10 heads of adult cadaver were used for investigation of the motor and sensory area of scalp acupuncture. The results are as follows: both the surface anatomy of precentral and postcentral gyrus were not exactly match with the tnotor and sensory area decribed in acupuncture textbook respectively. They were backward. Among them

the upper points were 0. 5cm backward to motor area and 1.Ocm to sensory area

the lower point of precentral gyrus was 1.0cm posterior to the intersecting point of the eyebrow-occiput line and the anterior border of the natural line of the hair at the temple

while the lower point of postcentral gyrus is 2. 4cm posterior to the intersecting point above described.Therefor

the authors suggested that the motor and seasory area of the scalp acupuncture should be backward and recommended: take the pount 1. 0cm and 3. 0cm posterior to the midpoint of anteroposterior midline as the upper point of motor and sensory area respectively

1. 0cm and 2. 0cm posterior to the intersecting point above described as the lower point respectively. In this way

the motor and sensory areas are better rnatched with precentral and posrcentral gyrus than before (P<0.05).
