“participants selectively attended to tone streams at the left or right, and occasionally shifted their attention from one stream to another as guided by a centrally presented visual cue.” (Salmi et al., 2009, p. 155)
“Loudness deviating tones (LDTs)” (Salmi et al., 2009, p. 155)
“LDTs activated the right temporo-parietal junction (TPJ), posterior parts of the left inferior/middle frontal gyrus (IFG/MFG), ventromedial parts of the superior parietal lobule (SPL), and left frontal eye field/premotor cortex (FEF/PMC).” (Salmi et al., 2009, p. 155)
“Top-down controlled cue-guided attention shifts (CASs) activated bilateral areas in the SPL, intraparietal sulcus (IPS), FEF/PMC, TPJ, IFG/MFG, and cingulate/medial frontal gyrus, and crus I/II of the cerebellum” (Salmi et al., 2009, p. 155)
“in audition top-down controlled and bottom-up triggered shifting of attention activate largely overlapping temporo-parietal, superior parietal and frontal areas.” (Salmi et al., 2009, p. 155)
“Only a few previous auditory fMRI studies have investigated brain activity underlying top-down controlled shifting of spatial attention (Shomstein and Yantis, 2006; Salmi et al., 2007a; Wu et al., 2007).” (Salmi et al., 2009, p. 156)
“Participants selectively attended to tones at the left or right as indicated by a visual cue composed of green and red arrowheads and occasionally shifted their attention between the two tone streams when the cue color changed” (Salmi et al., 2009, p. 156)
“reaction times” (Salmi et al., 2009, p. 156)
“rate of missed responses to a change in duration of the to-be-attended tones” (Salmi et al., 2009, p. 156)
“we hypothesized that bottom-up triggered shifting of auditory attention caused by LDTs and top-down controlled shifting of auditory attention associated with CASs would activate overlapping brain networks in the parietal and frontal areas.” (Salmi et al., 2009, p. 157)
“Ts became longer (paired samples t-test, t(18) = 2.9, p < 0.01) when a target was preceded by an LDT in the to-be-ignored stream” (Salmi et al., 2009, p. 157)
“RTs to the targets became shorter (t(18) = 6.8, p < 0.0001) when a target was preceded by an LDTs in the same, to-be-attended tone stream (left panel, grey bar). This suggests that bottom-up triggered auditory attention may facilitate performance if the triggering event occurs among to-be-attended sounds.” (Salmi et al., 2009, p. 157)
“bottom-up triggered shifting of attention associated with LDTs and top-down controlled shifting of attention associated with CASs activated overlapping areas in the ventromedial SPL, left IFG/MFG, left FEF/PMC, and right TPJ.” (Salmi et al., 2009, p. 158)
“we found activity also in the lateral and ventromedial OC for top-down controlled attention shifts. This OC activity was probably related to processing of the visual cue.” (Salmi et al., 2009, p. 160)
“these LDTs indeed appeared to suppress subsequent top-down controlled CASs in a bottom-up manner although this suppression was not observable in task performance.” (Salmi et al., 2009, p. 160)
“areas within the suggested ventral (visual) attention system are involved in both bottom-up triggered and top-down controlled attention in audition.” (Salmi et al., 2009, p. 160)
