Two standard lines must be decided first for dividing the stimulating zones (see Fig. 113).
Anterior-posterior midline: It refers to the line from the midpoint between the eyebrows (the anterior point of the midline) to the inferior border of the external occipital protuberance (the posterior point of the midline).
Brow-occipital line：It refers to the cephalic lateral side line from the midpoint of the superior border of eye-brow to the tip of the external occipital protuberance.
(1) Motor Zone:Location:
The superior point is located 0.5 cm posterior to the midpoint of the anterior-posterior midline, the inferior point at the junction of the brow-occipital line and the anterior border of temporal hairline. The line connecting the two points is the motor zone. The line is divided into five equal parts, the upper 1/5 is the motor zone of the lower limbs and trunk; the middle 2/5 is the motor zone of the upper limbs；the lower 2/5 is the motor zone of the, face, also called the first lingual zone (see Fig. 114).
Indications: The upper 1/5 is for the treatment of contralateral paralysis of the lower limb; the middle 2/5 is for the treatment of contralateral superior paraplegia of the upper limb; the lower 2/5 is for the treatment of contralateral central facial paralysis, aphemia, drooling and dysphonia.
(2) Sensory Zone:
Location: It refers to the horizontal line 1.5 cm posterior to the motor zone. It is divided into five equal parts: the upper 1/5 is the sensory zone of the lower limbs, head and trunk; the middle 2/5 is the sensory zone of the upper limbs; the lower 2/5 is the sensory zone of the face (see Fig. 115).
Indications: the upper 1/5 for contralateral lumbocrural pain, numbness, paresthesia, occiput pain, neck pain, vertigo, tinnitus; the middle 2/5 for contralateral upper limb pain, numbness, paresthesia; the low 2/5 for contralateral facial numbness, migraine, temporomandi-bular arthritis.
(3) Control Zone of Chorea and Tremor:
Location: It refers to the horizontal line 1.5 cm anterior to the motor zone (see Fig. 115).
Indications: Chorea, paralysis agitans.
(4) Vertigo-Auditory Zone:
Location: It refers to the horizontal line 1.5 cm directly from above the tip of the ear, stretching 2 cm to the face and occiput respectively (see Fig. 115).
Indications: Vertigo, tinnitus, hypoacusis.
(5) The Second Lingual Zone:
Location: It refers to the straight line 2 cm posteroinferior to the parietal tubercule and parallel to the anteroposterior midline, stretching 3 cm straightly and downwards (see Fig. 115).
Indications: Anemic aphasia.
(6) The Third Lingual Zone:
Location: It refers to the horizontal line 4 cm stretching backward from the midpoint of the fainting and hearing zone (see Fig. 115).
Indications: Sensory aphasia.
(7) Applying Zone:
Location: It refers to three lines from the parietal tubercule downward. The middle line is straight and the angle of the bilateral lines from the straight line is 40° respectively. All the three lines are 3 cm in length (see Fig. 115).
Indications: Apraxia.
(8) The Zone of Pedal Movement and Sensation:
Location: It refers to two straight lines 3 cm stretching back 1 cm from both sides of the midpoint of the anteroposterior median line and parallel to the midline (see Fig. 116). Indication: Paralysis, pain and numbness of the contralateral lower limb, acute lumbar sprain, nocturia, cortical diuresis and hysteroptosis.
(9) Visual Zone:
Location: It refers to a straight line 4 cm stretching upwards 1 cm from both sides of the posterior point of the anteroposterior midline and parallel to the midline (see Fig. 117).  
Indications: Cortical visual disturbance.
(10) Balance Zone:
Location: It refers to a straight line 4 cm stretching downwards and 3.5 cm from both sides of the posterior point of the anteroposterior midline and parallel to the midline (see Fig. 117).
Indications: Ataxia due to cerebellar diseases and paraequilibrium.
(11) Stomach Zone:
Location: It refers to a straight line 2 cm stretching upwards from the hair line directly over the pupil and parallel to the midline (see Fig. 118). 
Indications: Gastritis and epigastric discomfort.  
(12) Thoracic Cavity Zone:
Location: Between the stomach zone and the anteroposterior midline, two straight lines 2 cm stretching from the hairline upwards and downwards respectively and parallel to the midline (see Fig. 118).
Indications: Asthma and thoracic discomfort.
(13) Reproduction Zone:
Location: It refers to a straight line 2 cm stretching upwards from the frontal angle and parallel to the anterioposterior midline (see Fig. 118).
Indications: Dysfunctional uterine bleeding, pelvic inflammation and hysteroptosis.
