Birth time can alter when widespread neuron death begins

Moving birth a day early triggers an early start to widespread neuron death, according to new research.

Aerobic exercise training linked to enhanced brain function

Individuals at risk for Alzheimer’s disease (AD) because of family history or genetic predisposition who engaged in six months of aerobic exercise training improved their brain glucose metabolism and higher-order thinking abilities (e.g., planning and …

Effect of coagulation factor fibrinogen on damaged brain

Researchers have discovered the influence of the coagulation factor fibrinogen on the damaged brain.

Brain drowns in its own fluid after a stroke

Cerebral edema, swelling that occurs in the brain, is a severe and potentially fatal complication of stroke. New research shows for the first time that the glymphatic system – normally associated with the beneficial task of waste removal — goes awry d…

Students’ feelings about high school are mostly negative

In a nationwide US survey of 21,678 US high school students, researchers found that nearly 75% of the students’ self-reported feelings related to school were negative.

Brain’s ‘GPS system’ toggles between present and possible future paths in real time

In a study of rats navigating a simple maze, neuroscientists have discovered how the brain may generate such imagined future scenarios. The work provides a new grounding for understanding not only how the brain makes decisions but also how imagination …

Patterns in the brain shed new light on how we function

Patterns of brain connectivity take us a step closer to understanding the key principles of cognition.

High and low exercise intensity found to influence brain function differently

A new study shows for the first time that low and high exercise intensities differentially influence brain function. Using resting state functional magnetic resonance imaging (Rs-fMRI), a noninvasive technique that allows for studies on brain connectiv…

How the human brain solves complex decision-making problems

A new study on meta reinforcement learning algorithms helps us understand how the human brain learns to adapt to complexity and uncertainty when learning and making decisions. A research team succeeded in discovering both a computational and neural mec…

Researchers discover how cellular senescence leads to neurodegeneration

Although a link has been established between chronic inflammation and neurodegenerative diseases, there have been many open questions regarding how cellular senescence, a process whereby cells that stop dividing under stress spew out a mix of inflammat…
