However, recent visual task studies found that selective attention attenuates stimulus-related \u03b8 power in the visual cortex, suggesting a functional dissociation of cortical \u03b8 oscillations. To investigate this contradictory behavior of cortical \u03b8, a visual Go\/No-Go task was performed with electroencephalogram (EEG) recording in C57BL\/6J mice. During the No-Go period, transient \u03b8 oscillations were observed in both the frontal and visual cortices, but \u03b8 oscillations of the two areas were prominent in different trial epochs. By separating trial epochs based on subjects\u2019 short-term performance, we found that frontal \u03b8 was prominent in good-performance epochs, while visual \u03b8 was prominent in bad-performance epochs, exhibiting a functional dissociation of cortical \u03b8 rhythms. Furthermore, the two \u03b8 rhythms also showed a heterogeneous pattern of phase-amplitude coupling with fast oscillations, reflecting their distinct architecture in underlying neuronal circuitry. Interestingly, in good-performance epochs, where visual \u03b8 was relatively weak, stronger fronto-visual long-range synchrony and shorter posterior-to-anterior temporal delay were found. These findings highlight a previously overlooked aspect of long-range synchrony between distinct oscillatory entities in the cerebral cortex and provide empirical evidence of a functional dissociation of cortical \u03b8 rhythms.<\/jats:p>","DOI":"10.1523\/eneuro.0248-19.2019","type":"journal-article","created":{"date-parts":[[2019,11,4]],"date-time":"2019-11-04T18:22:59Z","timestamp":1572891779000},"page":"ENEURO.0248-19.2019","source":"Crossref","is-referenced-by-count":23,"title":["Functional
