The Neural Correlates of Chronic Symptoms of Vertigo Proneness in Humans
Fig 1
A whole brain group comparison between patients with chronic vestibular symptoms and healthy subjects.
A comparison of source analyzed resting state brain activity between patients with chronic symptoms of vertigo and healthy subjects revealed: (A) a significant increase (in red) of alpha2 activity in the posterior cingulate cortex extending into the parahippocampal area, precuneus, and cuneus regions, (B) a decrease (in blue) for beta3, activity predominant in the ventral medial prefrontal cortex/pregenual anterior cingulate cortex, subgenual anterior cingulate cortex and the medial orbitofrontal cortex,as well as the left anterior midtemporal area and the dorsal attention network which incorporates regions of the superior parietal area and dorsolateral prefrontal cortex). As for gamma, figure (C) shows decreased (in blue) for gamma frequency band, mostly present in the pre-supplementary motor area extending into the frontal eye fields as well as the precuneus.
