Hier beschrijven we een protocol voor het meten en analyseren van temperatuurresponsen in de reukbol van Xenopus laevis. Reukreceptorneuronen en mitralvormige cellen worden differentieel gekleurd, waarna calciumveranderingen worden geregistreerd, wat een gevoeligheid aangeeft van sommige neurale netwerken in de bol voor temperatuurdalingen die in de neus worden geïnduceerd.
