Abstract

En 中文

• Pre-source alpha differences predict the subjective intensity of the subsequent “Aha” experience. • Perceptual insight is associated with differences in N2 and LPC components during successful recognition. • Neural activity distinguishes hidden from unhidden perceptual processing over time. • Perceptual mode and perceptual validity are dissociable at both behavioral and neural levels.
