Entrance to the Lab The Brain & Behaviour Lab is located on the 4th floor of the MF-building (A-wing). The easiest way to find it is to take the stairs or elevator located at the front entrance of the MF-building. When you are on the 4th floor, take the hallway that takes you to the A-wing. The entrance to the lab is the first room that you find on your left-hand side, with glass walls:         The door is open from 09:00 to 17:00 on weekdays. If you want to enter outside of this time window, you need a [LINK TO KEYCARD PAGE]. After entering, you will see the waiting area (MF A-431):         Participants can wait here until the researcher comes and accompanies them to their lab. When advertising your experiment on Sona or elsewhere, we advise you to mention the room number of this waiting area (MF A-431) in addition to the name "Brain & Behaviour Lab". If you just mention the room that you are using for your experiment, for example B-449a, it will be harder for participants to find. This is because most rooms are located in the back of the lab.
