    Notes: Summary The area of the anterior horn of the right lateral ventricle and five ventricular indices:(1) maximum width of the anterior horns, (2) minimum width of the anterior horns, (3) sum of these maximum and minimum widths, (4) ventricular index, and (5) cella media index were measured from the CT scans of 198 cases considered to be “normal”. The area of the right anterior horn and indices 1–4 were measured on the slice which most clearly showed Monro's foramina and index 5 was measured on the slice 2 cm above. The size of the ventricular system increased steadily with age. The sum of the maximum and minimum widths of the anterior horns was most highly correlated with the area of the right anterior horn. Using this ventricular index, we graded brain “atrophy” in each age group.

    Notes: Abstract Muscle sympathetic nerve activity by (microneurograph) blood pressure and heart rate has been studied in patients with amyotrophic lateral sclerosis and in age-matched normal subjects (controls) at rest and during head-up tilt. Muscle sympathetic nerve activity in amyotrophic lateral sclerosis patients was significantly increased at rest unlike controls. There was no correlation between muscle sympathetic nerve activity and age in the patients with amyotrophic lateral sclerosis. Elevated muscle sympathetic nerve activity was present mainly in younger patients. There were no differences between blood pressure or heart rate in either group at rest or during head-up tilt in amyotrophic lateral sclerosis. The increase in muscle sympathetic nerve activity following tilt in the amyotrophic lateral sclerosis patients was less than in the controls, but they had no postural hypotension. The possible reasons for this observation of increased muscle sympathetic nerve activity at rest in amyotrophic lateral sclerosis are discussed.
