title: [The surface anatomic observation of cerebral porecentral and postcentral gyrus for scalp acupuncture].
abstract: 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 motor and sensory area described in acupuncture textbook respectively. They were backward. Among them, the upper points were 0.5cm backward to motor area and 1.0cm 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. Therefore, the authors suggested that the motor and sensory area of the scalp acupuncture should be backward and recommended: take the point 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 matched with precentral and posrcentral gyrus than before (P < 0.05).
