Electrophysiological correlates of change detection.
To identify electrophysiological correlates of change detection, event-related brain potentials (ERPs) were recorded while participants monitored displays containing four faces in order to detect a face identity change across successive displays. Successful change detection was mirrored by an N2pc component at posterior electrodes contralateral to the side of a change, suggesting close links be...
متن کاملElectrophysiological Correlates of Change Detection during Delayed Matching Task: A Comparison of Different References
Detecting the changed information between memory representation and incoming sensory inputs is a fundamental cognitive ability. By offering the promise of excellent temporal resolution, event-related potential (ERP) technique has served as a primary tool for studying this process with reference of the linked mastoid (LM). However, given that LM may distort the ERP signals, it is still undetermi...
متن کاملBehavioral and Electrophysiological Correlates of Change Blindness (invited Paper)
Although the ability to notice a change in the visual scene has been used as an investigative tool to gain new insights on visual system mechanisms, it has recently become an issue itself. In the last decade, many studies have addressed the flip side of change detection, namely the change blindness phenomenon. Change blindness refers to functional blindness for an otherwise visible change in th...
متن کاملElectrophysiological correlates of the efficient detection of emotional facial expressions.
Behavioral studies have shown that emotional facial expressions are detected more rapidly and accurately than are neutral expressions. However, the neural mechanism underlying this efficient detection has remained unclear. To investigate this mechanism, we measured event-related potentials (ERPs) during a visual search task in which participants detected the normal emotional facial expressions ...
متن کاملNeural correlates of olfactory change detection.
Detecting changes in a stream of sensory information is vital to animals and humans. While there have been several studies of automatic change detection in various sensory modalities, olfactory change detection is largely unstudied. We investigated brain regions responsive to both passive and active detection of olfactory change using fMRI. Nine right-handed healthy, normosmic subjects (five me...
