Hluav taws xob stimulation ntawm neural thiab nqaij hlwb
Neural thiab nqaij hlwb yog hluav taws xob-excitable, piv txwv li lawv tuaj yeem txhawb nqa los ntawm hluav taws xob tam sim no. Nyob rau hauv tib neeg cov neeg mob, xws li stimulation yuav ua rau mob mob, nqaij spasms, thiab txawm lub plawv nres. Lub rhiab heev ntawm cov hlab ntsha thiab cov leeg hlwb rau hluav taws xob teb yog vim muaj qhov voltage-gated ion channels tam sim no nyob rau hauv lawv cov cell membranes. Stimulation threshold tsis txawv ntau ntawm cov zaus tsawg (hu ua rheobase-constant level). Txawm li cas los xij, qhov pib pib nce nrog txo lub sijhawm ntawm lub plawv dhia (lossis lub voj voog) thaum nws poob qis dua tus yam ntxwv yam tsawg kawg nkaus (hu ua chronaxie). Feem ntau, chronaxie ntawm neural hlwb nyob rau hauv thaj tsam ntawm 0.1-10 ms, yog li qhov rhiab heev rau hluav taws xob stimulation (inverse ntawm stimulation pib) txo nrog nce zaus nyob rau hauv lub kHz ntau thiab saum toj no. (Nco ntsoov tias zaus ntawm qhov hloov hluav taws xob tam sim no yog qhov hloov pauv ntawm lub sijhawm ntawm ib lub voj voog ib zaug). Txhawm rau txo qhov cuam tshuam ntawm cov leeg nqaij thiab neural stimulation, cov khoom siv electrosurgical feem ntau ua haujlwm hauv xov tooj cua zaus (RF) ntau ntawm 100 kHz txog 5 MHz.
Kev ua haujlwm ntawm ntau zaus kuj pab txo qis ntawm hydrogen thiab oxygen tsim los ntawm electrolysis ntawm dej. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev txiav txim siab rau cov ntawv thov hauv cov kua nruab nrab hauv cov thawv kaw, qhov chaw tsim cov npuas npuas tuaj yeem cuam tshuam nrog cov txheej txheem. Piv txwv li, npuas tsim thaum lub sijhawm ua haujlwm hauv lub qhov muag tuaj yeem ua rau pom qhov pom.
