In this episode we discuss the relationship between interoceptive processing, conscious and subconscious as well as how that relates to the polyvagal theory. We explore how interoception changes in the different states of the nervous system, such as ventral vagal, sympathetic, and dorsal vagal states. We also discuss the role of interoception in emotions and feelings, and how it can impact social interactions. Our conversation begins our discussion around the importance of understanding interoceptive processing in clinical practice and hopefully offers insights into how we can support individuals with different interoceptive needs.

Key Takeaways:

• Interoception involves the processing of internal bodily sensations and emotions.
• Interoceptive processing is influenced by the state of the nervous system, such as the ventral vagal state, sympathetic state, and dorsal vagal state.
• The quality and function of interoceptive receptors can change depending on the state of the nervous system.
• Interoceptive cues can signal safety or threat, leading to different physiological and emotional responses.
• Attentional processes play a role in interoceptive processing, with the ability to shift attention between internal and external cues.

Our Favourite Quote from this episode:

"The valence-based function of interoception tells us if something is good or bad, and if we want more or less of it." – Tracy M Stackhouse.
