Hello, may you respond to the questions on the image? Question Prompt: Use what you know about the neural basis of Tritonia diomedia swimming behavior to indicate what would happen in each of the cases shown below. Assume in each case that you are to predict the effect of the stated manipulation (shown in the left-most column): Following each manipulation, (1) the animal is touched by a Pycnopodia helianthoides, the sea star predator; (2) activity of the various cells of the nervous system is recorded, and (3) the behavior of the slug is described. The list of possible answers appears below the chart. Note that the choices in the list at the bottom may need to be used once, multiple times, or never. If you don't see an answer on the list that you think is perfect, choose the one that is closest to what you think would happen. Also, a few cells will require more than one letter for a complete answer. The first row is filled in for you as an example of how to do this. Blacked out cells do not require an answer. Behavioral outcome Answer Strings (do not edit) Manipulation Effect on DSI Effect on C2 Effect on VSI Effect on DFN Effect on VFN Prevent DSIs from firing action potentials Prevent the C2s from firing action potentials Prevent the VSIs from firing action potentials Disconnect sensory receptors from the DRIs Paralyze both dorsal and ventral flexion muscles Prevent "ramp depolarization" from occurring in the DSIs B B B B F,G X;B;B;B;B;F,G AX;z WHEN FINISHED, COPY THIS: FG,X; 01i' A: Fires normal burst of action potentials B: Will not fire action potential burst C: Normal dorsal flexion D: Weak dorsal flexion E: Persistent dorsal flexion (goes on for a long time) F: No dorsal flexions G: No ventral flexions H: Slow burst (action potentials in burst relatively far apart) I: Very long duration burst of action potentials (may never stop)
