    Author: Chen Y, Huang X, Yang H, Ren G, Chen Y, Yue C.
    Journal: Neuroreport; 2007 Dec 03; 18(18):1951-5. PubMed ID: 18007193.
    Abstract:
    Event-related potentials (ERPs) technique was used to examine brain activity related to task interference during event-based prospective memory. The behavioral data indicated that there existed task interference. Data from ERPs record on non-prospective memory trials suggested that there were significant differences in the time windows of 200-300, 300-350, and 350-400 ms after the onset of stimulus. The ERP difference wave showed the maximum amplitude over the central site (Fz) with a peak latency of 250 ms (N250). The topographical map in the time window of 200-300 ms indicated that the components reflected activation mainly in the frontal lobe. The results seemed to support preparatory attentional processes and memory processes theory and revealed that frontal lobe was involved in monitoring, which caused task interference effect.
