Baseline measures in cholecystokinin B receptor (CCKBR) knockout mice. (a) CCKBR knockout mice exhibit similar levels of shock reactivity compared with wild-type littermates (b) CCKBR knockout mice do not weigh significantly different from wild-type littermates at 9 weeks of age. (c) There is no significant effect of genotype on time spent in the center of an open field chamber. (d) In addition, there is no effect of genotype on amount of time on the open arms of an elevated plus maze.
