1.3 Hypothesis, A supramodal organization
We hypothesize that the functional connections of the auditory what and where streams are supramodal within the prefrontal cortex both being coordinated through top-down attention mechanisms from the FEF and IFJ.
In detail:
- The seeds of the Frontal Eye Field (FEF) should preferentially connect to the auditory where-stream
- The seeds of the Inferior Frontal Junction (IFJ) should preferentially connect to the auditory what-stream
Because both FEF and IFJ are known to direct top-down attentional control in the visual domain, we propose that they may play an analogous role for auditory attention as well along the where and what pathways.
In summary we test whether the prefrontal cortex shows the same division of attention direction in the auditory stream as is found in the visual stream.
