Background And Purpose:
A sensitive and frequent clinical sign of a vestibular tone imbalance is the tilt of the perceived subjective visual vertical (SVV). There are no data yet focusing on lesion location at the cortical level as a factor for predicting compensation from the tilt of the SVV.
Methods:
With modern voxelwise lesion behavior mapping analysis, the present study determines whether lesion location in 23 right-hemispheric cortical stroke patients with an otolith dysfunction could predict the compensation of a vestibular tone imbalance in the chronic stage.
Results:
Our statistical anatomical lesion analysis revealed that lesions of the posterior insular cortex are involved in vestibular otolith compensation.
Conclusion:
The insular cortex appears to be a critical anatomical region for predicting a tilt of the SVV as a chronic disorder in stroke patients.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
