Dear Comp-Neuro mailing list members, The fourth edition of the Canadian Computational Neuroscience Spotlight (CCNS) <https://ccnsmeeting.ca/#04-ccns-2023-program>, taking place October 5-6 online via Crowdcast (register here <https://www.crowdcast.io/c/ccnsv4>), is fast approaching, as is our first deadline for abstract submission for trainee talks. *To be considered for a spotlight presentation, submit your abstract <https://docs.google.com/forms/d/e/1FAIpQLSeev-EA5ccwKapzRV43xD4NfDYGyDeAiWpT...> by September 1 at 5 p.m. EDT*; late abstracts will be accepted until September 13 at 5 p.m. EDT but will only be considered for parallel talks as space allows. As a point of clarification, *you do not need to be Canadian, or be located at a Canadian institution, to submit an abstract*: while the meeting's namesake comes from its original impetus in the early stages of the pandemic, we have fully embraced the international nature of virtual meetings, including in these trainee talks. We invite submissions from trainees at all levels, and anticipate that all submissions reasonably falling under the broad banner of "computational neuroscience" will be accepted unless the demand far exceeds our expectations. Please feel free to reach out to the organizing committee if you have any questions. Sincerely, The CCNS Organizing Committee: Scott Rich <http://scottrich.strikingly.com/>, Ph.D. Research Fellow, SickKids Research Institute.
