Imaging probe to visualize Alzheimer’s disease-related gamma-secretase in the brain
Scientists at the Massachusetts General Hospital (MGH) have developed a molecular imaging probe to reveal Alzheimer’s disease (AD)-related γ-secretase in rodents and macaques with translational potentials in humans. γ-Secretase is a key player in the etiology of AD and a…

New dopamine sensors could help unlock the mysteries of brain chemistry
In 2018, Lin Tian and her team at UC Davis Health developed dLight1, a single fluorescent protein-based biosensor. This family of highly specific sensors detects dopamine, a hormone released by neurons to send signals to other nerve cells. When combined…

Researchers identify key role of immune cells in brain infection
A new study has detailed the damaging role played by the immune system in a severe brain condition most commonly caused by the cold sore virus. Researchers have identified the specific type of immune cell that induces brain inflammation in…

Site of male sexual desire uncovered in brain
The locus of male sexual desire has been uncovered in specific regions of brain tissue where a key gene named aromatase is present, reports a new Northwestern Medicine study in mice. The gene regulates sexual behavior in men, and thus…

Study sheds light on brain mechanism activated by uncertainty
Tel Aviv University researchers examined the brain’s reactions in conditions of uncertainty and stressful conflict in an environment of risks and opportunities. The researchers identified the areas of the brain responsible for the delicate balance between desiring gain and avoiding…

Individuals with high level of schizotypal traits exhibit altered brain structural and functional connectivity
Schizophrenia is a complex psychiatric disorder involving a wide range of cognitive, emotional, and social function impairments and altered brain structure. Recent findings suggest a continuum approach: that continuous symptoms and psychiatric disorder related traits can be integrated as risk…

Tapping into the vast amount of nonconscious information continually represented in the brain
By using a combination of artificial intelligence and brain imaging technology, researchers have discovered that humans can be trained to rationally use the unconscious contents of their mental processes. The study, published in the journal Nature Communications, could open the…

Bacteria in the gut have a direct line to the brain
With its 100 million neurons, the gut has earned a reputation as the body’s “second brain”—corresponding with the real brain to manage things like intestinal muscle activity and enzyme secretions. A growing community of scientists are now seeking to understand…

Brain cell types identified that may push males to fight and have sex
Two groups of nerve cells may serve as “on-off switches” for male mating and aggression, suggests a new study in rodents. These neurons appear to send signals between two parts of the brain—the back tip, or posterior, of the amygdala…
