^*Grid+ and Grid− groups combined

^#except for Habituation and Saline:Trial 1 where n = 23

d= p<.0001, c= p<.001, b= p<.01, a= p<.05, significant difference from habituation session (Saline) or Ethanol Trial 1 (Ethanol)

z= p<.0001, y= p<.001, x= p<.01, w= p<.05, significant difference from Saline on the same trial

^**p values based on within strain comparison between Ethanol-Saline differences on Trial 4 vs Trial 1
