Micropolarization
a non-invasive, safe and painless brain stimulation technique

What is micropolarization?

Mi­cro­po­la­ri­za­tion of the bra­in or trans­cra­nial di­rect cur­rent sti­mu­la­tion (TDCS) is a pro­mi­sing tech­ni­que for no­n-i­nva­si­ve, sa­fe and pa­in­less bra­in sti­mu­la­tion, which is used in neu­ro­re­ha­bi­li­ta­tion of pa­tients with bra­in da­ma­ge and va­rio­us neu­ro­lo­gi­cal dys­func­tions.

The con­se­qu­en­ces of bra­in da­ma­ge are not on­ly a re­sult of the da­ma­ge it­self. They are al­so the ef­fect of the dy­na­mic func­tio­nal chan­ges ta­king pla­ce in the da­ma­ged neu­ral ne­tworks and si­mul­ta­ne­ously are a con­se­qu­en­ce of the be­ha­vio­ral in­ter­ce­re­bral ba­lan­ce di­sor­der.

How does it work?

Di­rect elec­tri­cal cur­rent (DC) with in­ten­si­ty 0,08–2mA and con­si­stent di­rec­tion cau­ses neu­ro­mo­du­la­tion of the cor­ti­cal cen­ters that can be pre­se­rved by cyc­lic re­pe­ti­ti­ve­ness of in­duc­tions. Mi­cro­pol­ri­za­tion the­re­fo­re pro­du­ces a con­trol­led chan­ge in cor­ti­cal exci­ta­bi­li­ty.

The na­tu­re of neu­ro­mo­du­la­tion is de­pen­dent on the ty­pe of elec­tro­de – the ca­tho­de (c-tDCS) de­cre­ases and the ano­de (a-tDCS) in­cre­ases the le­vel of cor­ti­cal exci­ta­tion. Uni­la­te­ral bra­in da­ma­ge, eg. With in­ju­ry or stro­ke le­ads to an in­ter­he­mi­sphe­ric im­ba­lan­ce – da­ma­ged he­mi­sphe­re has low ac­ti­vi­ty, not on­ly due to the de­struc­tion of ne­rve tis­sue but al­so as a re­sult of in­hi­bi­tion cau­sed by the com­pe­ti­ti­ve, hyperac­ti­vi­ty of the struc­tu­ral­ly in­tact he­mi­sphe­re.  The­re­fo­re in or­der to re­sto­re the ba­lan­ce of sti­mu­la­tion the ano­de is used on the da­ma­ged he­mi­sphe­re and ca­tho­de on the he­al­thy he­mi­sphe­re. Tran­scra­nial electrosti­mu­la­tion acts mo­du­la­ting on sy­nap­ti­cand extra­sy­nap­tic pro­ces­ses in terms of phy­sio­lo­gi­cal bor­ders and streng­thens the spon­ta­ne­ous pro­ces­ses of nor­ma­li­za­tion.

Tran­scra­nial sti­mu­la­tion can be ap­plied to mo­tor, so­ma­to­sen­so­ry, vi­su­al and pre­fron­tal cor­tex af­fec­ting co­gni­ti­ve, per­cep­ti­ve and mo­tor func­tions, ena­bling and ac­ce­le­ra­ting ef­fec­ti­ve­ly re­ha­bi­li­ta­tion of pa­tients with neu­ro­lo­gi­cal di­sor­ders. Neu­ro­mo­du­la­tion with di­rect cur­rent can fa­vo­ra­bly mo­du­la­te the ac­ti­vi­ty of di­stur­bed neu­ro­nal cir­cu­its, pa­ve the na­tu­ral ca­sca­de of sel­f-he­aling pro­ces­ses ac­ti­va­ting the phe­no­me­non of neu­ro­pla­sti­ci­ty, as well as pro­mo­te  mo­tor, co­gni­ti­ve, spe­ech and me­mo­ry tra­ining, and al­so per­cep­tion and con­cen­tra­tion. The best ef­fect is achie­ved by com­bi­ning trans­cra­nial mi­cro­po­la­ri­za­tion wi­thas neurore­ha­bi­li­ta­tion, asat the ba­se of po­la­ri­za­tion and be­ha­vio­ral le­ar­ning pro­ces­ses the­re are the sa­me neu­ral me­cha­ni­sms and elec­tri­cal­ly in­du­ced cor­ti­cal pas­si­ve mo­du­la­tion spe­eds up and fa­ci­lia­tes oc­cu­ren­ce of the ma­xi­mal ef­fect after phy­sio­the­ra­py tra­ining.
