Persistence Of One-Trial Cocaine-Induced Behavioral Sensitization And Conditioned Activity In Preweanling Rats, Anthony Michael Cortez
Persistence Of One-Trial Cocaine-Induced Behavioral Sensitization And Conditioned Activity In Preweanling Rats, Anthony Michael Cortez
Theses Digitization Project
The purpose of this thesis was to determine the persistence of one-shot context-specific and context-independent behavioral sensitization by administering a single pretreatment injection of cocaine or saline in either the home cage or a novel test chamber on PD 19 or PD 79. In order to examine the persistence of conditioned activity, adult rats were given an injection of saline after 1, 3, or 5 abstinence days. Preweanling rats were given an injection of saline after only 1 abstinence day.
Role Of Dorsostriatal D1 And D2 Receptors In Modulating The Kappa Opioid-Mediated Locomotor Activity Of Preweanling Rats: Importance Of Synergistic Activation, Sergios Charntikov
Role Of Dorsostriatal D1 And D2 Receptors In Modulating The Kappa Opioid-Mediated Locomotor Activity Of Preweanling Rats: Importance Of Synergistic Activation, Sergios Charntikov
Theses Digitization Project
Infusions of the nonselective dopamine agonist R( - ) propylnorapomorphine (NPA) into the dorsal striatum of preweanling rats atteuates kappa opioid-mediated locomotor activity. The purpose of this thesis was to ascertain which dopamine receptor subtype (D1 or D2) is responsible for this effect. It was hypothsized that a) D1, but not D2, receptors in the dorsal striatum underlie NPA's ability to attenuate the kappa opioid-mediated locomotor activity of preweanling rats, and b) microinjectng SKF38393 (a D1 agonist), and not quinpirole (a D2 agonist), would attenuate kappa opioid-mediated locomotion.

The goal of this experiment was to examine the pattern of ACh release in mPFC and HPC during performance in trace and delay appetitive conditioning.
