Values are Pearson coefficients of correlation between activity to 40% ethanol and tastants for 25 Wistar rat (W) and 42 alcohol-preferring rat (P) neurons tested with all stimuli.
*
Correlation for an ethanol-stimulus pair that is significantly greater in W neurons compared with P cells (P < 0.05). Stimuli are abbreviated as in Table 1.
