Temporal changes in temperature evoke ratiometric emission signals from yellow cameleon expressed in the AFD neuron of immobilized worms. A, In an immobilized worm expressing YC2.12 in the AFD neuron, as the temperature increases above a threshold of ∼17°C, the ratiometric emission signal from YC2.12 changes by ∼30% in a representative experiment, indicating changes in the level of intracellular calcium in the AFD neuron. B, The ratiometric emission signal from YC3.60 in the AFD neuron reports the same qualitative changes in the level of intracellular calcium, but with changes in the ratiometric emission signal of 200% in a representative experiment.
