Abstract :
Summary form only given. We are interested in the endogenous negativity of the earlier negative component (designated NA) for observing some aspects of cognitive processes. We recorded the visual NA magnetic field with a 204-channel whole-scalp SQUID gradiometer and estimated the equivalent current dipoles (ECD) to clarify the source localization of NA.
