The neural circuitry underlying the executive control of auditory spatial attention.

摘要: Although a fronto-parietal network has consistently been implicated in the control of visual spatial attention, that guides attention auditory domain is not yet clearly understood. To investigate this issue, we measured brain activity using functional magnetic resonance imaging while participants performed cued task. We found orienting activated medial-superior distributed network. In addition, cue-triggered increases sensory cortex prior to occurrence an target, suggesting attentional operates part by biasing processing favor expected target stimuli. Finally, exploratory cross-study comparison further indicated several common frontal and parietal regions as being involved both attention. Thus, present findings only reveal areas underlying endogenous modality, but also suggest different modalities enabled some common, supramodal neural mechanisms.
