Spatiotemporal imaging of cortical activations during verbal memory encoding tasks

The spatiotemporal imaging of cortical activations during memory encoding was conducted by analyzing event-related potentials (ERPs) recorded from 11 healthy subjects who participated in word encoding tasks using rote strategy. Cortical potentials were imaged noninvasively from scalp ERPs. Different levels of brain activation were found in the left inferior prefrontal, left medial temporal and left parietal lobes with different latencies after onset of event. It is concluded that these regions work jointly across both spatial and temporal domains to promote verbal memory formation.
