The International Neuroscience Olympiad (INO) is a youth-run neuroscience competition involving research-paper interpretation, scientific data analysis and critical thinking. The official homepage states that registration for the 2026–27 Opens is closed. This is the registration status for that intake, not a statement that all later rounds have concluded. No subsequent intake's application dates were verified as of November 4, 2026.
The registration page charges USD10 for direct registration and offers hardship waivers. Its officially linked ASEEDER partner handles the countries specifically listed there and sets separate fees and financial-assistance policies. The central page's eligibility wording is inconsistent: it says one of enrollment or age requirements, permits age-eligible college freshmen, and gives an age cutoff of 18 or younger on December 30, 2026, while the homepage says ages 13–18. ASEEDER lists grades 9–12/Years 10–13. These differences remain unresolved.
Schedule checked November 4, 2026: the central 2026 exam overview gives October 25/26 in one paragraph but October 24/25 in the Opens section. It lists January semifinals and February–March finals with exact dates to be determined. The officially linked ASEEDER page instead explicitly dates the Open round October 26, 2026, semifinals January 18, 2027, and finals April 2027, with exact final dates to be determined. Its registration rule is two weeks before the relevant exam, not a universal September 30 deadline. The former catalog's September 30, 2026 cutoff was not reverified and is retained here only as unverified historical catalog information. No exact central exam dates are asserted while its published dates conflict.
