Runway speeds over 10 sessions of PSA. Rats were trained from PND 22–25. (A) Saline control rats showing patterning from session 7. (B) Rats neonatally treated with 0.25 mg/kg of MK-801 unable to pattern and showing significantly lower overall running speed. (C) Rats neonatally treated with the less active isomer of MK-801 showing impaired patterning compared with saline control. (D) Rats neonatally treated with 0.025 mg/kg of MK-801 having significantly lower running speeds compared with saline control. These results did not differ significantly from the isomer condition.
