Seminar topics 2018: Sessions for NEUR3045/G045/M045 students

Sign up for one of the seminars by sending an e-mail to a.stockman@ucl.ac.uk, giving also second and third choices. Seminars will be assigned on a first-come, first-served basis. Topics already assigned are followed by the initials of the presenter in red.

Presentations should each be about 10 minutes in length. Please time your presentations before you give them. A data projector will be available in the room. If you need any further help with references, please e-mail the seminar organizers.

The seminar dates are listed in the timetable. Scheduling will depend on student numbers and choices.

Titles already assigned will be denoted by the initials in red.
