Human Cortical Electroencephalography (EEG) Rhythms during the Observation of Simple Aimless Movements: A High-Resolution EEG Study
2002
NeuroImage
Preserved Fulltext
In the present high-resolution electroencephalographic (EEG) study, we computed event-related desynchronization and synchronization (ERD/ERS) of ␣ (about 10 Hz) and  (about 20 Hz) rhythms in association ...
Finally, the pattern of hemispherical cortical rhythmicity did not support a "simple concentration" of movement observation functions in the left or right hemisphere. © 2002 Elsevier Science (USA) ...

The hippocampus, a hub of activity for a variety of important cognitive processes, is a target of increasing interest for researchers and clinicians. ...
However, the decrease in MEG signal-to-noise ratio as a function of source depth implies that the utility of MEG for investigations of deeper brain structures, including the hippocampus, is less clear. ...
Previously, Cornwell et al. (2008,b) had reported a similar effect in the left hippocampus when comparing goal-directed to aimless movements in a virtual pool. ...
