Healthy study volunteers whose red blood cells contained higher concentrations of omega-3 fatty acids were found to have better brain structure and cognitive function in middle age.

Researchers have pioneered the CMU Array — a customizable, 3D nano-printed, ultra-high-density microelectrode array platform for next generation brain-computer interfaces. This technology can transform the way doctors are able to treat neurological di…

Researchers report that viewing, feeling, and touching real dogs leads to increasingly higher levels of activity in the prefrontal cortex of the brain. The study shows that this effect persists after the dogs are no longer present, but is reduced when …

In the brain of adult mammals neural stem cells ensure that new nerve cells, i.e. neurons, are constantly formed. This process, known as adult neurogenesis, helps mice maintain their sense of smell. A research team recently discovered a second stem cel…

Researchers have shown that when brain cells are directly exposed to blood taken from COVID-19 patients with delirium, there is an increase in cell death and a decrease in the generation of new brain cells. Delirium represents a state of confusion indi…

Evidence in mice and human brain tissue reveals a mechanism that may explain the sex-based differences in Alzheimer’s disease, including why females are more vulnerable. Researchers report that female brains show higher expression of an X-linked enzym…

Newly discovered biological changes in mothers who suffer postpartum depression may help explain the condition, yield long-sought treatments and let doctors identify those at risk even before their babies are born.

A large study has looked at DNA methylation in Alzheimer’s disease. DNA methylation is the process by which the activity of genes is regulated, acting a bit like a dimmer-switch to turn genes on or off. Increasingly, this process is thought to have a k…

You may not realize it, but each time you recall a memory — like your first time riding a bike or walking into your high school prom — your brain changes the memory ever so slightly. It’s almost like adding a filter, with details being filled in and …

Researchers demonstrate the relationship between the rate of cognitive fatigue in MS and microstructural brain changes. The findings promise to advance development of clinical interventions for disabling fatigue.
