Calculate the conduction velocities for the ipsilateral | Homework Helpers

(1) Using Figure 1 and 9C in the paper by Carr & Konishi (1990), compute the conduction velocities for the ipsilateral and contralateral axons from the nucleus magnocellularis (NM) within the nucleus laminaris (NL). Assume that the NM axons travel in a straight line, perpendicular to the dorsomedial surface of NL. Show your work and explain your reasoning in 100 words or less.

Figure 1 shows both the cochlear nuclei (NA, NM) and the nucleus laminaris (NL).

Figure 9C shows a plot of latencies from 5 penetrations through the nucleus laminaris. Latencies of isilateral (i) and contralateral (c) axons measured at the dorsal border of the nucleus are in columns marked iD and cD, respecively, and latencies measured at the ventral border are marked iV and cV. The position of the mean of each column are indicated by a bar. ( the mean latencies: iD = 2.8 msec, iV=3.0 msec, cV= 2.9msec, cD=3.1 msec)
