Salmi (2007)

Core argument: Spatial attention orienting in audition and vision recruits a largely overlapping frontoparietal network — including the same superior and inferior parietal lobule and posterior prefrontal areas (MFG/FEF region) — confirming that spatial attention in the auditory domain uses the same supramodal cortical architecture as visual attention.

Methods:

• 9 healthy right-handed subjects (5 female; 24–35 years)
• Block-design fMRI (3T GE Signa scanner, TR = 2800 ms)
• Four tasks: auditory orienting, auditory maintenance, visual orienting, visual maintenance
• Participants selectively attended to sounds or pictures at left or right locations, shifting focus between locations (orienting) or holding it centrally (maintenance)

Key results:

• Common to both modalities (orienting > maintenance): Superior parietal lobule (SPL) bilaterally, inferior parietal lobule, and posterior prefrontal cortex (MFG/SFG — i.e., FEF region) activated for both auditory and visual orienting
• Auditory > Visual: Inferior parietal and prefrontal (MFG) activations were stronger for auditory than visual orienting — suggesting the FEF/MFG region contributes more to auditory spatial orienting than to visual
• Visual > Auditory: Superior parietal and occipital cortex showed stronger activation in visual orienting tasks, consistent with modality-specific visual spatial processing
• Thalamic and cerebellar activations were observed specifically in auditory orienting and maintenance

Direct connection to thesis:
This paper is the predecessor to Salmi et al. (2009). Where Salmi (2009) showed FEF activates for attention shifting in audition, Salmi (2007) established that even basic spatial orienting and maintenance in audition recruits the same prefrontal-parietal network as vision — including the FEF/MFG region.

Relevance to thesis:

• Cite in §2.2.3 (“the same group had previously shown that shifting spatial attention in audition and vision recruits overlapping IPS/SPL and FEF/PMC regions”) — this is exactly what Salmi (2007) found
• Together with Salmi (2009), it establishes FEF as a supramodal spatial attention hub active in both vision and audition, directly supporting the thesis hypothesis
