The effect of 0.02 mg/kg SCH 23390 (SCH) on the disruptive effects of 1 mg/kg amphetamine (Amph) on latent inhibition. Mean suppression ratios to the light conditioned stimulus (CS, ±s.e.m.) for non-pre-exposed (control, white bars) and pre-exposed (PE, light grey bars) rats that had previously been treated with saline, Amph, SCH or Amph+SCH. * Indicates significant difference from similarly treated PE group (p<0.05).
