In meiner Bachelorarbeit werde ich sehr tief in Neuroscience und Brain Connectivity eindringen.
Es geht darum, den What- und Where-Pathway des Auditory Cortex zu verstehen und die Verbindungen zum Prefrontal Cortex zu überprüfen. Dafür brauche ich eine These.
Welche ROIs kommen für die Verbindung zum PFC in Frage?
Wie werden auditive Reize im Gehirn verarbeitet?
Dafür müssen wir uns die Anatomie des Auditory Cortex anschauen. Hier gehen wir voll ins Detail!
Wir fangen im Kern an. Der A1 ist der kern des Auditory Cortex.
→ strongest connection to MBelt and LBelt regions, followed by PBelt ad RI
A1 → A4 and TA2 was weaker.
Im A1 werden die grundlegenden Reize verarbeitet - wie im V1 für Vision
Um den A1 herum bildet sich der Belt. In dem
Ich brauche eine Liste von allen Regionen
| Region | Function | from Conenctivity | to connectivity | location | additional info |
|---|---|---|---|---|---|
| A1 | from V1-V3 (but not reverse) and from OP2-OP3 (somatosensory) | ||||
| LBelt | A1, PBelt (strong) / MBelt, RI, A4 (moderate) / from V1/V2 | A1, PBelt / A5 and TA2 | weak with somatosensory | ||
| MBelt | A1, PBelt (reciprocal) / LBlet & 52 (moderate) | A1, PBelt / A4 and TA2 (more than vice versa) | no. connectivity from V1-V3, little somatosensory | ||
| 52 | transitional region | form MGN | MBelt, A1, LBelt, PBelt, PF, A4 (more than reverse in this order) / somatosensory regions | not known in macq / might be a MBelt area | |
| PBelt | LBelt, MBelt (rec., strong) / A1, RI, 52 (moderate) | LBelt, MBelt (strong) / A1, RI (moderate) | weak with visual and somatosensory / subdiv. into RPB and CPB | ||
| PFcm (im IPL) | 52, PFop (moderate), 7AL | RI | part of the inferior parietal cortex somatosensory processing hierarchy | extensice conn. with somatosensory (5mv, FOP1-FOP3, OP1, Pol1-Pol2) | |
| RI (Retroinsular Region) | moderate: A1, 52, LBelt, MBelt, PBelt / /somatosensory: 3a, 3b, 5m and OP1-OP4 (idont know which direction) | A1, 52, LBelt, MBelt, PBelt, to A4, A5, TA2 | |||
| A4 | strong:PBelt, moderate: MBelt, LBelt, less: A1 | ||||

LBelt and MBelt:
- LBelt and MBelt each consist of 3 subdivisions (AL, ML, and CL for LBelt; AM, MM, and CM for the MBelt)
General Info
- somatosensory information is used in audiomotor learning for speech (Ohashi and Ostry 2021)
- Ventral Intraparietal Region (VIP) in the intraparietal sulcus (IPS) has been shown to receive anatomical input from auditory-related regions
