皮膚刺戟の眼振及び全身性振盪に及ぼす影響

Effects of touch and pressure on the skin upon the eye-, limb-, and general-nystagmus.

　私共はさきに^1）眼振に對する皮膚壓迫の成績について本誌上に述べたが，その後更にその成績について詳細なる追加實驗を行つたところ以下述べるような興味ある事實の發展をみたのでこゝに報告する。

　We reported previously (1952) that the stimulus such as touch to the skin acts facilitatory to the eye-nystagmus, on the contrary prrssure on the skin acts inhibitory.

　In later experiments, the following was found;

1) Pressure on the skin or clipping of the earlobe's root results in decreasing or diminishing the spikes of the eye-muscles in the rapid phase and in slight increasing that in the slow phase.

2) Similar stimulus on the skin inhibits the limbnystagmus completely, which is shown as the spikes synchronous with the rapid phase of the eye-nystagmus.

3) Touch of the skin evokes the reversal effects on the eye- and limbnystagmus.

4) Such difference of reactivity to touch or pressure stimulus between the rapid and slow component of the nystagmus suggest the fundamental specificity or different property of the two.
