CBB talk series
The Cognitive Brown Bag (CBB) is a graduate student organized talk series, primarily attended by the faculty, graduate students, and staff from the cognitive labs at Dartmouth College. A list of past CBB talks can be found here.
The 2023-2024 talk series is organized by Yong Hoon Chung (Stoermer Lab), Clara Sava-Segal (Finn Lab), and Jae Hyung Woo (Soltani Lab).

| Mijin Kwon (Dartmouth College) | Domain-general and selective representations of pain, appetitive processes, aversive processes, and cognitive control in the insula | The insular cortex has been hypothesized as an integrative hub while also containing specialized areas, such as the pain-processing posterior zone exhibiting significant functional specificity. This study investigates functional integration and modular specialization in the human insular cortex using multi-study fMRI data (N = 540 participant-level maps; 36 studies) across four functional domains: pain, appetitive processes, aversive processes, and cognitive control. We address two key questions: 1) Are there discrete functionally selective zones alongside a domain-general hub? 2) What microscale and macroscale functional anatomical features enable this complex organization? Our findings reveal domain-selective zones for pain (mid-posterior), appetitive processes (mid), aversive processes (ventral anterior), and cognitive control (dorsal anterior/mid insula), as well as a domain-general hub in the dorsal anterior insula. These zones exhibit distinct patterns in coactivation with other brain regions, functional decoding, cytoarchitectonic mapping, and neurotransmitter receptor density profiles. During the presentation, I will discuss these results and seek feedback for the current manuscript revision. |
