By tagging neurons with molecular "barcodes," researchers have mapped connections among thousands of neurons in the mouse brain with unprecedented speed and resolution. The approach could expand ...

Even the simplest networks of neurons in the brain are composed of millions of connections, and examining these vast networks is critical to understanding how the brain works. An international team of ...

Not all brain cells are found in the brain. For example, a team at Caltech has identified two distinct types of neurons in the abdomens of mice that appear to control different aspects of digestion.
