Summary

Estonian-American neuroscientist who founded affective neuroscience, identifying seven primary emotional systems in the mammalian brain (SEEKING, RAGE, FEAR, LUST, CARE, PANIC/GRIEF, PLAY) through cross-species neurological research.

Core Contribution

Demonstrated that the mammalian brain contains genetically encoded primary emotional systems shared across species — discovering the SEEKING system as the primary appetitive motivational circuit — providing the neurological foundation for a biological theory of emotion and meaning.

Key Spikes & Highlights

  • SEEKING as the Master Emotion (identified a brain circuit — the mesolimbic dopamine system — that is not pleasure per se but the anticipation of reward, the fundamental motivational system underlying all goal-directed behavior, making desire more primary than satisfaction)
