Motivation: Understanding autonomic regulation during a cognitive task is vital for unraveling its neural mechanisms. This study delves into autonomic regression in fMRI, examining the roles of respiration, pupil size, and PPG amplitude during alertness.
Goal(s): Our goal is to enhance our understanding of the autonomic nervous system's response to alert conditions by analyzing fMRI data and modeling with various physiological signals.
Approach: Through the examination of respiration, pupil size, and PPG amplitude and fMRI, we aim to reveal patterns of autonomic regression.
Results: The results uncover significant associations between autonomic parameters and fMRI, shedding light on the neuro-physiological correlates of cognitive stress.
Impact: Our findings advance strategies for managing systemic variations during alert conditions, providing valuable insights for fMRI researchers.
