A new 3D protein structure helps researchers to better understand the rapid action of neurotransmission.
Sweet tasting foods don't only trigger the taste buds, they also switch on a neurological pathway that begins in the gut. In the intestines, signals of sugar ingestion travel to the brain, sparking an appetite for more sweet foods. However, this pathway only responds to sugars, not artificial sweeteners.

Using machine learning, researchers have created a comprehensive brain map that links different groups of neurons to specific behaviors in fruit fly brains. The study, published in Cell, reports the AI used more than 225 days of video footage to help create the map. Left in human hands, the work would have taken an estimated 3,800 years to complete.
Stimulating mouse neurons in a dish lead to a build-up to fatty acids and lipid particle release. Astrocytes engulfed the particles and increased genetic activity associated with detoxification.
Researchers have been able to map neural activity in live mice with the aid of a tiny microscope mounted on the animals' heads. The findings provide insight into the neurobiology of social behavior.
Study could help explain how our cells deteriorate over time.
HHMI researchers used electronic microscopy technology to generate a high resolution digital snapshot of the adult fruit fly brain.
Restricting calories and eating only during the most active part of the day helped extend the lifespan of mice.
Researchers have identified how two types of neurons divide the labor to plan and initiate movements.
Microscopy technology allows researchers to discover new connections in brain areas associated with memory and learning in fruit flies.
Glial cells and radial astrocytes might control the decision to give up swimming against the current in Zebrafish.
The ion channel TRPC5 acts as a molecular cold sensor in teeth. Researchers report the TRPC5 could be a new target to help treat pain from toothaches and cold sensitivity.
