Table 7. Flavor selectivity in cue-selective neurons recorded in lesion vs. sham rats, statistics.

Listed are the results of a mixed ANOVA on flavor-selectivity indices across cue-selective neurons in both groups, with factors group (sham or lesion), time (early or late in blocks), and direction (preferred or anti-preferred).

		Planned comparisons (each tests whether indices are significantly shifted from zero):
	time X direction X group	lesion: preferred direction		lesion: anti-preferred direction		absolute value of indices
		early in blocks	late in blocks	early in blocks	late in blocks	late in blocks, preferred vs. anti- preferred @ lesion	late in blocks, (preferred vs. anti-preferred) X (sham vs. lesion)
F	0.0	1.7	0.3	0.4	1.6	17.0	20.8
df	1,90	1,90	1,90	1,90	1,90	1,90	1,90
p	0.88	0.19	0.57	0.54	0.21	<0.0001	<0.0001

In addition to the results in the table, there were no effects of group: main effect, F_1,90=0.06, p=0.81; group X time, F_1,90=0.62, p=0.43; group X direction, F_1,90=1.3, p=0.26. In the last two columns, the magnitude of flavor indices (absolute value) late in the block was tested, demonstrating that neurons in the lesion group, like shams, had significantly larger indices in the preferred direction, and also that lesions enhanced the degree to which neurons encode flavor, compared to shams. df = degrees of freedom.
