Abstract

âº Anterior insula and posterior insula have different BOLD pattern encoding for pain. âº Pain is coded as higher amplitude of BOLD response in the posterior insula. âº Pain is coded as shortened latency of BOLD response in the anterior insula. âº Pain is characterized by differences in amplitude and latency of the BOLD response.
