In this study an attempt was made to find out whether there is a relationship between the electrical potentials from the left motor area of the brain and the tremor of the third finger of the right hand. Some records also were taken from the visual area and from the index finger. The brain wave and the tremor were recorded simultaneously on sensitized paper.
