Non-invasive single-trial monitoring of human movement-related brain activation based on DC-magnetoencephalography.

abstract：:The neural foundation of age-related declines in prospective memory was explored using event-related brain potentials (ERPs). Consistent with previous research, a decline in the efficiency of prospective memory was observed in older adults that reflected a decrease in veridical prospective responses and an increase in...
