Results of least-squares regression applied to responses by 22 S-type neurons to 0.1, 0.17, 0.31, and 0.56 M sucrose at each temperature

°C	Slope [95% CI lower, 95% CI upper]	Intercept	r2	Group
18	1.44 [1.18, 1.70]	2.25	0.61	a
22	0.94 [0.74, 1.15]	2.42	0.52	b
30	0.39 [0.25, 0.54]	2.38	0.26	c
37	0.50 [0.31, 0.68]	2.29	0.26	c

Values are results of least-squares regression applied to responses by 22 S-type neurons to 0.1, 0.17, 0.31, and 0.56 M sucrose at each temperature (Fig. 3). Calculations operated on the logarithm of the spiking response and the logarithm of concentration. All regression slopes were significantly greater than 0 (P < 0.001). The Group column indicates whether there was separation, denoted by different characters, between the 95% confidence intervals (95% CIs) for 2 slopes.
