In the current study we measure auditory event-related brain
potentials (ERP) in a rhesus monkey (Macaca mulatta) using
the mismatch negativity component (MMN) as an index of (the
violation of) rhythmic expectation (cf. Honing, 2012). First,
we tested whether an MMN can be elicited in rhesus monkeys
at all (using deviant tones at random positions in the sound
stream). Second, we investigated whether an MMN can be
elicited for omissions (by inserting gaps at random positions
in the sound stream). Consequently, we probed the presence
of beat induction by selectively omitting parts of a musical
rhythm (randomly inserting gaps at the first position of a
musical unit, i.e. the ‘downbeat’).
