“Pain Affect without Pain Sensation in a Patient With a Postcentral Lesion”, M. Ploner, H.-J. Freund, A. Schnitzler1999-05 (, ; backlinks)⁠:

We report findings from clinical examination and cutaneous laser stimulation in a 57-year-old male, who suffered from a right-sided postcentral stroke.

In this patient, we were able to demonstrate:

  1. a dissociation of discriminative and affective components of pain perception and, for the first time in humans, (2) the dependence of sensory-discriminative pain component and first pain sensation on the integrity of the lateral pain system.
