Figure 6. Paired recordings identify excitation from one glomerulus.

Figure 6

Top, paired in vivo recordings guided by PA-GFP. PA-GFP was expressed in many PNs (under the control of GH146-Gal4) and in NP6099 neurons. We photoactivated in a single glomerulus (either DP1m or VA2) to label the corresponding PN soma. We next we photoactivated the NP6099 neuron somata, and then simultaneously recorded from a PN and a LHN. Bottom, results from multiple experiments of this type (see Fig. 3b legend). Four of four DP1m pairs showed a connection. Only one of seven VA2 pairs showed a connection and this response was unusually weak.
