The noteworthy circadian rhythmicity of cluster headache has led to the concept of a central origin for its initiation [65 67].
Overall, our data suggest that certain types of OP, at least those of a central origin, and bruxism are caused by a disruption and homeostatic imbalance of cerebral neurobiochemistry, particularly of the excitatory and inhibitory neurotransmitters in the trigeminal nervous system.
Others think that many societies in the area deserve credit, arguing that regional differences in Olmec ceramics, for example, show that the style was not of a central origin.
Dizziness from a central origin is often associated with descriptions of disequilibrium, motion sensitivity, and nausea and is often triggered by sensory processing of mismatched afferent inputs during movement (Herdman and Clendaniel 2014).
Exclusion criteria were a primary cardiac or central origin of respiratory failure, and overt sepsis at the time of admission.
The FCL attachment point was anatomically located, and a guidewire was introduced just anteriorly to the central origin of the FCL.
"This conflict between peripheral and central origin of tinnitus is simplistic," he said.
These results could not reduce the validity of the theory about the central origin of pain in tension-type headache [32], rather they would indicate that low serum NAA is not related to central mechanisms of pain processing, but to neuronal abnormalities which may specifically predispose to migraine.
In follow-up experiments an anesthetic block of the peripheral nerves proximal to the stimulation site prevented the afferent flow to the central nervous system, confirming the central origin of the enhanced mechanical output produced by the wider pulse-width paradigm (Collins 2007).
Small tumors are more commonly associated with vertigo of peripheral origin because of missing deafferentation [ 74, 75], whereas large tumors, especially those that are slow-growing, will cause compression of the cerebellum or brainstem [ 74] and therefore central origin of vertigo.
