Finding gamma.
Neuronal gamma-band synchronization is central for cognition. Respective studies in human subjects focused on a visually induced transient enhancement of broadband EEG power. In this issue of Neuron, Yuval-Greenberg et al. demonstrate that this EEG response is an artifact of microsaccades, raising the question of whether gamma-band synchronization can be assessed with EEG.
