1. ablation af en delpopulation af neuroner ved hjælp af en to-foton Laser mikroskop
Bemærk: Hvis brugere har planer om at udføre Ca imaging følgende ablation, brug UAShspzGCaMP6s linje21. Hvis brugere har planer om at udføre adfærdsmæssige optagelse efter ablation, bruge linjen UAS:EGFP ablation af EGFP-positive celler er lettere at udføre end GCaMP6s-udtrykker celler.

Selvom to-foton laser har en fremragende rumlige opløsning til specifikt ablate individuelle neuroner, bør der udvises stor forsigtighed at undgå uønskede skader på hjernevævet på grund af varmen. Det vigtigste skridt i ablation eksperiment er at bestemme den optimale mængde af laser bestråling. Utilstrækkelig bestråling undlader at dræbe neuronerne. For meget bestråling vil varme-skader det omkringliggende væv, som vil resultere i uønskede virkninger. Den optimale vifte af laser bestråling (områder af R...

For at forstå hvordan adfærd udspringer af neuronal aktivitet i hjernen, er det nødvendigt at identificere de neurale kredsløb, der er involveret i generation af denne adfærd. På stadiet larve i zebrafisk giver en ideel dyremodel for at studere hjernefunktion er forbundet med adfærd fordi deres lille, gennemsigtig hjerner gør det muligt at undersøge neuronal aktivitet på et cellulært opløsning i et bredt område af den hjernen mens observere adfærd1. Billeddannelse af neuronal aktivitet i specifikke neuroner er blevet mulig gennem opfindelsen af genetisk kodet calcium (Ca) indikatorer (GECIs) som GCaMP2. GCaMP transgene zebrafisk har vist sig for at være nyttige for knytte den funktionelle neurale kredsløb med adfærd ved at foretage Ca imaging i opfører dyr3.
Mens Ca imaging kan påvise sammenhænge mellem neuronal aktivitet og adfærd, for at vise kausalitet, undertrykkelse af neuronal aktivitet og teste sin consequence(s) på adfærd er vigtige skridt. Der er forskellige måder at opnå dette: brug af genetiske mutation, der ændrer specifikke neurale kredsløb4, udtryk for nervegifte i specifikke neuroner5,6, brug af optogenetic værktøjer som halorhodopsin7, og laser ablation af målrettede neuroner8,9. Laser ablation er især velegnet til at fjerne aktivitet i et relativt lille antal specifikke neuroner. Irreversibel eliminering af neuronal aktivitet ved at dræbe neuroner letter vurdering af adfærdsmæssige konsekvenser.
En interessant adfærd, som kan observeres på stadiet larve i zebrafisk er bytte capture (fig. 1A). Denne visuelt styret, målrettet adfærd giver en gunstig eksperimentel system for studiet af synsskarphed10, visuomotor transformation11,12,13, visuel perception og anerkendelse af objekter14,15,16,17,18, og beslutningstagning19. Hvordan bytte er anerkendt af rovdyr og hvordan bytte opdagelse fører til bytte fange adfærd har været et centralt spørgsmål i Neuroetologi20. I dette papir, vi fokusere på rollen som den pretecto-hypothalamus kredsløb dannet ved projektioner af en kerne i pretectum (nucleus pretectalis superficialis pars magnocellularis, herefter blot noteret som pretectum) til ILH. Laser-ablation af pretectum blev vist sig at reducere bytte capture aktivitet og afskaffe neuronal aktivitet i den ILH, der er knyttet til visuelle bytte perception21. Her, laser protokoller til at udføre ablation og teste sin virkning ved hjælp af Ca2 + imaging og adfærdsmæssige optagelse i zebrafisk larver er beskrevet.

ablation of a neuronal population using a two-photon laser and its assessment using calcium imaging and behavioral recording in zebrafish larvae

For at identificere rollen, en delpopulation af neuroner i adfærd, er det vigtigt at teste konsekvenser for at blokere sin aktivitet i levende dyr. Laser ablation af neuroner er en effektiv metode til dette formål, når neuroner er selektivt mærket med fluorescerende sonder. I den foreliggende undersøgelse, er protokoller for laser ablating en delpopulation af neuroner ved hjælp af en to-foton mikroskop og afprøvning af dets funktionelle og adfærdsmæssige konsekvenser beskrevet. I denne undersøgelse bruges bytte fange adfærd i zebrafisk larver som undersøgelse model. Pretecto-hypothalamus kredsløbet er kendt for at ligge til grund for denne visuelt drevet bytte fange adfærd. Zebrafisk pretectum var laser-ablated, og neuronal aktivitet i den ringere lap af hypothalamus (ILH, målet for den pretectal projektion) blev undersøgt. Bytte fange adfærd efter pretectal ablation blev også testet.

Specifikke neuroner var genetisk mærket med enten EGFP eller GCaMP6s, hvis udtryk blev drevet i Gal4 linjer. En Gal4 linje gSAIzGFFM119B blev brugt til at mærke en kerne i det pretectal område (magnocellular overfladiske pretectal kerne), og en delpopulation af olfaktoriske pære neuroner. En anden Gal4 linje, hspGFFDMC76A, blev brugt til at mærke ILH. Vi laser-ablated pretectal neuroner bilateralt (figur 2A venstre panel) og også ablate...
