Connectivity patterns associated with pain phenotypes and severity.

Pain Phenotype and Severity	Connectivity Pattern Alterations
↑ Neuropathic pain intensity	↓ Intralimbic and limbostriatal
↑ Nociceptive pain intensity	↓ Thalamocortical and Thalamolimbic
↑ Neuropathic + nociceptive pain intensities	↑ and ↓ Limbocortical (↓ pPaHC – parietal; ↑ amygdala - parietal)
Neuropathic > nociceptive pain intensity	↓ Limbocortical
Neuropathic < nociceptive pain intensity	↑ Limbocortical

Summary of connectivity pattern alterations associated with pain phenotypes and severity. Full results and specific regions can be found in Table 3. Posterior parahippocampal gyrus (pPaHC).
