Also conspicuous is the near absence of responses for the head/neck representation in the medial zone for both controls and Alectinib ic50 amputees. An ANOVA was performed on the total area of CN, and no significant differences in total size of CN (P≥0.105) or total size of the central zone (P≥0.32) were observed between control and deafferented

animals. However, significant group differences in total area were found in the total area of the lateral zone (P≤0.047) and near significant difference for the medial zone (P≤0.06), although no significant differences were found between groups in post hoc comparisons. The total areas of the shoulder, head/neck, and body (back, side, abdomen, chest) representations in each zone were measured in control and amputees over post-deafferented weeks. The data are plotted in a scatter plot format and analyzed using regression analysis and Pearson Product-Moment correlation and presented in Fig. 8. A regression line was plotted for each group. Medial zone –

no significant differences in the total area of the shoulder and head/neck representations in the medial zone were found over post-deafferentation weeks. However, the body representation did show a significant difference and positive correlation (P≤0.0001, t-ratio=4.49, r=0.60) over post-deafferentation weeks. Central zone – no significant differences in the total area of the body, shoulder, and head/neck representations in the central zone were observed over post-deafferentation weeks. Lateral zone – no significant

In contrast, significant differences and positive correlations were observed for the body (P≤0.003, t-ratio=3.24, r=0.49) and head/neck (P≤0.01, t-ratio=2.98, r=0.45) in the lateral zone over post-deafferentation weeks. The total averaged areas of the shoulder, body, and head/neck were calculated as a percentage of the total averaged area of each zone and these results are presented in Fig. 9. Regression analysis and Spearman Rank correlation were used to analyze the data. While these results are similar to the total areas of the body-part representations presented above, the averaged data nonetheless provide a useful day-by-day overview over post-deafferentation weeks. Medial zone – the percent body representation within the medial zone had a significant increase (P≤0.0001, t-ratio=5.74) and positive correlation (r=0.67) over post-deafferentation weeks that reached a 90% occupancy during deafferent weeks 9–12. The shoulder representation occupied 14% of the medial zone in controls and increased to approximately 19% during 1-WD through 4-WD. In 5-WD, 51% of the medial zone was occupied by the shoulder, and subsequently dropped back to 24% in 6–8-WD and jumped to 33% during 9–12-WD. These changes were not significant. Rarely were inputs from the head/neck found in the medial zone.
