Denne protokoll er blitt brukt for å måle neural aktivitet av voksne sebrafisk in vivo. I praksis kan nevral aktivitet observeres konsekvent, skjønt de egenskaper (amplitude og form av hendelser) av den innspilte aktivitet kan variere mellom de enkelte fisker. Utnyttelse av den ekstracellulære opptaksteknikk kan forklare denne observasjonen. Fremgangsmåten gir mulighet for samtidig overvåkning av et stort antall celler i en region 1, slik at variasjoner i posisjoneringen av den primære elektro...

I denne artikkelen, er en protokoll som er beskrevet for å skaffe in vivo innspillinger av nevral aktivitet i voksen sebrafisk. Ekstracellulære opptaksmetoder brukes, og gir spenningsmålinger av elektrisk aktivitet innenfor et lite område av nervevev. Denne metode for undersøkelse involverer å overvåke et stort antall celler i et dyr oppfører seg en. Tidligere har slice opptak utført i både voksne og larver, som har øye cup forberedelser og elektroretinogrammet innspillinger. Disse eksperimentene har i stor grad blitt utført på detaljer fysiologiske responser av ulike sensoriske systemer 2-5. Inntil nylig har intakte hjerne forberedelser kun vært tilgjengelig for å utføre elektrofysiologi med sebrafisk larve 3,6,7, hvor respirasjon og oksygen diffusjon kan skje gjennom huden. Våre forberedelser gjør at innfødte nevrologiske aktiviteten til en voksen sebrafisk som skal måles mens dyret fortsatt er fullt bevisst og klar of sine omgivelser. Sebrafisk (Danio rerio) for tiden spiller en fundamental rolle som en modell for genetiske, toksikologiske, farmakologiske, og physiopathological studier tre. Sebrafisk har fått synlighet innen nevrovitenskap fordi de deler utstrakt homologi med pattedyr på genetisk, nevrale og hormonnivåer åtte. I løpet av det siste tiåret, har standard neuroanatomic og immunhistokjemiske teknikker blitt brukt til å bestemme detaljert karakteristisk organisering av sebrafisk nervesystemet 9-12 og av fordelingen av ulike nevrotransmittere 3,8,13. Mer nylig har forskere flyttet sitt fokus til funksjonelle studier 14,15, hvorav mange sentrumet på atferdsmessige prosesser 16-19 og elektrofysiologiske egenskapene av sensoriske systemer 2,13,20. Et lite antall av disse studiene har konsentrert seg om den elektriske aktiviteten i bestemte områder av adult sebrafisk hjerne 21-23, men ble ikke gjennomført ved hjelp av en in vivo tilnærming. Denne protokollen kan tilpasses for elektrofysiologiske studier av både spontan og evoked aktivitet innenfor sebrafisk nervesystemet å beskrive mønstre av aktivitet i bestemte områder av hjernen. Bruken av denne teknikken tillater sammenligninger gjøres mellom den nevrologiske aktiviteten til unge larvestadier og voksne. Videre tillater vår protokoll sammenligninger mellom genetiske eller farmakologiske endringer. Sammen med andre metoder, som genteknologi eller farmakologiske tester, har denne metoden en ny mulighet for funksjonell analyse av neuronal kommunikasjon og plastisitet i intakt voksne dyr, så vel som for mulige anvendelser, for eksempel studerer sen debut epilepsi eller neurodegenerative prosesser.

electrophysiological recording in the brain of intact adult zebrafish

Tidligere har elektrofysiologiske studier i voksen sebrafisk vært begrenset til å skjære preparater eller til øye cup forberedelser og electrorentinogram innspillinger. Dette dokumentet beskriver hvordan en voksen sebrafisk kan immobiliseres, intubert og anvendt for in vivo elektrofysiologiske eksperimenter, slik at opptak av nevral aktivitet. Immobilisering av den voksne krever en mekanisme for å levere oksygen til gjellene i stedet for buccal og opercular bevegelse. Med vår teknikk, er dyr immobilisert og perfundert med habitat vann for å oppfylle dette kravet. En kraniotomi er utført under Tricaine methanesulfonate (MS-222; Tricaine) anestesi for å gi tilgang til hjernen. Den primære elektrode blir så plassert inne i kraniotomi-vinduet for å ta opp ekstracellulært hjerneaktivitet. Gjennom bruk av et multitube perfusjons-system, kan en rekke farmakologiske forbindelser administreres til en voksen fisk og eventuelle forandringer i nerveaktivitetkan observeres. Metodikken gir ikke bare en observasjonene skal gjøres om endringer i nevrologisk aktivitet, men det gir også mulighet for sammenligninger gjøres mellom larve og voksen sebrafisk. Dette gir forskerne mulighet til å identifisere forandringer i neurologisk aktivitet på grunn av innføring av forskjellige forbindelser på forskjellige stadier.

Denne protokoll er blitt brukt for å måle neural aktivitet av voksne sebrafisk in vivo. Disse elektrofysiologiske målinger er konsekvent og reproduserbart oppnådd. Figur 5 viser et representativt eksempel på innfødte og induserte forandringer av nevral aktivitet hos en voksen sebrafisk når pentylentetrazol (PTZ), en felles chemoconvulsant 6,7,25,26, innføres i intubasjon setup. De innfødte nevrologiske aktiviteten av den voksne sebrafisk ble over...
