The operation principle of ultra micro scalp electrode array is as shown in figure 9, during the decline of ultra micro scalp electrode array module, due to super
Micro- scalp electrode head is tiny, body portion is elongated, the scalp so ultra micro scalp electrode head can go directly through scalp surface hair
Surface.When ultra micro scalp electrode head is in contact with scalp A, under the upward resistance of scalp, ultra micro scalp electrode is with surpassing
Micro- scalp electrode array module produces relative motion, and spring is compressed, and because head part is circle, scalp surface has radian,
And scalp surface hair follicle, grease etc. make scalp surface be uneven, different ultra micro scalp electrodes and electrode in electrod-array module
The amplitude of array module relative motion is different, under the action of the spring, and each ultra micro scalp electrode head is and scalp
Intimate surface contact is protected, and so both ensure that adaptation of each ultra micro scalp electrode to scalp surface radian and injustice, while
It ensure that each ultra micro scalp electrode and the good electric conductivity of scalp.Although each ultra micro scalp electrode head and scalp contact surface
The equal very little of product, but due in ultra micro scalp electrode array module by multiple ultra micro scalp electrodes constitute array can averraged it is super
The bright pressure of the correct epidermis of micro- scalp electrode array, and spring also buffered ultra micro scalp electrode head correct epidermis is bright rushes
Hit, so just will not produce damage and sense of discomfort to scalp surface.
As shown in figure 1, the cortex magnetic signal writing unit is made up of multiple positioned at stereotaxis magnetic head in headpiece case
Stereotaxis magnetic head arrays 3-B composition, the connecting wire of each stereotaxis magnetic head collect to helmet data wire 4-5 and with it is upper
Position equipment connection.As shown in fig. 6, stereotaxis magnetic head arrays 3-B is positioned over corresponding to cerebral cortex somatesthesia maincenter 2-K
Scalp surface, its low frequency magnetic field produced may pass through scalp and skull acts on somatesthesia maincenter 2-K.
As shown in Figures 10 and 11, stereotaxis magnetic head is by stereotaxis casing of magnetic head 2-1, pulsed magnetic field coil 2-2, arteries and veins
Rush magnetic field lead 2-3, multiple magnetic field Stereo-control coil 2-4, magnetic field guiding circular cone ring 2-5, pulsed magnetic field coil branch

The lower end of enclosure, the plurality of magnetic field Stereo-control coil passes through the 2-E connections of Stereo-control coil connecting leads
Onto magnetic field Stereo-control coil control unit, the magnetic field is oriented to the bottom that circular cone ring is arranged on stereotaxis casing of magnetic head
Portion.
The stereotaxis casing of magnetic head is used for shielding direct current using the material (such as permalloy and aluminium) of high magnetic permeability
Magnetic field and low-frequency AC magnetic fields, so as to prevent influencing each other for the magnetic field that adjacent stereotaxis magnetic head produces in itself.The arteries and veins
Rushing field coil is used to produce pulsed magnetic field (magnetic induction line produced for pulsed magnetic field coil that 2-B is pointed in such as Figure 11).It is described
Pulsed magnetic field lead uses metal material, and pulsed magnetic field pole can be made to be distributed to by lead y direction, under the lead
Turbination is held into, magnetic strength line density can be controlled.The multiple magnetic field Stereo-control coil is uniformly distributed in annular shape,
Magnetic field produced by them is in circular (magnetic induction line produced for Stereo-control coil that 2-A is pointed in such as Figure 11), often
Pole is to identical on the longitudinal axis for the magnetic field of individual control coil formation and pulsed magnetic field that pulsed magnetic field coil is formed, therefore two kinds of magnetic field phases
Mutually repel, when the magnetic field annulus that the pulsed magnetic field of pulsed magnetic field coil formation is formed by multiple control coils, pulsed magnetic field
The pulsed magnetic field of coil formation will be compressed into downward coniform in tip, and pulsed magnetic field energy density will focus on circular cone tip
(2-C points in such as Figure 11), the power in magnetic field is produced by adjusting control coil, changes the pulsed magnetic field of pulsed magnetic field coil formation
Shape, so as to so that 2-C points are moved up and down in pulsed magnetic field coil y direction, so as to realize stereotaxis purpose.Arteries and veins
The pulsed magnetic field energy centrostigma (the 2-C points in Figure 11) of field coil formation is rushed, the energy intensity of the point can just make position
Film potential is produced in the Cerebral Cortex Neuronal Cells of the point, and magnetic field other parts energy intensity is unable to reach brain cortex neural
Cell produces the threshold value of film potential, and brain skin corresponding to the point can be accurately controlled by adjusting the point in corticocerebral position
The Cellular electrical activity in layer function area.It is that internal orifice dimension is big on inverted trapezoidal annulus wide at the top and narrow at the bottom, annulus that the magnetic field, which is oriented to circular cone ring,
In lower internal orifice dimension, annulus uses the material (such as permalloy and aluminium material) of high magnetic permeability, for shielding D.C. magnetic field and low
Frequency AC magnetic field, and pilot pulse field coil produce magnetic field from annulus endoporus export；Stereo-control line is shielded simultaneously
Leak in the magnetic field of circle.The pulsed magnetic field coil brace disk is used to support simultaneously fixed pulse field coil, and it uses plastic material
It is made, not to magnetic fields.The magnetic field Stereo-control coil brace disk is used to support and fixed magnetic field solid is fixed
To control coil, it uses plastic material to be made, not to magnetic fields.The pulsed magnetic field coil connecting leads 2-D is used
In connection pulsed magnetic field coil and pulsed magnetic field coil control unit, its outer wrap electromagnetic shield rubber layer prevents three-dimensional fixed
Electromagnetic interference inside to magnetic head.The multiple magnetic field Stereo-control coil 2-E is used to connect multiple magnetic field stereotaxis controls
Pass through stereotaxis between coil processed and magnetic field Stereo-control coil control unit, each magnetic field Stereo-control coil
Control coil connecting wire 2-F is cascaded, above-mentioned connecting wire outer wrap electromagnetic shield rubber layer, prevents stereotaxis
Electromagnetic interference inside magnetic head.Above-mentioned pulsed magnetic field coil connecting leads 2-D, Stereo-control coil connecting leads 2-E are imported
Wire outer tube 2-G simultaneously guides upper equipment into.
The stereotaxis magnetic head arrays 3-B constitutes closely spaced array by multiple stereotaxis magnetic heads 3, each stereotaxis
Magnetic field intensity that the pulsed magnetic field coil of magnetic head is produced, pulse frequency, magnetic field pole are to by pulsed magnetic field coil control unit list
Solely regulation and control；Each Stereo-control coil magnetic field intensity, magnetic field pole are single to being controlled by magnetic field Stereo-control coil
First individually regulation and control.Therefore, stereotaxis magnetic head arrays, which will be produced, to position, codified, with subject brain cortical neurogenic cell group
The complicated pulsed magnetic field that neural electrical activity matches.
