Definition

A somatic map is an organized neural representation of the body’s ongoing condition, including visceral, chemical, muscular and skin-related signals. RB2’s Damasio discussion assigns primary visceral mapping to subcortical structures and a secondary interoceptive role to insular and somatosensory cortex. The map is selective and participates in regulation; the later account rejects a detached self reading it as an internal spectator.

Explanation

The direct anatomical discussion describes an updating portrait rather than a literal exhaustive copy. Visceral representations include brainstem nuclei, notably the nucleus of the solitary tract, alongside peripheral and other subcortical mapping. The cortical regions mentioned in the source are not silently promoted to the sole origin of bodily feeling.

The earlier formulation describes the brain interpreting maps within a self-context. RB2 explicitly revises this with the later hypothesis of hybrid neural and non-neural physiology and reciprocal exchange. The self is partly constituted through feeling rather than installed as an already complete reader behind the representation.

The omission check adds that interoception filters bodily details for salience: a map is neither evenly precise nor a full readout of every heartbeat and tissue. AB’s native discussion also preserves the two-way account. The proposed entry keeps representation, regulation and felt experience related without declaring every mapped signal consciously felt.
