Memory-based visual mismatch negativity to orientation changes

Abstract

Event Abstract Back to Event Memory-based visual mismatch negativity to orientation changes Piia Astikainen1* 1 Department of Psychology, University of Jyväskylä, Finland There is growing evidence for the mismatch negativity not only to auditory changes (MMN) but also to visual changes (vMMN). However, if the vMMN to visual deviant stimuli is elicited with support of the sensory memory of the previous standard stimuli, as the auditory MMN is, has remained largely unsettled. We have explored this issue in humans (scalp recordings) and animals (intracranial recordings) by measuring the vMMN for changes in orientation. In rabbits, the oddball paradigm applied with the deviant-alone control condition revealed the memory relatedness of the mismatch response (Astikainen et al., 2000, Neuroreport, 11, 1515-1517). In a subsequent study (Astikainen et al., 2005, Exp. Brain Res., 160,189-193), the experimental variation of the inter-stimulus interval further showed that the sensory memory in rabbits resembled the memory in humans in its shorter duration relative to its auditory counterpart. In humans, our data from the deviant-alone condition (Astikainen et al., 2004, Neurosci. Lett., 368, 231-234) as well as from the more stringent equal probability control condition (Astikainen et al., 2008, Eur. J. Neurosci., 28, 2319-2324) suggested that the elicitation of the vMMN was relying on a memory-based process. In addition, its elicitation seemed to be restricted to the duration of the active memory trace. That is, the vMMN was elicited with the 400-ms, but not with the 1100-ms, inter-stimulus intervals corresponding well to previous behavioral measures of the duration of the visual sensory memory.
