Study examines how social rank affects response to stress

Scientists say their study could shed light on stress-related mental illnesses but that more research is needed.

Microrobot technology: Externally connecting in vivo neural networks

Researchers have developed a technology for delivering a microrobot to a target point of a hippocampus in an in-vitro environment, connecting neural networks, and measuring neural signals. The findings are expected to contribute to neural network resea…

Fluid flow in the brain can be manipulated by sensory stimulation

Researchers report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. The study demonstrates that manipulating blood flow in the brain with visual stimulation induces complementary fluid flow. The findings could impac…

Newly discovered trigger for major depression opens new possibilities for treatments

The simple amino acid glycine looks to be a previously unknown contributor to depression.

Imaging brain connections can predict improvements in obsessive-compulsive disorder patients after deep brain stimulation

Deep brain stimulation (DBS) is a promising therapy for treatment-resistant obsessive-compulsive disorder (OCD). A new study has found that mapping neural connections in the brains of OCD patients offers key insights that explain the observed improveme…

Phthalate alternative may harm brain development and health

Growing concerns over the potential health effects of exposure to phthalates have led to a search for safer alternatives. Researchers found that the chemical acetyl tributyl citrate (ATBC) might not be the best replacement.

Blind people sense their heartbeats better than sighted

Blind people are better at sensing their own heartbeats than sighted, shows a new study. The study indicates that blindness leads to a heightened ability in feeling signals from the inner body.

Dieting: Brain amplifies signal of hunger synapses

Many people who have dieted are familiar with the yo-yo effect: after the diet, the kilos are quickly put back on. Researchers have now shown in mice that communication in the brain changes during a diet: The nerve cells that mediate the feeling of hun…

Where does your brain want to have lunch?

New research advances scientific understanding of how the brain weighs decisions involving what people like or value, such as choosing which book to read, which restaurant to pick for lunch — or even, which slot machine to play in a casino.

A higher dose of magnesium each day keeps dementia at bay

More magnesium in our daily diet leads to better brain health as we age, according to scientists.
