Video 11. PFL2 phase shift.
Similar to Videos 6–7, this video highlights the 180° phase shift of the PFL2 population. The video begins by showing morphological renderings of an EPG neuron that contacts a PFL2 neuron in the PB. Notice that the PFL2 neuron, shown in blue, has processes in both R4 and R5. Next, the video shows the synaptic connection from the PFL2 neuron onto a DN in the LAL, and then briefly highlights an EPG to PFL2 connection in the left PB. At this point, notice that the PFL2 neurons innervating R5 and L5 (blue and gold), which share similar directional tuning, project to the lateral border of the FB, ~180° away from their PB regions. Lastly, the video shows individual morphological renderings of all PFL2 neuron before showing the population as whole. Related to Figure 39A.
