At the moment I am looking at the visual part of the brain (the visual part of the cortex to be precise – so the more evolved part of the brain that’s right on the surface). This should help us understand how the information about the visual targets (e.g. vertical stripes versus almost-vertical stripes) in the computer game is passed along by the neurons.
In future, I’d also quite like to look at some ‘control’ areas of the cortex though. They’re in the front of the brain and help you decide what to do next, learn rules, predict consequences of your actions, that kind of thing. So those areas would be really interesting to mess with while the mice are learning the game and starting to understand its rules.
