Neurofeedback Training of Anterior Insula Activity Based on Unidimensional vs. Multidimensional Interoceptive Regulation Strategies
Sponsor: University of Electronic Science and Technology of China
Summary
The purpose of this study is to compare the neural and behavioral effects of real-time functional magnetic resonance imaging (fMRI) neurofeedback training using two different interoceptive strategies: a unidimensional heartbeat detection strategy and a multidimensional interoception strategy. Specifically, the study compares the efficacy of these two regulation strategies in regulating activity of the anterior insula, a key brain region involved in interoceptive and emotional processing.

real-time fMRI neurofeedback training
Real-time neurofeedback information is computed using the Turbo Brain voyager (TBV) 4.0 software (Brain Innovation, Maastricht, The Netherlands). Functional images are collected and processed in real time based on contrasts of regulation vs. rest conditions. The blood oxygen level dependent (BOLD) signal of the target region is then transformed into visual bars and displayed to participants via the projector screen. Both groups will undergo the same paradigm, but with different interoception strategies.
