Connectivity analysis for medulla layer 6 (M₆) output neurons MT, ipsilateral MV, and contralateral MV. (a) Three representative MT neurons of the M_R6‐dT_R3 subfamily. (b) Three representative MT neurons of the M_R6‐vT_R2 subfamily. Brain structures immunostained with anti‐DLG antibodies (blue). (c–d) Spatial distributions of three representative MT neurons of the same subfamily. Each MT neuron is registered to a standard brain and is shown in a different color. (e–f) Gray indicates the innervation patterns of MT neurons between medulla layer 6 (M₆) domains and lateral anterior optic tubercle (L‐AOTU) glomeruli. (g) Three representative ipsilateral MV neurons of different subfamilies. Brain structures immunostained with anti‐DLG antibodies (blue). (h) Spatial distribution of three representative ipsilateral MV neurons of different subfamilies. Each ipsilateral MV neuron is registered to a standard brain and shown in a different color. (i) Gray indicates the innervation patterns of MV neurons between M₆ domains and ipsilateral ventral medial protocerebrum (VMP) domains. (j) Two representative contralateral MV neurons of different subfamilies. Brain structures immunostained with anti‐DLG antibodies (blue). (k) Spatial distribution of two representative contralateral MV neurons of different subfamilies. Each contralateral MV neuron is registered to a standard brain and shown in a different color. (l) Gray indicates the innervation patterns of contralateral MV neurons between M₆ domains and contralateral VMP domains. Images are frontal views of confocal projections of several adjacent optical sections unless otherwise specified. Scale bars: 20 μm [Color figure can be viewed at wileyonlinelibrary.com]
