Abstract
Differential gamma-band responses to word and pseudoword
presentation cannot be an artifact of power changes in lower
frequency bands because analysis of low frequency bands did not
reveal such changes. Linguistic units, such as phonemes and
morphemes, are well-defined entities. Thus, there is no motivation
for the criticisms raised in Mueller & Jokeit's commentary.
