MNI Coodinates

• Right:
• Left:
  (Bezeichnung vor Glasser: aSTG) MNI: [-56 11 -10] (Frühholz (2015) - NeuroImage)

Anatomical location

• on PPo and STG anterior to Herschl’s Gyrus (also TA2) (Ahveninen et al. (2006) - PNAS)
• part of the STG
• proposed to be part of a superior (i.e. anatomically dorsal) bank of the STS cortex

Function(s)

• part of the Auditory What-Stream (Ventral) (Ahveninen et al. (2006) - PNAS)
• more activated in LANGUAGE STORY-MATH and TOM-RANDOM compared to TA2 (Glasser et al. (2016) - Nature)
• realtive to TGd is more activated in STORY and CUE-AVG (Glasser et al. (2016) - Nature)

left STGa

• showed a general main effect for the explicit compared with the implicit task, and thus might reflect a rather general evaluation of voices independent of the emotion (Frühholz (2015) - NeuroImage)

Connectivity

• to IFG via strong Auditory What-Stream (Ventral) consisting of the inferior longitudinal fasciculus (ILF) and the inferior fronto-occipital fasciculus (IFOF) in its posterior portion, and the extreme capsule (EmC) in the anterior portion (Frühholz (2015) - NeuroImage)
• to IFG also via Auditory Where-Stream (Dorsal), but higher pathway probability via ventral compared to dorsal (Frühholz (2015) - NeuroImage)
• to left fOP by Auditory Where-Stream (Dorsal)

Projections

PFC targets

• connects to part of Broca’s Area BA45, 45 (Rolls et al. (2023) - Cerebral Cortex)
