The purpose of this study was to compare the effectiveness of both high volt galvanic current (HVG) and isometric exercise to strengthen the quadriceps femoris muscles in 17 healthy subjects. The subjects were divided into three groups. The Control Group (n = 6) received no exercise or stimulation. The Isometric Exercise Group (n = 5) performed 15 sessions of maximum isometric contractions, and...

The human vestibular cortex has mostly been approached using functional magnetic resonance imaging and positron emission tomography combined with artificial stimulation of the receptors or nerve. Few studies have used electroencephalography benefited from its high temporal resolution to describe spatiotemporal dynamics information processing first milliseconds following stimulation. Evoked pote...

For decades it has been speculated that there is a close association between the vestibular system and spatial memories constructed by areas of the brain such as the hippocampus. While many animal studies have been conducted which support this relationship, only in the last 10 years have detailed quantitative studies been carried out in patients with vestibular disorders. The majority of these ...

23 Irregular vestibular afferents exhibit significant phase leads with respect to angular velocity of 24 the head in space. This characteristic and their connectivity with vestibulospinal neurons 25 suggest a functionally important role for these afferents in producing the vestibulo-collic 26 reflex (VCR). A goal of these experiments was to test this hypothesis using weak galvanic 27 stimulatio...

Cathodal galvanic currents activate primary vestibular afferents, whereas anodal currents inhibit them. Pulsed galvanic vestibular stimulation (GVS) was used to determine the latency and initiation of the human vestibuloocular reflex. Three-dimensional galvanic vestibuloocular reflex (g-VOR) was recorded with binocular dual-search coils in response to a bilateral bipolar 100-ms rectangular puls...
