TDCS (Transcranial Ncaj Ncees Tam Sim No)

Hauv Phau Ntawv Qhia no, kuv yuav:

1. Taug kev koj los ntawm kev tsim cov cuab yeej TDCS yooj yim.

3. Layout the theory behind the circuits.

2. Qhia qee qhov kev tshawb fawb thiab piav qhia vim li cas cov cuab yeej zoo li no thiaj tsim nyog ua.

4. Layout qee cov ntaub ntawv ntxiv uas koj tuaj yeem tshawb nrhiav thiab txuas rau cov peev txheej muaj txiaj ntsig uas tau pab kuv ua txoj haujlwm no, thiab yuav pab koj txhim kho qhov kuv tau ua.

Kauj Ruam 1: Kauj Ruam 1: Yuav/Tsim Cov Hluav Taws Xob

Yuav

Muaj ntau qhov chaw yuav cov electrodes rau TDCS.

Cov khoom siv hluav taws xob tuaj yeem ua tau raws li hauv qab no:

-Kev nplaum

- Roj Hmab Carbon Electrodes

- Daim txhuam cev Electrodes

- Amrex Spong Electrodes

- DIY Electrodes

Tsim

Kuv tsim kuv tus kheej electrodes siv cov ntaub ntawv hauv qab no:

• Caps ntawm Snapple fwj ($ 1/ib)
• Daim ntawv khawm
• Daim kab xev hluav taws xob
• Tsev Sponges (txiav qhov ntev ib nrab, 1/4-inch dav)
• Dej
• Ntsev

Cov duab tuaj yeem pom saum toj no.

Nco tseg: Txhawm rau tsim cov txiaj ntsig zoo pom hauv daim txhuam cev, muab 1 lossis 2 daim txhuam cev tso rau hauv nruab nrab ntawm lub hau ua ntej muab daim txhuam cev txiav daim txhuam cev tso rau hauv lub hau. Tsis tas li, kho ib qho ntawm ob txoj kab txuas ntawm lub khawm rau lub hau kom tuav nws nyob rau hauv qhov chaw, thiab siv cov kab xev hluav taws xob hla nws txhawm rau txhawm rau txhawm rau lub hau kom tsim kev sib cuag tau zoo.

Kauj Ruam 2: Txuas Txhua Lub Cheeb Tsam

Siv Circuit Diagram raws li Qhia

Txhua lub Cheebtsam tau muab tso ua ke raws daim duab qhia chaw kom pab nrog kev sib txuas.

Ntawm qhov kawg ntawm cov hlau lead, txuas cov hlau lead rau cov kab hluav taws xob.

Thaum npaj txhij los koom nrog lub cuab yeej, tig qhov hloov mus rau ntawm txoj haujlwm, thiab ntsuas cov hluav taws xob nrog lub ntsuas hluav taws xob, yog tias ua tau.

Kauj Ruam 3: Tsim Cov Tshuaj Ntsev rau Cov Sponges thiab Muab Daim Phiaj Ncauj Rov Qab rau hauv Electrode Cap

Nyeem Kev Tso Hluav Taws Xob thiab Kev Sib Tham Hauv Qab Hauv qab no

Cov lus qhia ntawm daim txhuam cev DIY

1. Muab dej thiab ntsev hauv tsev (NaCl) ntawm 2.3 grams rau 8 oz dej.

2. Muab daim txhuam cev tso rau hauv dej.

3. Siv cov dej txaus kom zoo li cov sponges tsis ntws, tab sis lawv tseem ntub rau qhov kov (dej tsawg dua yog zoo dua dej ntau dhau rau cov dej faib los ntawm electrode - kawm)

4. Ua kom ntseeg tau tias lub Circuit tsis sib txuas/tua tawm thiab muab daim txhuam cev rov qab rau hauv lub kaus mom

Yuav Cov Ntawv Qhia Sponge

1. Salong sponges lossis electrodes raws li qhov tshwj xeeb ntawm koj cov khoom lag luam.

2. Muab cov sponges tso rau qhov kawg ntawm cov electrode.

Kauj ruam 4: Sib tham

Vim li cas TDCS?

TDCS yog ib hom neuromodulation uas siv hluav taws xob me me los tsim qhov tob, thiab kev txhim kho kom muaj nuj nqis hauv kev paub thiab lub cev. Muaj ntau qhov kev tshawb fawb tau ua tiav ntawm qhov kev kawm - qee qhov ua tiav, thiab qee qhov tsawg dua. Kuv yuav suav nrog ntau cov ntaub ntawv tshawb fawb uas tau sim lub cuab yeej thiab txuas rau lwm qhov blog tshawb fawb tsawg dua uas suav nrog cov ntsiab lus ntawm cov neeg uas tau sim ntawm lawv tus kheej.

Leej twg siv TDCS?

Kev sim neuroscientists, kws paub txog kev puas siab puas ntsws transhumanist fanatics, txhim kho tus kheej hobbyists, xav tinkerers, thiab ntau ntxiv.

Puas yog nyab xeeb?

Muaj ntau qhov kev tshawb fawb txog dab tsi muaj kev nyab xeeb thiab dab tsi tsis nyab xeeb nrog neurostimulation/neuromodulation. Kev tshawb fawb feem ntau tau pom tias kev txhawb hluav taws xob qis <2.5 mA tsis pub ntev tshaj 30 feeb yog kev nyab xeeb rau lub hlwb thiab lub cev. Qee tus kws tshawb fawb thiab cov neeg txaus siab tau tshaj tawm qhov ua rau tawv nqaij me me, tab sis yog tias lub cuab yeej siv tau zoo, nyob rau qhov tau hais tseg tam sim no thiab sijhawm ntau lub cuab yeej tsis muaj kev phom sij.

Qhov Kev Tso Hluav Taws Xob Zoo Li Cas?

Kev tso hluav taws xob kom zoo sib txawv heev thiab txiav txim siab los ntawm cov txiaj ntsig uas koj xav tau. Piv txwv li, yog tias koj xav tau "kawm nrawm dua," koj yuav tsum tso cov hluav taws xob zoo ntawm koj lub tuam tsev sab laug raws li cov lus qhia ntawm kev tshawb fawb ua los ntawm DARPA. Yog tias hloov chaw, koj xav txhim kho koj txoj kev xav thiab pab nrog kev nyuaj siab, koj yuav tsum tso cov cathode ntawm sab xis supraorbital thiab anode ntawm sab laug DLPFC. Yog xav paub ntxiv txog cov chaw no nyob qhov twg, nrog rau kev tshawb fawb uas txhawb nqa lawv pom txuas. Hauv qab ntawm txhua "kev txiav tawm," koj tuaj yeem pom cov kev tshawb fawb cuam tshuam nrog txhua lub tswv yim tso hluav taws xob.
