πŸ“ Cortisol Rapidly Affects Amplitudes Of Heartbeat-Evoked Brain Potentials – Implications For The Contribution Of Stress To An Altered Perception Of Physical Sensations?

Interoception, the perception of bodily processes, plays an important role in the subjective experience of emotions (Wiens, 2005), in consciousness (Damasio, 2003), and in somatic symptom generation (Eley et al., 2004). Stress affects interoception in that activation of the autonomic nervous system, as one of two major physiological stress systems (Chrousos and Gold, 1992), mobilizes the cardiovascular system and may therefore enhance cardioceptive neural traffic (Eichler and Katkin, 1994; Schandry et al., 1993; Schulz et al., 2013; Schulz et al., 2011). Little is known, however, about the impact of HPA stress axis activation (the second physiological stress system) on the processing of visceral-afferent signals.
