Medical Xpress: How the brain makes rapid, fine adjustments in motor activity

Northwestern Medicine scientists have discovered a neural mechanism for making rapid, fine adjustments in precise motor activity. The study, led by Lee Miller, professor of physiology at Northwestern University Feinberg School of Medicine, found that the brain’s premotor cortex may use a “neural scratch pad” between it and the primary motor cortex to calculate fine […]

MIT News: Electrical properties of dendrites help explain our brain’s unique computing power

Neurons in the human brain receive electrical signals from thousands of other cells, and long neural extensions called dendrites play a critical role in incorporating all of that information so the cells can respond appropriately. Using hard-to-obtain samples of human brain tissue, MIT neuroscientists have now discovered that human dendrites have different electrical properties from […]

Science Daily: Are trigger warnings emotionally protective?

Do you like to see warnings about violent or other distressing content before watching a TV show or movie, or reading a book? New University of Michigan research finds that some people feel less negative about the content when they receive trigger warnings, but those who believe them to be protective do not feel better […]

PsyPost: Neuroimaging study: Facebook use linked to enlarged brain structures

Spending time on Facebook is associated with increased grey matter volume in brain structures linked to the processing social information, according to new neuroimaging research published in the journal Social Neuroscience. “I have been working on the ‘dark side’ of excessive use of technologies for almost a decade,” said Ofir Turel of the University of […]

Science Daily: How the human brain detects, identifies, and acts on taste

Sweet and bitter flavors are identified as soon as they are tasted, according to human neural and behavioral data published in eNeuro. The study provides new insight into how the brain rapidly detects and discriminates between potentially nutritious and toxic substances.The sense of taste, similar to that of smell, guides an organism toward stimuli that […]

Medical News Today: Is sleeping too much bad for your brain?

The largest sleep study ever concludes that sleeping too little or too much has a negative impact on our cognitive ability, but not on our short-term memory. As years of research mount up, we are steadily improving our understanding of sleep.However, despite making up around one third of our entire lives, sleep still holds many […]

The Wall Street Journal: How to disconnect from ‘always on’ work culture

I have a masochistic need to please bosses, so I’m never more than a few feet from my iPhone (notifications humming at all hours) and I never leave home without a MacBook in tow. Just in case. My manager, who once mentioned pointedly that he has a “perverse respect for workaholics,” recently emailed me a […]
