Optogenetics tau tsim nyob rau lub sijhawm xyoo 2004 txog 2009. Cov kws tshawb fawb hauv ntau txhiab lub chaw kuaj mob thoob ntiaj teb tom qab pib siv optogenetics , thiab ntau txhiab qhov kev tshawb fawb tshawb fawb tau luam tawm nrog cov txheej txheem-chiefly hauv neuroscience tab sis kuj nyob rau lwm yam.
Thiab cov lus nug yog, leej twg invented optogenetics?
Tej zaum nws yuav yog Zhuo-Hua Pan invented optogenetics ua ntej. Txawm tias ntau tus kws tshawb fawb neuroscientists yeej tsis tau hnov txog Pan. Pan, 60, yog tus kws tshawb fawb txog qhov pom ntawm Wayne State University hauv Detroit uas tau pib nws txoj haujlwm tshawb fawb hauv nws lub tebchaws Suav.
Qhov thib ob, optogenetics ua haujlwm li cas? Feem ntau siv ion channel rau stimulation hauv optogenetics yog Channelrhodopsin-2. Cov kws tshawb fawb siv cov noob caj noob ces los nthuav qhia lub teeb-activated ion channel ntawm cov neurons hauv lub hlwb. Thaum lub teeb hits cov ion channel, lawv qhib thiab ions nkag mus rau hauv lub hlwb thiab ua rau lawv hluav taws.
Hauv qhov no, thaum twg optogenetics tau tshawb pom?
Cov khub, hauv kev koom tes nrog lawv cov npoj yaig, luam tawm ib daim ntawv qhia txog Nature Neuroscience (cited ntau dua 2, 100 zaug, raws li Google Scholar) hauv 2005 uas feem ntau suav tias yog qhov pib ntawm optogenetics.
Optogenetics puas tuaj yeem siv rau tib neeg?
Txog tam sim no optogenetics ua tau siv feem ntau yog cov cuab yeej tshawb fawb hauv tsiaj, txawm li cas los xij siv hauv tib neeg tsis suav tias ua tsis tau.

Thaum twg lub tshuab xam zauv Leibniz tau tsim?
Tsim los ntawm Leibniz nyob rau hauv 1673, nws tau siv rau peb centuries mus txog rau thaum lub advent ntawm lub tshuab xam zauv hluav taws xob nyob rau hauv nruab nrab-1970s. Leibniz tau tsim lub tshuab hu ua stepped reckoner raws li tus qauv tsim ntawm lub nruas kauj hauv xyoo 1694
LEEJ TWG ceeb toom FDR cov neeg German tau tsim riam phom atomic thiab US xav tau ua ib yam?
Xya caum tsib xyoos dhau los, Hungarian-American physicist Leo Szilard tau sau ib tsab ntawv mus rau Tebchaws Meskas Thawj Tswj Hwm Franklin Roosevelt qhia kev txhawj xeeb tias cov kws tshawb fawb German yuav sai sai no qhib qhov zais cia los tsim thawj lub foob pob tawg
Thaum twg DNA tau tsim thawj zaug?
Ntau tus neeg ntseeg tias American biologist James Watson thiab English physicist Francis Crick nrhiav DNA nyob rau hauv 1950s. Qhov tseeb, qhov no tsis yog li ntawd. Hloov chaw, DNA tau pom thawj zaug hauv 1860s lig los ntawm Swiss chemist Friedrich Miescher
Leej twg nrhiav tau optogenetics?
Zhuo-Hua Pan
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
