MMN/MMR refer to responses during an [oddball paradigm](https://en.wikipedia.org/wiki/Oddball_paradigm). The typical arrangement of this sort of paradigm is to have a sequence of stimuli, for example, a sequence of tones of one frequency, followed by either the same tone (standard) or a different tone (oddball).

[For EEG, they are the same thing](https://en.wikipedia.org/wiki/Mismatch_negativity). Mismatch negativity is a particular response in the EEG observed as the difference in response to an "oddball" compared to the same stimulus when it is a standard.

"Mismatch response" is a more general term that would include, for example, an increase (or simply a change) in neuronal firing in response to the oddball vs. standard, or a change in functional connectivity, etc.
