Cut L5 Ventral root Cut L5 spinal nerve Cut L5 dorsal root Spinal cord injury at the L5 level 2. You place a recording electrode into a Group Ia afferent and a separate recording electrode into a Group Ib afferent from the biceps muscle. You also place a length transducer and a force transducer on the muscle. Draw what you would expect to record from all of your recording devices at rest for 5 s, during a twitch contraction, and then 5 s after the contraction. Be sure to label all axes of your recordings. 3. A mouse you just discovered has either ALS or myasthenia gravis. Assuming that you can do invasive testing on this mouse, describe how you would figure out which disease the mouse has. You must use some electrophysiological recording in your test. Be specific about what exactly you are doing and why it will help you determine which disease the mouse has.
