Long-Term Effects Of 3,4- Methylenedioxymethamphetamine (Mdma) On Serotonergic And Dopaminergic Functioning, Jodi Lynn Kohutek Jan 2003

Long-Term Effects Of 3,4- Methylenedioxymethamphetamine (Mdma) On Serotonergic And Dopaminergic Functioning, Jodi Lynn Kohutek

Theses Digitization Project

Methylenedioxymethamphetamine (MDMA) popularly known as "Ecstasy" continues to gain popularity as a recreational drug that has been shown to increase serotonin and dopamine levels. The present study has demonstrated that repeated exposure to MDMA produces long-term damage to serotonergic and dopaminergic neurons in various regions of the rat brain.


The Effects Of Lesions To The Superior Colliculus And Ventromedial Thalamus On [Kappa]-Opioid-Mediated Locomotor Activity In The Preweanling Rat, Arturo Rubin Zavala Jan 2003

The Effects Of Lesions To The Superior Colliculus And Ventromedial Thalamus On [Kappa]-Opioid-Mediated Locomotor Activity In The Preweanling Rat, Arturo Rubin Zavala

Theses Digitization Project

The purpose of this thesis was to determine the neuronal circuitry mediating U50,488-induced locomotion in preweanling rats. To this end, preweanling rats received bilateral electrolytic lesions of the ventromedial thalamus or superior colliculus and, two days later, the same rats received a challenge injection of U50,488. It was predicted that bilateral lesions of the ventromedial thalamus or superior colliculus would attenuate the U50,488-induced locomotor activity of 18-day-old rats.


Induction And Expression Of Cocaine-Induced Behavioral Sensitization: Modulation By A Partial D₂-Like Agonist, Janet Marie Sibole Jan 2003

Induction And Expression Of Cocaine-Induced Behavioral Sensitization: Modulation By A Partial D₂-Like Agonist, Janet Marie Sibole

Theses Digitization Project

The purpose of this study was to investigate whether a partial D₂-like dopamine agonist (i.e. terguride) would block the induction or expression of cocaine-induced behavioral sensitization in pre-weanling rats. The ability of terguride to induce behavioral sensitization was also examined, as partial D₂-like agonists have agonistic actions in cases of low dopaminergic tone.
