One fundamental question in neuroscience is how the brain processes and stores information. As the information-processing elements in the brain, neurons communicate via specialized connections called synapses.

New connections between brain cells emerge in clusters in the brain as animals learn to perform a new task, according to a study published inNature on February 19 (advance online publication).

Brain-computer interface (BCI) technology aims at helping severely motor disabled people like the physicist Stephen Hawking, due to diseases such as amyotrophic lateral sclerosis, or spinal cord injury, etc.

In collaboration with Vincenzo De Paolaa‘s lab at MRC in London, Sen Songa€?s lab recently discovered that axonal bouton dynamics are increased in aging mouse cortex rather than decreased.
