Abstract

A mental representation of the location of an object can be constructed using sensory information selected from the environment and information stored internally. Human electrophysiological evidence indicates that behaviorally relevant locations, regardless of the source of sensory information, are represented in alpha-band oscillations suggesting a shared process. Here we present evidence from human subjects of either sex for two distinct alpha-band based processes that separately support the representation of location, exploiting sensory evidence sampled either externally or internally.
