Baltimore Longitudinal Study of Aging (BLSA), 2013–2015.
| Vestibular Testing and Brain Volume | n | Mean (±SD) |
|---|---|---|
| cVEMP amplitude1 in μV | 35 | 1.75 (±0.54) |
| oVEMP amplitude2 in μV | 40 | 19.3 (±9.50) |
| VOR gain | 90 | 0.98 (±0.15) |
| Intracranial volume in mm3 | 103 | 1,235,318 (±118,375) |
| Mean3 hippocampal volume in mm3 | 103 | 3178.9 (±411.6) |

For those who had a response, the cVEMP amplitude of the better ear was used for the analysis.

For those who had a response, the oVEMP amplitude of the better ear was used for the analysis.

The mean of the right and left hippocampal volume for each participant was calculated. The mean of this value for the entire cohort is displayed in the table.
