Two recent monkey studies demonstrate that feedforward processing in the visual system is reflected by activity in the 40-90Hz gamma band, whereas feedback is reflected by activity in the 5-18Hz alpha and beta band. These findings can be applied to interpret human electrophysiological activity in complex visual tasks.
两项最近的猴子研究表明，视觉系统中的前馈处理由 40-90Hz 的伽马波段活动反映，而反馈则由 5-18Hz 的阿尔法和贝塔波段活动反映。这些发现可以应用于解释人类在复杂视觉任务中的电生理活动。
