Subcutaneous injections of pentylenetetrazol (25 mg/kg) reliably increased the rate of nictitating membrane acquisition and enhanced a respiration rate discrimination between stimuli, while leaving rate of heart rate conditioning and discrimination formation unaffected. These effects were response and dosage dependent, with the greatest enhancement of performance occurring at dosages just under the convulsion threshold. The data suggest that pentylenetetrazol enhanced performance in the nictitating membrane response system by increasing the probability that Ss would move from an inactive to an active response state.
