Stress rewires brain control networks, boosting pain tolerance in ice test

Stress resilience isn’t a flatline. It’s a flex, according to new research from Florida International University. Marcelo Bigliassi, assistant professor of psychophysiology, and Ph.D. student Dayanne Antonio thrive in creating stressful environments.

They set out to explore how the brain’s internal wiring and a person’s subjective experience of stress interact to determine how they respond to stressful situations. The findings were published in the Journal of Applied Physiology.

Study participants plunged one hand into a bucket of ice-cold water. Frigidly cold water. As the seconds ticked by, the body’s stress systems revved up, and their skin began to sweat.

Enhancer dynamics and cellular architecture in the human spinal cord

Human spinal cord enhancer dynamics and cellular architecture.

The researchers present an innovative framework redefining human spinal cord cellular diversity through epigenetic configuration and spatial organization.

They identify unseen enhancer classes that define both stable cell-type identity and transitions between cells undergoing differentiation.

The authors also identify gene regulatory networks in glial cells that reorganize along the rostrocaudal axis, demonstrating anatomical differences in gene regulation.

The researchers demonstrate spatial organization of cells into distinct cellular networks and address the functional significance of this observation in the context of paracrine signaling. sciencenewshighlights ScienceMission https://sciencemission.com/Enhancer-dynamics

Kandror et al. present an innovative framework redefining human spinal cord cellular diversity through epigenetic configuration and spatial organization. They identify unseen enhancer classes, show cell-type-specific reconfiguration of gene regulatory networks along the rostrocaudal axis, and uncover cellular networks mediated by discrete paracrine signaling, challenging conventional definitions of cellular state.

Inflammation, Limbic White Matter Microstructure, and Clinical Symptoms in Retired American Football Players With Repetitive Head Impacts

Background and ObjectivesThe link between repetitive head impact (RHI) exposure, later-life cognitive decline, and neurobehavioral dysregulation (NBD) is not well understood. Recent work has implicated inflammation and limbic dysfunction as relevant RHI…

12 (Every) Plague That Wiped Out Humanity in Sci-Fi Movies — Explored

Humans think they can conquer everything in this world, like they have a solution for every problem, but this is where people get greedy, overambitious and most importantly, desperate. For example, in most of the science fiction and survival thrillers, people dig their own grave by creating deadly viruses in the labs, sometimes for political reasons and sometimes to create a medical miracle. These movies show how these man-made viruses wipe out humanity and make the world a living hell for a few immune survivors. Now, this has been a widely explored trope in every survival thriller, but deep beneath this layer, these films talk about something really ominous about our future.
