muscle damage has been linked to loss of Ca2+ homeostasis and resultant sustained elevation of intracellular Ca2+ ([Ca2+]i).

Sympathetic Activity in Cerebral Embolism

open access: yesJapanese Heart Journal, 1969
Responses of the right cervical sympathetic nerve and the systemic arterial pressure to vertebral and carotid embolism were examined in rabbits anesthetized with α-chloralose and the following results were obtained: (1) Vertebral embolism resulted in a marked rise of blood pressure, while carotid embolism resulted a fall.(2) Hypertension produced by ...

ELECTROENCEPHALOGRAPHIC ASSESSMENT OF CEREBRAL ACTIVITY IN PATIENTS WITH SPINAL MUSCULAR ATROPHY

open access: yesThe Iraqi Journal of Medical Sciences, 2016
Background:Spinal muscular atrophies are a group of degenerative diseases primarily affecting the anterior horn cells of the spinal cord and motor cells of cranial nerve nuclei.

Correlation and Similarity between Cerebral and Non-Cerebral Electrical Activity for User’s States Assessment

open access: yesSensors, 2019
Human tissues own conductive properties, and the electrical activity produced by human organs can propagate throughout the body due to neuro transmitters and electrolytes.

Electrophysiological Effects of Transcranial Direct Current Stimulation on Neural Activity in the Rat Motor Cortex

open access: yesFrontiers in Neuroscience, 2020
Transcranial direct current stimulation (tDCS) is a non-invasive technique that modulates the neuronal membrane potential. We have previously documented a sustainable increase in extracellular dopamine levels in the rat striatum of cathodal tDCS ...
