PHYSCI CM123 · Dis 1B
Neurobiology of Sleep
Fall 2026 · An unnamed TA · 4 units
Also listed as NEUROSC CM123 (waitlist, 35 of 35 enrolled, limited): the same class, and each department holds its own seats and its own grade history.
Watching is the one thing here that needs an account, because an alert needs somewhere to go. Everything else on this page works signed out.

- Closed
- Its lecture reads closed (70 of 70 · 3 over enrolled): you attend both, so this seat is not one you can take while that holds. There is no waitlist either, so the only way in is somebody dropping the lecture.
Tell dibs what you have already taken and this line will say which of these you have. Your list.

From the registrar limited by major
Enrollment is limited to Physiological Science majors on the priority, first, and second enrollment passes. Any student may enroll beginning September 15, 2026, space permitting.
The limit applies to the earlier enrollment pass. Dibs still counts this class as one you can take, because it opens up, but on first pass it may not be yours yet. This class is also Physiological Science Majors, which the pass does not lift.
When it meets
Meets: R 5:00pm-5:50pm

What students say
Dibs measures outcomes: grades, seats, how fast it fills. For what the class is actually like to sit in, BruinWalk has the reviews.
Enrollment over time
A dot is a reading where something moved: the seat count, the status, or the waitlist. The last one is the most recent sweep, moved or not. The line holds flat between dots because that is what the readings say: it did not drift, it held and then jumped. The ticks along the bottom are the hours Dibs recorded reading this section, which is how a flat run says "checked, unchanged" rather than "nobody looked". It only keeps those from 25 August, so the ruler is shorter than the line for now. Both start when Dibs did rather than reaching back before it existed.
