EEG Theta, Memory, and Sleep

  • Wolfgang Klimesch


In contrast to the alpha rhythm, which is the dominant large scale oscillation in the human EEG, most of what is known about the theta rhythm stems from animal research. Therefore, the most important properties and the functional meaning of the hippocampal EEG will be reviewed first. Research with human subjects then will be reported, which indicates that an event-related increase in theta power is associated with increasing memory demands in a similar way as was found in animal research for the hippocampal EEG. Finally, it will be shown that sleep is important for memory consolidation. The involvement of the hippocampal formation will be discussed.
