Adolescent And Adult Nicotine Exposure On The Acquisition Of Methamphetamine Self-Administration And The Reinstatement Of Extinguished Methamphetamine-Seeking In Male Rats, Joseph Allan Pipkin
Adolescent And Adult Nicotine Exposure On The Acquisition Of Methamphetamine Self-Administration And The Reinstatement Of Extinguished Methamphetamine-Seeking In Male Rats, Joseph Allan Pipkin
Theses Digitization Project
This study sought to determine the individual and combined contribution of adolescent and adult nicotine exposure on METH self-administration and METH-seeking behavior in male rats. Nicotine is a commonly abused substance among adolescents and is believed to be a "gateway" to other drugs of abuse. In support of the gateway hypothesis, cigarette smoking during adolescence is related to increased methamphetamine (METH) use in adulthood.
Monoamine Modulation Of Separation-Induced Ultrasonic Vocalizations In Preweanling F344 And Sd Rats, Cynthia Elizabeth Britt
Monoamine Modulation Of Separation-Induced Ultrasonic Vocalizations In Preweanling F344 And Sd Rats, Cynthia Elizabeth Britt
Theses Digitization Project
The purpose of this study was to determine if Fischer 344 (F344) rats, a strain which naturally shows deficits in social communication during adolescence, could be used as a model of the social communication deficits observed in autism. Thus, the goal was to determine if F344 rats would also show fewer emissions of isolated-induced ultrasonic vocalizations (an early onset form of social interaction) as compared to SD rats. Subjects consisted of 142 F344 rat pups (67 male and 75 female). Subjects were treated according to the "Guide for the Care and Use of Mammals in Neuroscience and Behavioral Research" under …

Behavioral sensitization is defined as an increase in behavioral responding that occurs after repeated administration of a psychostimulant. Behavioral sensitization is an important component of the addiction process that is mediated by different brain regions. In this thesis, lidocaine was used to determine those brain areas mediating one-trial behavioral sensitization in preweanling rats.

Ontogeny Of One-Trial Behavioral Sensitization In Preweanling, Adolescent, And Adult Rats: Differential Effects Of Cocaine And Methamphetamine, Olga Olia Kozanian
Theses Digitization Project
The purpose of this thesis was to assess the ontogeny of cocaine- and methamphetamine-induced one-trial locomotor sensitization in preweanling, adolescent, and adult rats. Subjects were 336 male and female rats of Sprague-Dawley descent that were raised at California State University, San Bernardino (CSUSB).
Effects Of Chronic Paroxetine And Fluoxetine Treatment On Markers Of Suicidal Behavior In Adolescent Rats, Leslie Renee Horn
Effects Of Chronic Paroxetine And Fluoxetine Treatment On Markers Of Suicidal Behavior In Adolescent Rats, Leslie Renee Horn
Theses Digitization Project
Major depression is a common problem in adolescents. Unfortunately, one of the most effective antidepressants in adults, the selective serotonin reuptake inhibitor (SSRI) paroxetine, is not clinically effective in pediatric populations. There are many variables that increase the risk of suicide including genetic, social, psychological, and biological factors, making the evaluation of the effect of SSRIs on suicidal behavior difficult to assess in human adolescents. The goal of the present investigation was to compare the effects of paroxetine and fluoxetine in adolescent rats on markers associated with depression and suicidal behavior in humans.
Consequences Of Early Methylphenidate Exposure On Opioid System Functioning In Adult Rats, Matthew Scott Herbert
Consequences Of Early Methylphenidate Exposure On Opioid System Functioning In Adult Rats, Matthew Scott Herbert
Theses Digitization Project
Methylphenidate is the preferred treatment for attention-deficit hyperactivity disorder in preschool-aged children, even though few human studies have assessed the long-term consequences of early methyphenidate use. In rats, exposure to methylphenidate during a developmental period that approximates early childhood increases morphine-induced antinociception in adulthood. However, because morphine activates three distinct opioid receptors it is unknown which receptor is resonsible for this methylphenidate effect. The purpose of the present study was to assess the long-term effects of early methylphenidate exposure on DAMGO- and U50, 488-induced antinociception, a mu-opioid and kappa-opioid selective agonist.

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 Effects Of (Rs)-Mcpg On Amphetamine-Induced Sensitization In Neonatal Rats, Fiona Yeuk-Lun Choi
The Effects Of (Rs)-Mcpg On Amphetamine-Induced Sensitization In Neonatal Rats, Fiona Yeuk-Lun Choi
Theses Digitization Project
The purpose of the study was to investigate the role of metabotropic glutamate receptors (mGluR) in the ontogeny of amphetamine-induced behavioral sensitization. Eleven-day-old rat pups were given five daily bilateral infusions of the mGluR antagonist, (RS)-methyl-4-carboxyphenylglycine (MCPG) followed by a systemic injection of amphetamine and locomotor activity was measured. It was hypothesized that rats receving amphetamine pretreatment and an amphetamine challenge would exhibit a significant increase in activity, indicating short-term behavioral sensitization. As predicted, repeated amphetamine administration during the pretreatment phase produced progressively enhanced locomotor activity, indicating the development of behavioral sensitization. The effect of MCPG on locomotor activity appears …
Biconditional Discrimination Learning In Rats With 192 Igg-Saporin Lesions Of The Nucleus Basalis Magnocellularis, Michael Ryan Kitto
Biconditional Discrimination Learning In Rats With 192 Igg-Saporin Lesions Of The Nucleus Basalis Magnocellularis, Michael Ryan Kitto
Theses Digitization Project
The experiment tested the hypothesis that 192 IgG-saporin lesions of the nucleus basalis magnocellularis (NBM) in rats would impair performance in a biconditional visual discrimination task, which requires configural association learning. Experiment used 22 male Long-Evan rats (Harlan Sprague-Dawley). Behavioral testing was conducted in two identical T-mazes. Rats were randomly assigned to either a bilateral 192 IgG-saporin lesion group (n = 10) or to a control group (n = 12). Results support the hypothesis that NBM is critically involved in configural but not simple association learning and suggest that NBM may be involved more generally in cognitive flexibility.
Actions Of A Partial D2-Like Agonist During Low Or High Dopaminergic Tone: A Neurochemical Study Using Preweanling Rats, Shelly Taeko Yoshida
Actions Of A Partial D2-Like Agonist During Low Or High Dopaminergic Tone: A Neurochemical Study Using Preweanling Rats, Shelly Taeko Yoshida
Theses Digitization Project
The neurochemical effects of partial D2-like agonists (i.e., terguride) to alter striatal DOPA accumulation under high and low dopaminergic tone was examined in preweanling rats. The results indicate that terguride has agonist-like (quinpirole-like) effects under a low dopaminergic tone and antagonist-like (haloperidol-like) effects under a high dopaminergic tone during the preweanling period.

This study examined the effect of preweanling methyphenidate exposure on later drug reward. We examined the induction, extinction, and reinstatement of morphine induced conditioned place preference (CPP) in rats that received methylphenidate pretreatment during the preweanling period.
Cholinergic Basal Forebrain Involvement In The Acquisition Of Differential Reinforcement Of Low Rate Responding Tasks In Rats, Sean Ryan Corley
Cholinergic Basal Forebrain Involvement In The Acquisition Of Differential Reinforcement Of Low Rate Responding Tasks In Rats, Sean Ryan Corley
Theses Digitization Project
It was hypothesized that 192 IgG-saporin lesions of the basal forebrain cholinergic system (BFCS) would disrupt differential reinforcement of low rate (DRL) learning in an uncued DRL task, but would not impair acquisition and performance in the cued version of the task. Results suggest that BFCS lesions impair vigilance to the external cues despite continued practice in the cued DRL, whereas continuous attention to internally produced cues recovers with extended practice in the uncued DRL.
