The area of the brain that produces dopamine, and the brain’s separate biological clock that regulates daily physiological rhythms, are linked, suggests a new study[1]. High-calorie foods disrupt normal feeding schedules, resulting in overconsumption, the work also found. “The diet in the U.S. and other nations has changed dramatically in the last 50 years or… Read more

Cardiorespiratory exercise – walking briskly, running, biking and just about any other exercise that gets your heart pumping – is good for your body, but can it also slow cognitive changes in your brain? New evidence of an association between cardiorespiratory fitness and brain health, particularly in gray matter and total brain volume is shown… Read more

A laser-assisted imaging tool was used by Johns Hopkins Medicine researchers to observe what happens in brain cells of mice learning to reach out and grab a pellet of food. Their experiments, they say, add to evidence that such motor-based learning can occur in multiple areas of the brain, even ones not typically associated with… Read more

Brain mechanisms and functional regions that underlie confirmation bias – a phenomenon where people strongly favor information that reinforces their existing opinions over contradictory ones – have been identified by an international research team of neuroscientists. The findings[1] provide insight into a fundamental property of belief formation that has been documented by psychologists and economists… Read more

Electroencephalograms may not always be a reliable reflection of consciousness, according to new research in rats[1]. Scientists are still debating just how to reliably determine whether someone is conscious. This question is of great practical importance when making medical decisions about anesthesia or treating patients in a vegetative state or coma. “EEG doesn’t necessarily correlate… Read more
