While the dual-stream model (dorsal “Where” vs. ventral “What”) is well-established in the auditory system, the top-down mechanisms controlling these streams remain underexplored.
In the visual system, the Frontal Eye Field (FEF) directs spatial attention, whereas the Inferior Frontal Junction (IFJ) controls object-based attention (Bedini & Baldauf, 2021).
This project investigates whether this prefrontal control architecture operates supramodally, extending to the auditory domain. Using rs-fMRI connectivity data from the Human Connectome Project, the connectivity analysis reveals a clear double dissociation: the FEF preferentially connects to the auditory spatial where-stream, while the IFJ selectively targets the identity-based (semantic) what-stream.
