Brain-circuit discovery may help explain sex differences in binge drinking

A brain circuit that works as a ‘brake’ on binge alcohol drinking may help explain male-female differences invulnerability to alcohol use disorders, according to a preclinical study.

Treating severe depression with on-demand brain stimulation

Physicians have successfully treated a patient with severe depression by tapping into the specific brain circuit involved in depressive brain patterns and resetting them using the equivalent of a pacemaker for the brain.

Directly into the brain: A 3D multifunctional and flexible neural interface

Although measuring the electrical activity of neurons is useful in many disciplines, making durable neural interfacing brain chip implants with negligible adverse effects has proven challenging. Now, scientists have developed a flexible multifunctional…

Gene therapy can restore vision after stroke

Vision loss can be a side effect from stroke. Neurons don’t regenerate, and stem cell therapy is costly, difficult, and chancy. Researchers have figured out a way to use gene therapy to recover lost vision after a stroke in a mouse model.

‘Fight or flight’ – unless internal clocks are disrupted, study in mice shows

Daily release of hormones depends on the coordinated activity of clocks in two parts of the brain, a finding that could have implications for human diseases.

Early accumulation of tau in the brain predicts memory decline in Alzheimer’s disease

Researchers have compared how well different Alzheimer’s biomarkers predict the progression of the disease and its effect on the memory. They found that early accumulation of tau proteins in the brain as measured by PET scanner was more effective at pr…

Stress of COVID-19 pandemic caused irregular menstrual cycles, study found

Women and people who menstruate experienced irregularities in their menstrual cycle because of increased stress during the COVID-19 pandemic, a new study has found.

Back pain: Psychological treatment shown to yield strong, lasting pain relief, alter brain networks

A study of chronic back pain patients finds that more than two-thirds of those who underwent a novel, 4-week psychological treatment were pain-free or nearly pain-free afterward. Those in the treatment group also saw brain regions involved in pain proc…

Hippocampus is the brain’s storyteller

A new brain imaging study shows that the hippocampus is the brain’s storyteller, connecting separate, distant events into a single narrative.

How our unique brain takes shape during mid-pregnancy

Researchers have identified key changes in gene expression and structure in the developing human brain that makes it unique among all animal species.
