Keys may be signed out from Lisa Sivertsen in the main Neuroscience office in Kennedy (room 908). You should arrange with her to pick up keys before you need to start your experiments and keys should be returned within one week of the completion of the experiments.
As of August, 2010, each PI or lab will have their own access code that is linked to your ID badge. These are provided byt the Animal Institute. You should contact them to arrange access to Kennedy Center housing facilities well in advance of the date that access will be needed.
