Researchers uncover large-scale brain patterns and networks which control sleep

An international study headed by researchers from Aarhus University has for the first time uncovered the large-scale brain patterns and networks in the brain which control sleep, providing knowledge which in the future may in the long term help the many Danes large proportion of people who experience problems sleeping.

Novel MRI sensor can peer deep into the brain to detect intracellular calcium activity

Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain.

Researchers map an awake-brain

There are ethical dilemmas in cases where a person is unresponsive after a major trauma but is awake within (unresponsive wakefulness syndrome) and when a person is brain dead or truly unconscious. In these cases stopping life support can be a tough decision.

Neurobiologists uncover key component of how the human brain marks time

With a little help from HBO's "Curb Your Enthusiasm," University of California, Irvine neurobiologists have uncovered a key component of how the human brain marks time.

New findings provide clues about neural circuitries that facilitate or undermine adaptation

Neighborhood violence has been associated with adverse health effects on youth, including sleep loss, asthma and metabolic syndrome. Yet some youth living in high-crime neighborhoods manage to avoid these effects.

MGH researchers use advanced imaging technology to measure magnetite levels in the brain

Investigators at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital have used magnetoencephalography - a technology that measures brain activity by detecting the weak magnetic fields produced by the brain's normal electrical currents - to measure levels of the iron-based mineral called magnetite in the human brain.

Research highlights physical changes in the brain of self-injuring teen girls

The brains of teenage girls who engage in serious forms of self-harm, including cutting, show features similar to those seen in adults with borderline personality disorder, a severe and hard-to-treat mental illness, a new study has found.

Researchers find unique patterns of neural communication in the brains of children with autism

Think of the brain as a complex transportation hub, a place where neural traffic heads off in any number of directions to make connections while processing something as simple as a mother's smile.

Weight loss success associated with brain areas involved in self-control

New research suggests that higher-level brain functions have a major role in losing weight. In a study among 24 participants at a weight-loss clinic, those who achieved greatest success in terms of weight loss demonstrated more activity in the brain regions of the lateral prefrontal cortex associated with self-control.
