Anatomical location

• one could think that PGi could be part of the auditory where stream due to its location in the parietal lobe posterior to A4 and STV, but Rolls (2022) - NeuroImage, Rolls et al. (2023) - Cerebral Cortex clearly shows more connectivity with semantic areas usually assigned to the Auditory What-Stream (Ventral).

Function(s)

semantic language

• language-related semantic functions (Rolls et al. (2023) - Cerebral Cortex)

Connectivity

• effective connectivity with STS (Rolls et al. (2023) - Cerebral Cortex)
• along with TPOJ1, STV, PSL, TGv, TGd, PGi (Rolls et al. (2023) - Cerebral Cortex)
• part of the Auditory What-Stream (Ventral) (Rolls et al. (2023) - Cerebral Cortex)
• from PGi connections to STSvp, STSva, and TE1 to TGd (Rolls (2022) - NeuroImage)

Projections

• part of the language-related semantic system (Rolls et al. (2023) - Cerebral Cortex)

PFC targets

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