Summary

Automatic Translation

Optogenetic teknikker har gjort det muligt at studere bidrag fra bestemte neuroner til adfærd. Vi beskriver en metode i larvernes zebrafisk til aktivering enkelt somatosensoriske neuroner udtrykker et channelrhodopsin variant (kok) med en diode-pumpet solid state (DPSS) laser og registrere fremkaldte adfærd med en high-speed video kamera.
