What is the nature of autonomic signals and how do they shape introception? This study presents a new method for evaluating cardiac interoceptive ability, measuring sensitivity to naturalistic changes in the number of heartbeats over time periods. The results of this research show participants have an overall tendency towards sensing fewer heartbeats during higher heart rates. This likely reflects...

Most of us have heard about the Flight and Fight response and the activation of the sympathetic system. But, what is often overlooked is the sheer complexity of sympathetic activation as it differentially and specifically modulates different organ systems. Different stressors activate and inhibit specific target organs, including specific muscle groups. Understanding the mechanisms how the central...
