2.2.2. Cue light conditioning in rodents
In addition to driving LED intensity with the Arduino, it can be
used to relay trigger signals from external sources or to generate
the trigger directly from the code. One example of this kind of use,
is to turn on and off a cue light based on the behavior of the mouse
in the experimental paradigm of Malkki et al. (2010). The mouse in
the “operant nose poke task” has to collect a sucrose pellet while
