Stress alters brain function by modifying the structure and function of neurons and astrocytes. The fine processes of astrocytes are critical for the clearance of neurotransmitters during synaptic transmission. Thus, experience-dependent remodeling of glial processes is anticipated to alter the output of neural circuits.. ..Significance statement Astrocytes play important roles in synaptic transmission by extending… Continue reading Emotional #stress induces structural #plasticity in Bergmann glial cells via an AC5-CPEB3-GluA1 pathway

Central sensory-motor crosstalk in the neural gut-brain axis
The neural gut-brain axis consists of viscerosensory and autonomic motor neurons innervating the gastrointestinal (GI) tract. Sensory neurons transmit nutrient-related and non-nutrient-related information to the brain, while motor neurons regulate GI motility and secretion. Previous research provides an incomplete picture of the brain nuclei that are directly connected with the neural gut-brain axis, and no… Continue reading Central sensory-motor crosstalk in the neural gut-brain axis
BrainAGE and regional volumetric analysis of a Buddhist monk: a longitudinal MRI case study
Yongey Mingyur Rinpoche (YMR) is a Tibetan Buddhist monk, and renowned meditation practitioner and teacher who has spent an extraordinary number of hours of his life meditating. The brain-aging profile of this expert meditator in comparison to a control population was examined using a machine learning framework, which estimates “brain-age” from brain imaging. YMR’s brain-aging… Continue reading BrainAGE and regional volumetric analysis of a Buddhist monk: a longitudinal MRI case study
#Diet modulates brain network stability, a biomarker for brain #aging, in young adults
..One cohort was scanned under standard diet, overnight fasting, and ketogenic diet conditions. To isolate the impact of fuel type, an independent overnight fasted cohort was scanned before and after administration of a calorie-matched glucose and exogenous ketone ester (D-β-hydroxybutyrate) bolus. Across the life span, brain network destabilization correlated with decreased brain activity and cognitive… Continue reading #Diet modulates brain network stability, a biomarker for brain #aging, in young adults
Boom Chack Boom—A multimethod investigation of motor inhibition in professional #drummers
Our hands are the primary means for motor interaction with the environment, and their neural organization is fundamentally asymmetric: While most individuals can perform easy motor tasks with two hands equally well, only very few individuals can perform complex fine motor tasks with both hands at a similar level of performance.. ..Our results show that… Continue reading Boom Chack Boom—A multimethod investigation of motor inhibition in professional #drummers
Effects of #tranexamic acid on death, disability, vascular occlusive events and other morbidities in patients with acute traumatic #brain injury (CRASH-3): a randomised, placebo-controlled trial
Tranexamic acid reduces surgical bleeding and decreases mortality in patients with traumatic extracranial bleeding. Intracranial bleeding is common after traumatic brain injury (TBI) and can cause brain herniation and death. We aimed to assess the effects of tranexamic acid in patients with TBI. The risk of head injury-related death reduced with tranexamic acid in patients… Continue reading Effects of #tranexamic acid on death, disability, vascular occlusive events and other morbidities in patients with acute traumatic #brain injury (CRASH-3): a randomised, placebo-controlled trial
