The brain, traffic and nano-circuits -- e-Science takes on major challenges

...eractions between networks of neurons that lead to thoughts and behaviour. The techniques are time-consuming, difficult and expensive, but researchers rarely record their data or models so that they can be used by other labs or research groups. CARMEN will help maximise the output from investment in brain sci...

Bhatia and Hui's first thoughts about how to solve this cellular space and time problem involved another children's game: plastic puzzles with squares that slide around on a grid. They wondered if they could put different cells on each square and then move them around. This ide...

Brain tissue reveals possible genetic trigger for schizophrenia
