Interoception: the sense that reads your own body
Beyond the classic five senses lies interoception — your perception of your internal state, from heartbeat to hunger. Explore how it works and its surprising links to emotion, anxiety, and the way we make decisions.
Listen in the Fylom app.
Eighty percent of vagus nerve fibers send signals from the body to the brain, not the reverse.
Three-bladed propeller proteins called PIEZO translate physical pressure from organs into electrical brain signals.
The insula serves as the primary hub where the brain processes internal physiological data.
Reframing physical stress symptoms as preparation for a challenge can alter the body's hormonal response.
Anxiety disorders often cause the brain to interpret benign internal signals as immediate physical threats.
Current vagus nerve stimulation treatments lack precision by affecting multiple internal organs at the same time.

Fylom generates episodes like this on any topic you're curious about.
Fylom episodes are researched, written, and voiced by AI. Automated checks help catch inaccuracies, but episodes aren't reviewed by a human and AI can still get things wrong. Treat them as a starting point, not a source of record — more in our accuracy disclaimer.
