Hypothalamic activation discriminates painful and non-painful initiation of the trigeminal autonomic reflex – an fMRI study.
Abstract
The role of the trigeminal autonomic reflex in headache syndromes, such as cluster headache, is undisputed but sparsely investigated. The aim of the present study was therefore, to identify neural correlates that play a role in the initiation of the trigeminal autonomic reflex. We further aimed to discriminate between components of the reflex that are involved in nociceptive compared to non-nociceptive processing.
