Synchronized oscillatory activity in the gamma frequency range has been proposed as a neuronal mechanism for various cognitive processes, ranging from perceptual binding (Singer, 1999) to motor control (Schoffelen et al., 2005). In a recent paper in Neuron, Yuval-Greenberg et al. (2008) claim that induced gamma oscillations recorded by scalp electroencephalography (EEG) reflect miniature saccades instead of cognitive or neuronal processes. Combining high-precision eye tracking with EEG recordings, Yuval-Greenberg et al.
