Columnar, commissural neuron, connecting both lobula complexes. a COcom-neuron (columnar commissural neuron of the outer lobes) reconstruction, anterior view. Neuron ramifies in outer lobes of both LOX and in central brain. b, c Maximum projections of confocal horizontal (posterior to anterior orientation; top) and frontal sections (dorsal to ventral orientation; bottom) through outer lobe 1 and 2 in right (b) and left (c) optic lobe. Terminal neurites are strongly beaded in right (b) and smoother in left optic lobe (c). d Measured (left) and modelled (right) response fields for neuron in (a, b, c) for flashed dark bars. e response of same neuron to spiralling disc. f Maximum projection of confocal microscopy slices through left side of praying mantis brain (posterior view), showing several COcom-neurons stained during the experiment that culminated in the recording of neuron rr170117 (response in j). OLO1 outer lobe 1 of LOX, OLO2 outer lobe 2 of LOX. gk as d for five further COcom-neurons (see Supplementary Fig. 3 for fitted receptive fields and responses to bright bars for two neurons). Response field headers provide outcome of two-way-ANOVA with “L” (“R”) being significant left (right) eye input and “I” significant interaction term (see Table 1), otherwise “ns” meaning not significant. l, Fitted receptive fields for neuron in (k)
