# Second brain

**Type:** Idea

**As of November 2026, Second brain has been mentioned in one podcast episode on Ryan Hawk (Nov 2026).** Tiago Forte recommended it: It's an external system... where you offload and you externalize your memory, your ideas, your insights.

The enteric nervous system (ENS) is one of the three divisions of the autonomic nervous system (ANS), the others being the sympathetic nervous system (SNS) and parasympathetic nervous system (PSNS). The ENS is formed from the myenteric plexus, and the submucosal plexus, and consists of a mesh-like system of neurons that governs the functions of the gastrointestinal tract, including motility and secretion, and is often referred to as the "second brain". It is derived from neural crest cells.
