 Abstract: This chapter describes how adaptation over short time frames (seconds) can be combined with brain imaging to study visual representations in the primate brain. The fMRI-adaptation approach, developed by Grill-Spector and her colleagues, exploits the fact that the fMRI response is reduced by repeated presentation of the same stimulus, which they attribute to the suppression of stimulus-specific neurons. Therefore, if a change in a stimulus dimension causes an increased response or ‘rebound’ from adaptation, then the population of neurons must be selective for, or code, that property. If adaptation remains constant across a change, then the population coding must be invariant to that property.
