Affect before diagnosis: applying affective neuroscience to psychiatry

Jaak Panksepp spent nearly five decades mapping the primary-process affective systems of the mammalian brain across different species, producing a framework of considerable empirical power that is functionally invisible within psychiatry. Psychiatry has not built upon that literature in human contexts. Consequently, Affect has never occupied the foundational place in psychiatry that the evidence warrants. This paper attempts to close that gap and assembles twelve converging lines of evidence for subcortical primacy of Affect, including evidence not previously synthesized for this purpose: pseudobulbar affect, gelastic and dacrystic epilepsy, double dissociation of volitional and emotional facial expression, affective blindsight, and neonatal emotional behavior. The evidence shows that Affect is generated subcortically, the cortex modulates rather than creates it, and when cortical regulation is removed or impaired, affective states persist or intensify. From this evidence, personality is best understood as an individual’s position in a configuration space defined by subcortical Affect generation parameters and cortical regulatory capacity, with psychopathology occurring when signal
