0.1 Outline Bachelorarbeit
- Abstract
Outline 1.0 Introduction

- 1.1.1 classic visual model (two streams hypothesis)
- 1.1.2 state of the art in the auditory cortex (teaser for the theoretical part)
- 1.1.3 Introduction to dual stream processing

- 1.2 The Gap, Top-Down Control of Auditory Streams
- we know that those paths exist, but who controls them?
- Introduction Top-Down Attention
- comaprison to Bedini & Baldauf (2021)
- Ziel: Zeigen, wo die Forschungslücke liegt, gilt diese Aufteilung auch für das Hören?
- 1.3 Hypothesis, A supramodal organization
- prefrontal organization is supramodal
- FEF controls auditory dorsal stream
- IFJ controls auditory ventral stream
- 1.1. From Wernicke’s to Dual Stream

Outline 5.0 Discussion
Link zum Original
- 5.1 confirmation of the supramodal oganization
- summarization of FEF/IFJ connectivity as in Bedini & Baldauf (2021)
- the brain uses “general purpose” attention hubs in the prefrontal cortex
- 5.1.1 Top-Down control architecture
- FEF connection to auditory motion
- FEF connection to speech motor
- maybe subclusturs within FEF and IFJ?
- 5.2 Re-evaluating the auditory where stream
- 5.2.1 The spatial Link
- FEF connection to A4, MT, MST
- mit Rauschecker & Scott (2009) - Nature Neuroscience diskutieren, zeigt dass es räumlich ist
- 5.2.2 The motor link
- FEF controls motor actions
- connections to BA44?
- diskutiere Hickok & Poeppel (2004) - Cognition
- 5.3 Re-evaluating the auditory what stream
- IFJ semantics
- discussing Rolls et al. (2023) - Cerebral Cortex and the groups mentioned
- IFJ vs 44, 45, 47l
- vielleicht bezogen auf Bedini & Baldauf (2021) als ein multiple demand system
- 5.4 anatomical Ambiguities
- A5
- PSL
- STSdp
- 5.5 Predictive Modelling
- aus Glasser et al. (2016) - Nature SUPPL die offline Tasks LANGUAGE-STORY anschauen und scores vergleichen

- bestätigung von Hickok & Poeppel 2007 - Nature
- right hemisphere
- bestätigung von Frühholz (2015) - NeuroImage und Griffiths et al. (1998)
- 5.7 Limitations and Future directions
- resting state fMRI ist indirekt
- glasser atlas ist top, aber manche areale könnte man weiter unterteilen wie A4, A5
- Effective Connectivity nutzen, um die richtung Top-down zu beweisen
- MEG nutzen, um die Frequenzen zu sehen De Vries et al. (2021) - Journal of Neuroscience
