A new lab member can obtain a locker in the hallway by contacting Neuro Ops (neuro_ops@hms.harvard.edu) and asking for an available locker near the lab. Steve or Josh will give you the locker number together with a three-digit combination for the lock.
Turn right three times. Stop at First Digit.
Turn left one full turn passing 1st number and stop at Second Digit.
Turn right and stop at Third Digit and open. Might need to rotate the dial to do so.
