Spatial summation of pain is associated with pain expectations: Results from a home-based paradigm

This study reproduces spatial summation of pain using home-based procedures and finds a link between pain expectations and spatial summation.

Spatial summation of pain increases logarithmically

This study shows that pain increases logarithmically with stimulus area or separation, not linearly, and that pain intensity and number of stimulation sites affect this relationship.
