Supplementary Figure 3: Tuning-width changes with preferred-stimulus post-conditioning, but not pre-conditioning.

From: Fear generalization in the primate amygdala

Supplementary Figure 3

a. Change in tuning width (width in post- minus pre-conditioning, mean±SEM) as a function of PS distance from CS (p=0.03, F=2.96, ANOVA). This suggests that neurons generally had wide tuning pre-conditioning and narrowed/widened their tuning with direct relationship to the distance of their post-conditioning PS from the CS.

b. The same analysis using PS from pre-conditioning showed no relationship (p=0.92 F=0.16 ANOVA).

c. Tuning width during post-conditioning generalization as a function of the PS in the pre-conditioning habituation (phase/tone/interaction p=0.25/0.76/0.59 F=1.33/0.39/0.63, 2-way ANOVA).

d. Same as in Fig.2e, but with width of tuning from pre-conditioning habituation (r=0.17, p=0.95, Pearson).
