The research opens possibilities for targeting the brain-to-gut signaling pathway for new therapies. Chronic stress can inflame the gut — now scientists know why

Frenemies Take a Toll

According to psychologists, ambivalent relationships, known as frenemies, which combine positive and negative aspects, can be more detrimental to health than purely negative relationships. Research reveals that interacting with individuals who evoke mixed feelings can raise blood pressure and lead to negative physical symptoms. Even a single ambivalent interaction can have adverse effects on well-being. Unpredictability increases pain from unpleasant interactions, and rumination contributes to the negative impact of such relationships. Recognizing the harmful effects of frenemies is important for maintaining overall health and well-being. Opinion | Ambivalent Relationships May Be Hazardous to Your Health. (gift article)

The Neuroscience of Hangry

Neuroscientists have discovered a cluster of cells called AgRP neurons that stimulate appetite and play a vital role in the infamous "hangry" feeling. These cells near the brain's blood supply receive signals from the stomach and fat tissue, influencing our hunger levels. By manipulating AgRP neuron activity in mice, researchers have identified how they trigger food-seeking behavior and respond to the presence of nutrients. This breakthrough could lead to new therapies for eating disorders like anorexia and overeating. By understanding and controlling the hangry feeling, scientists hope to revolutionize our ability to manage our diets effectively. Neuroscientists May Have Found the Part of Your Brain That Makes You Hangry

Electrical Activity Surges in the Dying Brain

A new study reveals that dying brains experience a surge of electrical activity, challenging the assumption that brain activity decreases during dying. Researchers monitored four comatose patients who died in a neurointensive care unit and observed a surge of neurophysiological activity in regions associated with conscious processing. This surge included increased synchronization and connectivity between different brain regions. While the study doesn't directly explain near-death experiences, it suggests that the observed brain activity pattern may contribute to the vivid perceptions reported during such experiences, prompting further investigation into the nature of human consciousness. Scientists monitored four dying patients' brains. Here's what they saw . In the late 2000s, David Auyong and I observed the same phenomenon while on call: Processed electroencephalogram during donation after cardiac death.
