Stream: where dorsal
Classical equivalent: IPL
Mapped to Glasser: BA39/BA40: PGi, PSL, STV → BA40 //
TPOJ1, TPOJ2 → BA39

Anatomical location
- BA39/40 particularly the angular and supramarginal gyri (Rauschecker & Scott (2009) - Nature Neuroscience)
Function(s)
-
linguistic functions (Rauschecker & Scott (2009) - Nature Neuroscience)
-
part of the pholological loop (Rauschecker & Scott (2009) - Nature Neuroscience)
-
working memory (Rauschecker & Scott (2009) - Nature Neuroscience)
-
the angular gyrus is recurited higher-order linguistic factors improve speech comprehension (Rauschecker & Scott (2009) - Nature Neuroscience)
-
The IPL could provide an ideal interface, where feed-forward signals from motor preparatory networks in the inferior frontal cortex and premotor cortex (PMC) can be matched with feedback signals from sensory areas (Rauschecker & Scott (2009) - Nature Neuroscience)
-
A meta-analysis of altogether human imaging studies provided evidence that the vast majority of auditory spatial studies involved activation of the postero-dorsal pathway (pST, IPL, and SFS), whereas only two activated antero-ventral areas (aST, IFC) (siehe pSTG) (Rauschecker & Scott (2009) - Nature Neuroscience)
not:
- not driven my acoustic processing of speech (Rauschecker & Scott (2009) - Nature Neuroscience)
Connectivity
- from BA44, 44 to IPL (Rauschecker & Scott (2009) - Nature Neuroscience)
Projections
- feedback signals from pSTG (could be afference copies) (Rauschecker & Scott (2009) - Nature Neuroscience)
- ist pST → pSTG ?
