Overweight/obese people with diabetes at increased risk of brain abnormalities

Overweight and obese individuals with early stage type 2 diabetes (T2D) had more severe and progressive abnormalities in brain structure and cognition compared to normal-weight study participants, research indicates.

Neurons’ faulty wiring leads to serotonin imbalance, depression-like behavior in mice

A gene has been identified that allows neurons that release serotonin to evenly spread their branches throughout the brain. Without this gene, these branches become entangled, leading to haphazard serotonin distribution, and signs of depression in mice…

Nose2Brain: Better therapy for multiple sclerosis

Medically active substances are normally distributed via the blood — either directly by injection into the bloodstream or indirectly, for example through the digestive tract after oral administration. In many diseases, however, it is of decisive impor…

When students pay attention in class, their brains are in sync

When people in a group are engaged with each other and with the world around them, their brainwaves show similar patterns. That’s the conclusion of researchers who used portable EEG to simultaneously record brain activity from a class of high school st…

Antidepressant may enhance drug delivery to the brain

Pairing the antidepressant amitriptyline with drugs designed to treat central nervous system diseases, enhances drug delivery to the brain by inhibiting the blood-brain barrier in rats, new research shows. The blood-brain barrier serves as a natural, p…

New analysis of brain network activity offers unique insight into epileptic seizures

Little is known about which specific areas of the brain contribute to a patient’s epileptic network or the roles these different areas play. As a group of researchers now reports one way to get closer to the complex wiring of the human brain is by merg…

Working human forebrain circuits assembled in a lab dish

Peering into laboratory glassware, researchers have watched stem-cell-derived nerve cells arising in a specific region of the human brain migrate into another brain region. This process recapitulates what’s been believed to occur in a developing fetus,…

Cannabis use in adolescence linked to schizophrenia

A new study points to cannabis as a trigger for schizophrenia. The research finds that smoking pot or using cannabis in other ways during adolescence may serve as a catalyst for schizophrenia in individuals already susceptible to the disorder.

In a neuro-techno future, human rights laws will need to be revisited

New human rights laws to prepare for advances in neurotechnology may put the ‘freedom of the mind’ at risk.

Immune system, brain structure and memory linked

Scientists have demonstrated that both the structure of the brain and several memory functions are linked to immune system genes.
