title: Neural correlates of the formation and realization of delayed intentions.
abstract: Prospective memory (PM) can be thought of as the ability to successfully form and later realize intentions that must be delayed over some period of time. In this study, event-related brain potentials were used to explore the neural activity associated with the formation and realization of an intention. Greater negativity over the frontal-polar region was associated with intention formation trials in which the intention was later realized. On PM cue trials, an N300 was associated with the detection of a cue. For PM cue trials, a late positive complex was observed that might have reflected the retrieval of an intention from memory, and a frontal slow wave was observed that might have reflected the activity of a neural system that supported disengagement from the ongoing activity when the cue was detected.
