Button boxes

We have two 4-button optical button boxes for use with the MEG. Usually all 8 outputs will be connected to the trigger box in the stimulus cabinet. The channels used are 9-16. These boxes can be used with the table insert for the MEG seat.

EN also supplied us with two button panels, which work in a different way. There's no button but a strip of material that has to bu pushed down. The normal button boxes will click when switching, but these EN panels don't. They also have a tendency to come on again if the strip is pushed deeper, producing the sequence on-off-on-off-on for a single press.
