  • Abstract
  • Look Inside

The Minor Tremor (MT) and EEG were investigated by automatic frequency analyser, and the relation between the frequency spec-tra of MT and EEG were studied in normal subjects.

The subjects were divided into 3 groups, namely age of puberty (2nd class students of middle school), young adult (20~29 years) and elderly group (over 60 years old).

I. Frequency distribution of MT

1) The appearance of band α (8~12.5c/s) was most frequent in all subjects.

2) It was found that α3 (11~12.5c/s) ap-peared most frequently in students, α2 (9.5~11c/s) appeared most frequently in young adults and seniles, and that in seniles, the α1, (8~9.5c/s) appearance was resembling the α2 appearance. It seems that elderly subjects show a slower rhythm of MT.

3) The α dominant type was seen most often in all groups and the other types (i. e. θ dominant type or β dominant type) were less in young adults than in students and seniles.

4) Percentage of β>θ type was 72.2% in students, 53.2% in young adults and 52.4% in the senile group.

II. Relation between frequency distribution of EEG and MT.

The frequency spectra of MT were not directly related to those of EEG.
