Do hand-puck buttons generate Event Manager events?

1
In the MRI scanner, when a subject presses a button on a hand puck, does that
generate an event that is store by the Event Manager and can be retrieved by
GetChar?

GetButtons seems to work like KbCheck in that it gives the current state of the
buttons or keyboard respectively and, unlike GetChar, does not retrieve buttons
presses that occurred since the last GetButtons call. But maybe the buttons
still generate events similar to pressing the function keys in test mode of
GetButtons?
