2. Research Seminar
Reconceptualizing the affective processes in the brain – Insights from meta-analytic modeling of neuroimaging data
Speaker: Dr. Kenneth YUEN, Neuroimaging Center, Johannes Gutenberg University Mainz
Date: 27 Mar 2019 (Wed)
Time: 11:00 am – 12:00 pm
Venue: Room 201, Ho Tim Building, CUHK
Abstract
How affective experiences arise in the brain remains a heated topic of debate – whether a set of distinctive basic emotions exist, each associated with a unique neural fingerprint, or whether different emotions should be viewed as interactions between two or three orthogonal dimensions, each characterized by a corresponding brain circuit.
In an attempt to investigate the issue, this study analyzed a large body of emotion-related data from 1297 published neuroimaging studies to identify neural circuits and activities associated with discrete emotional states. The study identified two brain circuits that closely resemble the brain networks of: i) hedonic value representation and saliency processing, and ii) affective appraisal and self-referential processing. The findings call for an evolutionary-based framework of understanding affective processes in the brain. Further implications on mental health and resilience will be discussed.
1. PhD Annual Seminar
Emotion dysregulation and the stress response systems
Speaker: Mr. Isaac IP, PhD student
Date: 25 Jan 2019 (Fri)
Time: 5:00 – 6:30 pm
Venue: Room 213, Ho Tim Building, CUHK
Abstract
Emotion dysregulation may be thought as a form of maladaptive responses to stress. These responses have a strong physiological component that is controlled by the stress response systems. This presentation will introduce two major psychophysiological theories that attempt to explain emotion dysregulation by the functioning of the stress response systems. It will discuss the strengths and weaknesses of the theories and propose an approach to better investigate the relationship between the stress response systems and emotion dysregulation. Specific research questions and their implications for our understanding of the nature of emotion dysregulation will be discussed.
