11 snips
Mar 24, 2026 Lisa Barrett, psychologist and affective neuroscientist who developed the theory of constructed emotion, and Karen Quigley, psychophysiologist specializing in bodily signaling, explore relational realism, allostasis, and predictive processing. They discuss rethinking emotion universals, how the brain anticipates bodily needs, predictive models of sensation, shifting body-world boundaries, and the relational meaning of neural signals.

Episode notes
Emotions Are Relational Not Hardwired
- Emotions are not fixed circuits but context-dependent relational meanings.
- Lisa Barrett documented 20 years of variability across face, body, and brain showing scowls and heart changes are not reliable emotion markers.
Brain Predicts The Body To Manage Metabolism
- Brains run predictive models of the body to anticipate metabolic needs (allostasis) rather than solely modeling the external world.
- Barrett explains cortical predictions include visceral motor plans that regulate metabolism and generate sensory predictions.
Action Potentials Have Relational Meaning
- Neural spikes have no inherent meaning; their meaning is relational and depends on sender, receiver, and neural context.
- Barrett notes the same spike train can be a motor plan or a sensory prediction depending on connectivity and timing.
