Movie begins by showing morphological renderings of an individual EPG neuron that contacts an individual PFGs neuron in the PB. Later, PFGs pairs that innervate the left or right PB and share similar directional tunings are shown. Notice that these PFGs pairs project to similar regions of the FB, where their fibers partially overlap. This zero-degree phase shift establishes an approximate default mapping from PB glomeruli to EB columns. Related to Figure 30A.
