Experimental protocol

Experimental day 1 2-6 7-9 10
Treatment Saline 2.5mg/kg Washout Saline
2.5mg/kg 2.5mg/kg

On experimental day 1 (ED1), neuronal recordings were performed after saline injection (baseline) for 30 minutes and continued for 90 minutes following 2.5mg/kg injection of MPD. Rats on ED2-6 were injected once a day in the morning (8 am) with 2.5mg/kg MPD. ED7 through ED9 were washout days (drug abstinence). Neuronal recordings resumed on ED10 after saline (baseline) and 2.5mg/kg MPD. On ED10 rats were treated identical as in ED1.
