University College London May 7 2025 A decades-old challenge in neuroscience has been solved by harnessing artificial intelligence (AI) to identify the electrical signatures of different types of brain cells for the first time, as part of a study in mice led by researchers from UCL. Brains are made up of many different types of neurons (nerve cells in the brain), each of which are thought to play different roles in processing information. Scientists have long been able to use electrodes to
