d′ values (mean ± SEM) for 45 dph core and shell for BOS-responsive neurons

d′ comparison	BOS-responsive 45 dph neurons
	Core	Shell
BOS–REV	0.41 ± 0.05	0.58 ± 0.06*
BOS–TUT	0.27 ± 0.04	0.49 ± 0.07**
BOS–CON	0.39 ± 0.06	0.62 ± 0.10*
BOS–AMC	0.32 ± 0.05	0.50 ± 0.08

Core, n = 65 versus REV, n = 55 versus TUT, n = 38 versus CON and AMC; shell, n = 36 versus REV, n = 32 versus TUT, n = 16 versus CON and AMC.

*p < 0.05 and **p < 0.01 for significant differences between mean d′ values of core and shell. We used ΔSR scores in preference to d′ scores for methodological reasons (see Materials and Methods). However, both measures showed good agreement in terms of assessing differences in selectivity between shell and core neurons: BOS-selectivity of shell neurons was higher than that in core neurons.
