My colleagues at the Department of Neuroscience and Biomedical Engineering at Aalto University are organizing the Brain Twitter Conference. It takes place on Twitter on the 20th of April, with an impressive list of speakers. Talks and keynotes will be delivered under the #brainTC hashtag.

While the idea of a Twitter conference may sound like a gimmick, it should be taken seriously – not as a substitute but as something new. There are no coffee breaks or conference dinners for socializing, but anyone can attend for free. And, even better, because the tweets will remain available, a kind of time travel becomes possible – one can revisit any talk, any discussion, and any debate at will. The conference becomes frozen in time.
