Contraction of stimulated wild-type FDB muscle 3 d after sciatic nerve lesion. QuickTime video of wild-type isolated nerve muscle preparations imaged via a dissecting microscope showing tetanic contractions of the FDB muscle in response to supramaximal 20-Hz stimulation of the tibial nerve (see Materials and methods). The video was captured in real time (input, 12 frames per second; key frame rate, 24 frames per second) using a Coolpix 4500 digital camera via an ocular adaptor attached to the dissecting microscope. The video was exported directly from the camera in QuickTime format to a Macintosh G4 computer and edited for length using only QuickTime 7.5 software. Neither the frame rate nor the color maps were altered in the final cut.
