Got fatigue? Study further pinpoints brain regions that may control it

Scientists using MRI scans and computer modeling say they have further pinpointed areas of the human brain that regulate efforts to deal with fatigue. The findings, they say, could advance the development of behavioral and other strategies that increase physical performance in healthy people, and also illuminate the neural mechanisms that contribute to fatigue in people with depression, multiple sclerosis […]

Hunger encourages risk-taking

The lives of animals in the wild are full of risky situations with uncertain outcomes. Whether they are exploring new habitats in unfamiliar terrain or searching for new food sources, they run the risk of being caught and killed by a predator. In many instances, their very survival depends on a single decision. Whether an animal decides to take a […]

Scientists reveal how the brain may fuel intense neural communication

Results suggest retrieval of cellular powerplants via an energy feedback loop sustains communication Our thoughts, feelings, and movements are controlled by billions of neurons talking to each other at trillions of specialized communication points called synapses. In an in-depth study of neurons grown in laboratory petri dishes, researchers discovered how the chattiest of some synapses find the energy to support […]
