Yet, vestibular EPs of brainstem, cerebellar, and cortical origin have been reported as early as the 1960s.  ...  Generators were consistently found in the parieto-insular and temporo-parietal junction—the core of the vestibular cortex—as well as in the prefrontal and frontal areas, superior parietal, and temporal  ...  Magnetic vestibular stimulation can be used as vestibular stimulation in conjunction with resting-state fMRI or fMRI studies of cognitive processes.  ...

Increased recognition of MdD in a persistent pathological form occurred after the publication of a case series of six patients by Brown and Baloh in 1987.  ...  Although several studies have shown that brief periods of MdD are common in healthy individuals, this otherwise natural phenomenon can become persistent in some individuals and lead to severe balance problems  ...  The more commonly used vestibular evoked myogenic potential (VEMP) test, which involves a series of loud clicks to activate an inhibitory saccular-cervical pathway, 32 has been used clinically by many  ...
