IFJ (Inferior Frontal Junction)
Stream: ventral what safe
Classical equivalent: L: Precentral Gyrus, R: Pars Opercularis, L/R: 6r, BA6 + BA8 + BA44, 44 (Bedini & Baldauf (2021))
Mapped to Glasser: Inferior Frontal Junction
MNI Coordinates
- Right: [46 12 28] (Bedini (2023) - Brain Structure), [44.96±2.55 8.94±5.92 27.21±3.63] (Bedini & Baldauf (2021))
- Left: [−42 6 30] (Bedini (2023) - Brain Structure), [-43.78±4.88 7.80±3.18 28.30±5.59] (Bedini & Baldauf (2021))
Anatomical location
- BA6, BA8, BA44, 44 (Bedini & Baldauf (2021))
- The IFJ is localized dorsal to the junction of the iPCS with the IFS. (Bedini & Baldauf (2021))
- lesser extend BA9/46v (Bedini & Baldauf (2021))
Function(s)
- procesing non-spatial information, working memory, object based (Bedini & Baldauf (2021)) (Bedini (n.d.))
- sensitivity to the stimulus context and sensory domain (Bedini & Baldauf (2021))
- maintenance of goal-related information to control movement in a domain-specific way (Bedini & Baldauf (2021))
- involved in top-down attention and show evidence of sustained activity in response to a cue (Bedini & Baldauf (2021))
- more context dependent than FEF and influenced by bottom-up factors (Bedini & Baldauf (2021))
- could modulate DAN activity according to the current task demands and of toggling between DAN and VAN activities. (Bedini & Baldauf (2021))
Connectivity
- the bilateral IFJ was always coactivated,
- no FEF coactivations in the IFJ MACM results, except for the ipsilateral FEF in the LH IFJ MACM analysis. (Bedini (2023) - Brain Structure)
- reached by terminations of the SLF2 and SLF3 (Bedini & Baldauf (2021))
- part of the FPN and language network (Bedini & Baldauf (2021))
- left IFJ involed
- part of the multipledemand system, particularly the IFJp, IFJa and FEF partially (Bedini & Baldauf (2021))
IFJa
- partial multiple-demand characteristics (Bedini & Baldauf (2021))
IFJp
- part of the multipledemand system, particularly the IFJp, IFJa and FEF partially (area i6-8) (Bedini & Baldauf (2021))
- activated in relational reasoning and math task contrasts
