Extended Data Fig. 4. Input onto feedback neurons.

Extended Data Fig. 4

Figure shows the fractions of total dendritic input each pre-modulatory neuron (FBN, FB2N or FFN) receives from KCs, modulatory neurons, MBONs, FBNs, FB2Ns, FFNs, and from other non-MB neurons (others). a FBNs receive on average 12% of their inputs directly from MBONs and most of them also receive inputs from other FBNs, with an average of 26% from MBONs and other FBNs combined (see also Supplementary Figure 4a). b FB2Nsreceive inputs both from FBNs (on average 17%) and from other FB2Ns (on average 28% from FBNs and FB2Ns combined).Many feedback neurons also receive a significant fraction of input from other unknown neurons from other brain areas (other than MB), suggesting that the feedback about the learnt valences of stimuli is integrated with or modulated by other information. c Tables show percent of inputs onto FBNs (top) and FB2Ns (bottom) from MBONs, FBNs, FB2Ns, FFNs, modulatory neurons and Kenyon cells.
