The effect of preweaning infantile food deprivation on hoarding in adult rats
… to each daily hoarding trial. Though laboratory rats will hoard food without being food deprived (Bindra, 1948) deprivation prior to trials facilitates the amount of hoarding (Morgan, Stellar & Johnson, 1943; Guerra, 1970).</p>

Potential for change: Characterizing synaptic plasticity following visual discrimination learning in adult rats.
… in order to describe synaptic plasticity in the adult rat visual system after learning a simple visual discrimination task. Initially, a novel method is described providing a simple and noninvasive means to restrict visual input. Using a harness and face-mask for monocular occlusion, rats were …

The Effect of Us-Preexposure On Meth-Induced Cta In Periadolescent and Young Adult Rats
… about the aversive effects of abused drugs than adults. Therefore, the present study utilized the conditioned taste aversion procedure (CTA) to investigate the aversive effects of the highly addictive drug methamphetamine (METH). Specifically, the experiment investigated the impact of …

The effect of exercise on spatial learning and hippocampal proteins in maternally separated adult rats
… in the hippocampus of non-separated-exercised rats. In the current study, the same MS technique and three-week voluntary exercise regimen were tested to determine their effect on spatial learning in young adult Sprague-Dawley (SD) rats. A total of 144 rats were either maternally separated from …

Ventral Tegmental Area Neuronal Responses to Methylphenidate Correlated to Behavioral Responses of Adolescent and Adult Rats
… hundred and thirteen adolescent animals and 51 adult rats were divided into 4 groups: saline, 0.6, 2.5, and 10.0 mg/kg MPD and had their neuronal and behavioral activity recorded concomitantly following one of the chosen MPD doses. In order to determine if there are neuronal differences between …

The persistance of the effects of certain aspects of infantile experience on the behaviour of adult rats
Since Hunt's (1941) claim that he had introduced · a new field into the laboratory study of the animal - its 1• life history - there has been a spate of work in which the effects of many different kinds of variation have been studied. Though one may question the validity of Hunt's claim (see, for …

The effects of restricted movement and forced exercise on protein metabolism and body composition of adult rats
… on protein metabolism and body composition of adult rats. Half of the animals were restricted in movement and half of each group were forced to exercise by swimming for ten days. The study entailed a six day adjustment period, a four day balance study, and a ten day exercise period followed by …

Chronic intermittent ethanol treatment yields persistent increases in anxiety and receptor subunit changes in adolescent and adult rats.
… increased prevalence of consumption during young adulthood compared to that of abstaining adolescents, and increased risk for development of future alcohol use disorders. In the adult, tolerance and dependence are marked by attenuated function of GABAA receptors and increased function of NMDA …

The Effect of Long Term High Protein Induced Calciuria on Calcium Metabolism and Bone Status in Adult Rats
… during high protein consumption in humans and rats has been implicated as a factor in the etiology of osteoporosis. The source of increased urinary calcium is controversial and has been attributed to either increased absorption, increased bone resorption or both. A 20 week study was conducted …

Extended Treatment Window Exists for Improving Sensorimotor Recovery Using Anti-Nogo a Immunotherapy in Adult Rats with Chronic Stroke Deficits
… treatment results in sensorimotor recovery in adult and aged rats. This therapy has been shown to be efficacious when applied immediately, 24 hours, and 1 week post-stroke in rats with mild to moderate sensorimotor deficits. In addition, recent results suggest that administration of anti-Nogo-A …

EFFECTS OF REPEATED ARIPIPRAZOLE TREATMENT ON THE cAMP AND AKT PATHWAYS IN THE DORSAL STRIATUM OF PREADOLESCENT AND ADULT RATS
… has fewer side effects, making it tolerable for adults and children. Extrapyramidal effects (e.g. Parkinsonism, dystonia, and akathisia) are among the most problematic side effects produced by antipsychotic compounds, which likely result from an excess of D2-like receptors in the dorsal striatum. …
