The slides from the UCL computational psychiatry course are now online. There, you can find all slides as well as the audio-files from all the speakers. The talks were all excellent and are worth listening to. My slides, etc, are – of course – also available there. You can find everything here: https://sites.google.com/site/comppsychcourse/2015schedule.
We also just published a new paper on arithmetic learning and tDCS in the European Journal of Neuroscience. More details are available in my post here: http://v1.tobiashauser.ch/papers/arithmetic-learning-modulated-by-tdcs/.
