abstract = {The right inferior frontal cortex (rIFC) is frequently
activated during executive control tasks. Whereas the
function of the dorsal portion of rIFC, more precisely the
inferior frontal junction (rIFJ), is convergingly assigned
to the attention system, the functional key role of the
ventral portion, i.e., the inferior frontal gyrus (rIFG), is
hitherto controversially debated. Here, we used a two-step
methodical approach to clarify the differential function of
rIFJ and rIFG. First, we used event-related functional
magnetic resonance imaging (fMRI) during a modified stop
signal task with an attentional capture condition (acSST) to
delineate attentional from inhibitory motor processes (step
1). Then, we applied coordinate-based meta-analytic
connectivity modeling (MACM) to assess functional
connectivity profiles of rIFJ and rIFG across various
paradigm classes (step 2). As hypothesized, rIFJ activity
was associated with the detection of salient stimuli, and
was functionally connected to areas of the ventral and
dorsal attention network. RIFG was activated during
successful response inhibition even when controlling for
attentional capture and revealed the highest functional
connectivity with core motor areas. Thereby, rIFJ and rIFG
delineated largely independent brain networks for attention
and motor control. MACM results attributed a more specific
attentional function to rIFJ, suggesting an integrative role
between stimulus-driven ventral and goal-directed dorsal
attention processes. In contrast, rIFG was disclosed as a
region of the motor control but not attention system, being
essential for response inhibition. The current study
provides decisive evidence regarding a more precise
functional characterization of rIFC subregions in attention
and inhibition.},
