Table 5. Flavor selectivity in cue-selective neurons recorded in sham rats, statistics.

Listed are the results of a within-subjects ANOVA on flavor-selectivity indices across cue-selective neurons, with factors time (early or late in blocks) and direction (preferred or anti-preferred). These results show that neurons do not in general prefer chocolate or vanilla in any condition. For the last column, the magnitude of the indices (absolute value) was compared between the preferred and anti-preferred directions late in blocks.

		Planned comparisons (each tests whether indices are significantly shifted from zero):
		preferred direction		anti-preferred direction		absolute value of indices late in blocks, preferred vs. anti-preferred
	time X direction	early in blocks	late in blocks	early in blocks	late in blocks
F	0.7	3.4	1.5	1.4	0.4	16.6
df	1,65	1,65	1,65	1,65	1,65	1,65
p	0.41	0.07	0.22	0.23	0.55	<0.001

This significant result demonstrates that neurons show greater selectivity to flavor on the preferred side. df = degrees of freedom.
