News-Medical: Researchers discover how behavior is organized in the brain

Driving to work, typing an email or playing a round of golf–people perform actions such as these throughout the day. But neuroscientists are still unsure how the brain orchestrates complex actions or switches to a new action–behaviors that are impaired in disorders such as Parkinson’s disease or obsessive-compulsive disorder (OCD).

Scientific American: “Traveling” brain waves may be critical for cognition

The electrical oscillations we call brain waves have intrigued scientists and the public for more than a century. But their function—and even whether they have one, rather than just reflecting brain activity like an engine’s hum—is still debated. Many neuroscientists have assumed that if brain waves do anything, it is by oscillating in synchrony in […]

Science Alert: Watch what happens to your brain when the heart pumps blood

Your heart doesn’t exist in isolation, fiercely pumping blood while the rest of your viscera remain perfectly still. Each beat sends tiny shudders as blood moves around – and now a new MRI technique has managed to capture that effect on the brain in real-time, amplifying it to observe how it works.

U.S. News & World Report: Fit at midlife may mean healthier brain, stronger heart later

If you’re fit in middle age, you might be guarding against not only depression as a senior, but also dying from heart disease if you do develop depression, a new study suggests. Among nearly 18,000 Medicare patients, the most fit were 16 percent less likely to develop depression, the researchers found. (June 27, 2018) Read […]

Medical Xpress: Defining the brain mosaic in fruit flies and humans

Similar to a mosaic floor where different patterned tiles come together to make a composite and holistic image, our brains consist of billions of unique neurons that connect and generate coordinated brain activity. Unlike a static mosaic, however, our brains are dynamic and activity in the brain changes based on environmental cues. So what makes […]

News-Medical: Study details role of dopamine in unlearning fear

Researchers at the RIKEN Center for Brain Science have discovered a circuit in the brain that is necessary for unlearning fear. Published in Nature Communications, the study details the role of dopamine in ensuring that rats stop being afraid when there isn’t anything to be afraid of anymore. Like animals, people develop conditioned responses, especially […]

Medical Xpress: How your brain decides between knowledge and ignorance

We have a ‘thirst for knowledge’ but sometime ‘ignorance is bliss’, so how do we choose between these two mind states at any given time? UCL psychologists have discovered our brains use the same algorithm and neural architecture to evaluate the opportunity to gain information, as it does to evaluate rewards like food or money. […]

Live Science: Is ‘pregnancy brain’ real?

If you’ve ever found yourself at a real loss for words while pregnant, or you feel like you just keep forgetting to book appointments during those nine months of expecting, you’re not the only one. Surveys have found that about 64 percent of expecting mothers report struggling more to find the right words or focus […]

Medical News Today: Brain study reveals why some people fail to stick to their diet

Differences in brain anatomy might explain why some individuals struggle to maintain a healthful diet while others do not. This was the conclusion that researchers came to after finding that gray matter volume in two brains regions predicted ability to exercise control over food choices.
