- 10:02Conclusion
Optogenetic tilgange er meget udbredt til at manipulere neurale aktivitet og vurdere konsekvenserne for hjernens funktion. Her er en teknik, skitseret, at ved in vivo-ekspression af det optiske aktivator Channelrhodopsin, giver mulighed for ex vivo analyse af synaptiske egenskaber af særlig lang rækkevidde og lokale neurale forbindelser i frygt-relaterede kredsløb.
