摘要

Functional dissociation of EEG theta rhythms between prefrontal and visual cortices and their synchronization during sustained attention Over a decade, coherent theta rhythms (4-12 Hz) within the cerebral cortex have been believed to facilitate information pro- cessing by bridging distal brain regions during a task situation. For example, the theta synchrony between prefrontal cortex (PFC) and visual cortex (VC) has been known to be associated with enhanced task performance and attention. Recently, this conceptual frame- work has been mitigated by a wayward behavior of theta power in VC during sustained attention task: Spyropoulos et al. (2018) observed that the evoked theta in VC decreased as the demands for the visual attention raised in a visual task. Likewise, Stitt et al. (2018) observed that the theta power in high-order VC became lessened by arousal but maintained its synchrony with the PFC in a sustained attention task. These inconsistent behaviors of theta rhythms suggest that theta rhythms in PFC and VC might be differ- ently involved during a task situation. In order to enunciate their different roles, we analyzed EEG signals from mouse PFC and VC during visual Go/No-Go task with respect to short-term task perfor- mance. The short-term task performance was assessed by the ratio of correct trials obtained through a moving window of 10 trials. We found that PFC and VC theta behaved in an opposite way: PFC.
