AZD@ induced dose-dependent smaller-than-lorazepam effects on saccadic peak velocity ( SPV ) ( AZD@ , @ mg vs. AZD@ , @ mg vs. lorazepam -LSB- deg/s -RSB- : -@ vs. -@ vs. -@ , P < @ ) , whereas the impacts on adaptive-tracking , body-sway , smooth-pursuit , and the one-card-learning tests were significant but much smaller than lorazepam .
