Real-time fMRI for Insular Cortex Brain State-triggered Experience Sampling
Drexel University
Summary
In a neuroimaging session, study participants will repeatedly and intermittently report the content of their ongoing, self-generated experiences based on an experience-sampling protocol in which self-report ratings will be triggered based on real-time analysis of the participant's current brain state. The protocol will be conducted while participants are undergoing MRI scanning.
Description
The investigators will develop a new approach called real-time functional MRI (fMRI)-triggered experience-sampling to efficiently sample spontaneous neural events (of a predefined type) and to map those events to specific qualities of self-generated experiences. Within 60 healthy adults, the investigators will use online (real-time) fMRI analysis to detect brain activations and trigger the appearance of visual rating scales so that participants can report their experiences immediately after the occurrence of a neural event of interest. The investigators will develop and validate the approach w…
