2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Phau ntawv qhia no tau txais los ntawm cov peev txheej muaj npe nrov (txuas pdf)! Citation #10 hauv daim ntawv "Cov cuab yeej tshiab rau kev txhim kho kev puas hlwb - dab tsi txog neuroethics?" (Html txuas) Croat Med J. 2016 Lub Yim Hli; 57 (4): 392–394. doi: 10.3325/cmj.2016.57.392 ------- Qee qhov kev txhawj xeeb txog kev coj ncaj ncees ntawm cov haujlwm no, ceeb toom txog kev hloov pauv tus cwj pwm thiab cov tshuaj hormones los ntawm kev siv tDCS. Yog li kuv ntxiv qee qhov lus ceeb toom.

Qhov chaw rau kev tso tDCS sib txawv thiab cuam tshuam.

Saib qhov haujlwm no hauv cov ntsiab lus ntawm kuv lub neej thiab lub hom phiaj ntawm kuv tus kheej ntawm no yog tias koj xav tau.

Kho: Yog tias koj xav kom kho vajtse ua tACS thiab tRNS ntxiv rau tDCS, Kuv tau tsim qee qhov ntawd ib yam.

Kuv xav tsis thoob thiab txaus siab kawm paub tias tib neeg txhim kho cov thev naus laus zis tsis yog tsuas yog muaj nyob, tab sis nyob hauv kev ncav cuag ntawm cov khoom siv hluav taws xob yooj yim. Cov lus qhia no yog (tau kawg) rau lub hom phiaj kev kawm nkaus xwb thiab koj tuaj yeem ua txhaum txoj cai hauv nroog los ntawm kev tsim thiab/lossis siv cov cuab yeej piav qhia ntawm no. Tus sau phau ntawv qhia no tsis lav paub txog qhov kub hnyiab, puas tsuaj rau lub paj hlwb tas mus li, lossis lwm yam kev raug mob ntawm tus kheej txog thiab suav nrog kev vwm thiab/lossis qaug dab peg thiab/lossis kev sib cais thiab/lossis kev puas tsuaj thiab/lossis kev tuag uas yuav tshwm sim los ntawm kev tsim thiab siv lub cuab yeej piav nyob ntawm no.

Transcranial Ncaj Ncees Tam Sim No (tDCS) yog ib txoj hauv kev hloov pauv sab nrauv neural uas siv qhov me me tam sim no khiav los ntawm lub hlwb txhawm rau hloov pauv cortical excitability. Cov ntsiab lus ntawm cov txheej txheem ntawm kev nqis tes ua thiab txhim kho qhov tseeb tuaj yeem ua tau dhau qhov ntawm tsab xov xwm no, tab sis koj tuaj yeem tshuaj xyuas cov khoom lag luam uas muaj muag, thiab saib cov ntaub ntawv kev nyab xeeb thiab kev tshuaj xyuas zoo ua ntej txiav txim siab yog tias qhov no yog yam koj xav ua. Qee qhov kev tshawb fawb hauv google yuav dhau los ua qhov txaus nyiam ib yam.

Daim duab ntawm nplooj ntawv no yog los ntawm kab lus no.

Kauj Ruam 1: Lub hauv paus ntsiab lus ntawm Kev Ua Haujlwm

Yog tias koj tsis xav txiav txim siab theoretical hauv paus rau kev ua haujlwm ntawm lub voj voog no, hla cov kauj ruam no. Cov kab hluav taws xob tau qhia yog qhov tswj hwm lub dab dej tam sim no. Koj tuaj yeem pom nws yog lub tsev tsim muaj txiaj ntsig hauv koj cov phiaj xwm yav tom ntej. Nws tswj hwm qhov tam sim no los ntawm R [L], tiv thaiv nws los ntawm ntau dua tus nqi teeb tsa. Lub voj voog no tsis muaj peev xwm tsav lub zog, txawm li cas los xij, thiab yog li V [DRIVE] yuav tsum loj txaus los tsav qhov xav tau tam sim no los ntawm R [L]. Tam sim no dhau R [L] yog sib npaug rau kuv [C]. Kuv [C] yog sib npaug sib npaug rau (V [REF] - (V [BE] ntawm T1)) / R [LIM]. Txhawm rau pom qhov twg qhov sib npaug no pib, pib los ntawm kev sau cia tias qhov sib npaug ntawm qhov hluav taws xob nyob ib puag ncig lub voj tsim los ntawm V [REF], lub hauv paus-emitter sib txuas ntawm T1, thiab R [LIM] yuav tsum yog xoom (los ntawm Kirchhoff txoj cai hluav taws xob): V [REF] - V [BE] - V [RLIM] = 0 so V [RLIM] = V [REF] - V [BE]. Tam sim no los ntawm R [LIM] (tseem hu ua I [E]) tau txhais los ntawm Ohm txoj cai, thiab peb tuaj yeem hloov pauv siv qhov sib npaug yav dhau los: Kuv [E] = V [RLIM] / R [LIM] = (V [REF)] - V [BE]) / R [LIM]. Tsis quav ntsej lub hauv paus tam sim no, Kuv [C] = Kuv [E], yog li tam sim no los ntawm qhov ntsuas qhov ntsuas tau kwv yees txhais los ntawm kuv [LOAD] = Kuv [C] = (V [REF] - V [BE]) / R [LIAM]. Yog tias koj xav suav nrog qhov cuam tshuam ntawm lub hauv paus tam sim no ntawm transistor, koj yuav tsum tseem cuam tshuam rau qhov nce tam sim no ntawm transistor, h [FE]. Saib cov transistor ua ib qho, los ntawm Kirchhoff txoj cai tam sim no, 0 = Kuv [C] + Kuv [B] - Kuv [E] yog li kuv [B] = Kuv [E] - Kuv [C]. Peb paub tias h [FE] yog qhov tseem ceeb peb tuaj yeem sib tw los ntawm kuv [B] txhawm rau nrhiav peb li kuv [C]. Yog li, kuv [B] * h [FE] = Kuv [C]. Hloov pauv rau kuv [B] los ntawm qhov sib npaug yav dhau los, (Kuv [E] - Kuv [C]) * h [FE] = Kuv [C]. Kev daws rau kuv [C], Kuv [C] = Kuv [E] - (Kuv [E] /(1 + h [FE])), thiab txij li thaum kuv [E] = (V [REF] - V [BE]) / R [LIM], qhov sib npaug uas tseeb dhau los ua: I [C] = ((V [REF] - V [BE]) / R [LIM]) - (((V [REF] - V [BE])) / R [LIM]) / (1 + h [FE])).

Kauj Ruam 2: Kev Koom Tes Ua Haujlwm

Nov yog cov phiaj xwm ntawm kev ua haujlwm 2mA cov khoom siv tam sim no uas tuaj yeem siv rau tDCS. Nws yog ua raws tus tswj hwm transistor tau piav qhia hauv cov kauj ruam dhau los. Ib feem tau ntxiv los tso rau/tawm kev ua haujlwm, ntawm lub xeev kev qhia, thiab ntsuas ntsuas kev nyab xeeb tsis tu ncua. --- PARTS LIST --- B1: 4 9V roj teeb clips, teeb tsa (ntxiv 9V roj teeb los muab lub zog) S1: SPST hloov D1: ntsuas LED D2-D4: 1n400x (Kuv siv 1n4003) T1: TIP31C (lossis TIP29C) R1, R2: 12 kohm 250mW R3, R4: 2.2 kohm 250mW R5: 560 ohm 250mW R6: 100 ohm 250mW Hlau thiab gel electrodes tau yooj yim pom muag rau TENS cov cuab yeej, tab sis yuav tso cai tDCS, txawm hais tias tsuas yog hauv cov cheeb tsam uas tsis muaj plaub hau. Muaj lwm txoj hauv kev, txawm li cas los xij, thiab daim txhuam cev hluav taws xob tsis zoo yuav ua rau cov hluav taws xob hlawv.

Thawj qhov lus pom thawj zaug ntawm kev sau ntawv, pheej yig tshaj, tab sis tsuas yog siv tau rau ntawm daim tawv nqaij tsis muaj plaub hau thiab tej zaum yuav ua rau tawv nqaij ua rau tawv nqaij thiab puas tsuaj me me: W1: cov hlau lead ua (xws li cov TENS no ua)

Kev tshawb nrhiav rau "TENS electrode lead" yuav pom hom tsim nyog

www.amazon.com/s/ref=nb_sb_noss_1?url=searc…

E1, E2: gel electrode los (tseem muag rau TENS units)

Tshawb nrhiav "TENS gel electrodes", Kuv pom zoo 2 "x 2" square gel electrodes

www.amazon.com/s/ref=nb_sb_noss_1?url=searc…

Cov lus qhia tshiab 1: daim txhuam cev electrodes uas sib xws nrog 2mm tus pin txuas tsis siv cov gel electrodes. Qhov ntawd yog qhov txuas ntawm ebay, txawm li cas los xij, tshaj tawm 2016-10-24, thiab nws yuav tsis nyob nyob / Kuv tsis tuaj yeem pom lwm tus muag nrog 2 hli sib xws daim txhuam cev hluav taws xob tam sim no.

Cov lus qhia tshiab 2: Txiv tsawb ntsaws hloov TENS cov hlau lead ua thiab Amrex daim txhuam cev electrodes. Cov hluav taws xob daim txhuam cev yog $ 20 txhua, txawm li cas los xij, tsis yog $ 10 rau ib khub zoo li cov lus qhia tshiab 1.

Cov lus qhia tshiab 3: Tus txiv leej tub hauv cov lus uas tau tsim qhov no, ElChevere, siv rab diav thiab chav ua noj ua haus txhuam rau hluav taws xob, uas kuv tau pom zoo tag nrho vim nws yog qhov pheej yig tshaj / txoj hauv kev zoo tshaj kom tau txais daim txhuam cev electrodes nrog feem ntau muaj:)

Perfboard yog qhov zoo tshaj plaws rau kev sib dhos Circuit Court no mus tas li. Cov kua nplaum kub yaj yog qhov muaj txiaj ntsig zoo rau txuas cov xov hlau nyob hauv qhov chaw kom tiv thaiv kev sib kis.

Kauj Ruam 3: Kev Xeem thiab Kev Pov Thawj Zoo

Thaum koj lub cuab yeej tsim kho, koj yuav tsum ntsuas nws ua ntej ua raws nws lub taub hau thiab lub cev thiab ua kom nws ua haujlwm. Txheeb xyuas qhov luv-Circuit tam sim no tso tawm nrog ammeter. Tus nqi yuav tsum yog 2 mA +/- 10%. Muaj kev lom zem. Sim ua kom zoo dua qub. Saib mus rau hauv piracetam tab sis nco ntsoov tias nws zoo li ua haujlwm zoo tshaj plaws thaum noj nrog choline ntxiv. Hmoov zoo.
