Gamma oscillations in the brain are thought to 'bind' spatially distributed cells, a function that is probably important in perception, attentional selection and memory. However, it is unclear why the frequency of gamma oscillations varies substantially across space and time. Here, the study of the frequency of gamma oscillations in the CA1 area of the hippocampus suggests that variations in gamma frequency may be important for routeing information in the brain.
