Panel a: The mean (+SEM) ratio of active to inactive nosepokes made by groups during long access sessions. All groups discriminated between the active and inactive ports. Panels b–d show how self-administration behavior was distributed within the last 6 LgA sessions. Panel b: Mean (±SEM) cumulative infusions and total dose of cocaine self-administered by rats receiving cocaine over 5, 45, 90 sec during 6 hr LgA sessions. Panel c: Infusions during LgA session 14 in the same 3 representative rats as shown in Fig 3.3c. Panel d: The mean (±SEM) rate of self-administration (infusions/min) within LgA sessions.
