Abstract
Functional near-infrared spectroscopy (fNIRS) provides a non-invasive approach to investigate autonomic responses to various types of stimuli. The aim of this thesis is to use fNIRS to evaluate the hemodynamic and physiological changes in response to aversive and positive visual stimuli. The study suggests that aversive vs. positive stimuli share a neural network composed of frontopolar cortex, prefrontal cortex (PFC), primary and secondary somatosensory areas, and visual cortex. Physiological measure markers such as heart rate variability (HRV), respiration, partial pressure of oxygen are expected to yield differential outcomes in provide differential results in response to negative and positive visual stimuli.
