Sorting out additions to the understanding of cognition during sleep

Abstract

The target articles by Hobson et al., by Solms, and by Nielsen can be combined to further our understanding of the neurological basis of dreaming during REM and, notably, NREM sleep. Revonsuo adds to our understanding of the function of dreams from the perspective of behavioral biology but overstates its importance. Vertes & Eastman fail in their effort to discount memory enhancement as a function of REM sleep.[Hobson et al.; Nielsen; Revonsuo; Solms; Vertes & Eastman]
