Live imaging method brings structural information to mapping of brain function

Neuroscientists distinguish brain regions based on what they do, but now have a new way to overlay information about how they are built, too.

The key to happiness: Friends or family?

Think spending time with your kids and spouse is the key to your happiness? You may actually be happier getting together with your friends, a new study finds.

Brain circuitry underlying dissociative experiences

Scientists identified key brain circuitry that plays a role in the mysterious experience called dissociation, in which people can feel disconnected from their own body and from reality.

Reprogramming brain cells enables flexible decision-making

Humans, like other animals, have the ability to constantly adapt to new situations. Researchers have utilized a mouse model to reveal which neurons in the brain are in command in guiding adaptive behavior. Their new study contributes to our understandi…

Older people with early, asymptomatic Alzheimer’s at risk of falls

Older people without cognitive problems who experience a fall may have undetected neurodegeneration in their brains that puts them at high risk of developing Alzheimer’s dementia, according to a new study.

Key role of immune cells in brain infection

Researchers have identified the specific type of immune cell that induces brain inflammation in herpes simplex virus (HSV) encephalitis. Crucially, they have also determined the signalling protein that calls this immune cell into the brain from the blo…

Real neurons are noisy: Can neural implants figure that out?

Signals sent from the retina to the brain have a lot of background noise, yet we see the world clearly. Researchers show that to achieve visual clarity the brain must accurately measure how this noise is distributed across neurons when processing the s…

New dopamine sensors could help unlock the mysteries of brain chemistry

Scientists developed dLight1, a single fluorescent protein-based biosensor. This sensor allows high resolution, real-time imaging of the spatial and temporal release of dopamine in live animals. Now, the team expanded the color spectrum of dLight1 to Y…

Risk gene for Alzheimer’s has early effects on the brain

A genetic predisposition to late-onset Alzheimer’s disease affects how the brains of young adults cope with certain memory tasks. Researchers find are based on studies with magnetic resonance imaging in individuals at the age of about 20 years. The sci…

Immune system affects mind and body, study indicates

Researchers have discovered that a molecule produced by the immune system acts on the brain to change the behavior of mice.
