Human brains may organize emotions as positions on a hexagonal map, not as isolated labels.

The vmPFC, a brain region tied to emotion and decisions, showed a six-sided signal. Feelings may be coordinates, not labels.

Faces changed. Phrases changed. Yet the ventromedial prefrontal cortex, a brain region involved in emotion and decision-making, traced a sixfold pattern as people moved through pleasantness and arousal. That repeat across faces and words hints that emotional meaning may be organized by relationships, not stored as labels. The map is still under investigation.

• What it could changeA shared emotional map could explain how the brain recognizes new feelings from familiar ones.
• How it touches todayThe same feeling can arrive through a face, a phrase, or a memory, yet still find its place.
• Our futureIf emotion is a map, changing how we read its coordinates could change how we understand ourselves.

• The researchers reported that the vmPFC encoded affective space with robust hexadirectional modulation, consistent with grid-like coding of abstract emotion concepts.pmc
• A 2025 review proposes that emotion concepts and their relations may be learned through reciprocal hippocampal-prefrontal systems involving grid-like coding.doi
• Film-based fMRI research found hippocampal-prefrontal systems represented emotion concepts hierarchically and tracked affective-space locations across multiple temporal scales.nature
