Summary nSurvey of papers published in bioRxiv uIn terms of disciplines, neuroscience is growing remarkably uMore than 40% of submitted manuscripts may eventually be published in journals. pFor those that were published, it took about half a year from the first submission to bioRxiv for publication, and the difference between the fields was not that great. 2
