TrkB-GFP movements upon cAMP stimulation within axon terminals of LV-mCh Smn−/−;SMN2 motoneurons. Time-laps videos were recorded from DIV7 Smn−/−;SMN2 motoneurons co-transduced with LV-mCh and LV-TrkB-GFP (gray) during a 30 min 100 µM 8-CPT-cAMP stimulation using an epifluorescence microscope acquiring images at a 2.5 s interval over a time period of 10 min. TrkB-GFP movements (gray) are shown at a display rate of 7 frames per second.
