Molecular imaging identifies brain changes in response to food cues; offers insight into obesity interventions

Molecular imaging with 18F-flubatine PET/MRI has shown that neuroreceptors in the brains of individuals with obesity respond differently to food cues than those in normal-weight individuals, making the neuroreceptors a prime target for obesity treatmen…

Poor sense of smell linked to increased risk of depression in older adults

In a study that followed more than 2,000 community-dwelling older adults over eight years, researchers say they have significant new evidence of a link between decreased sense of smell and risk of developing late-life depression.

A subtype of depression identified

Using surveys, cognitive tests and brain imaging, researchers have identified a type of depression that affects about a quarter of patients. The goal is to diagnose and treat the condition more precisely.

Chronic stress-related neurons identified

Researchers have identified a group of nerve cells in the mouse brain that are involved in creating negative emotional states and chronic stress. The neurons, which have been mapped with a combination of advanced techniques, also have receptors for est…

Unraveling the connections between the brain and gut

Engineers designed a technology to probe connections between the brain and the digestive tract. Using fibers embedded with a variety of sensors, as well as optogenetic stimulation, the researchers could control neural circuits connecting the gut and th…

Cuttlefish brain atlas created

Anything with three hearts, blue blood and skin that can change colors like a display in Times Square is likely to turn heads. Meet Sepia bandensis, known more descriptively as the camouflaging dwarf cuttlefish. Over the past three years, neuroscientis…

Restoring the blood-brain barrier?

Scientists discover a treatment in mice to repair the blood-brain barrier, which is key to brain health.

Everyone’s brain has a pain fingerprint — new research has revealed for the first time

New research has revealed everyone’s brain has a ‘pain fingerprint’ that varies from person to person.

Brain receptor patterns separate sensory and cognitive networks

Receptor patterns define key organizational principles in the brain, scientists have discovered.
