Available in PDF, EPUB and Kindle. Book excerpt: The present experiment examined the effects of environmental enrichment on behavioral measures of locomotor activity, stress, and health in rats. Six measures (i.e., Open Field, Elevated Plus Maze, Light/Dark Box, Plasma Corticosterone, Food Consumption, and Body Weight) were used to examine the effects of enrichment and stress on 48 male, adolescent Sprague-Dawley rats that were placed in an enriched or non-enriched environment for a total of 24 days. Compared with rats housed in non-enriched environments, rats that were housed in enriched environments showed the following: (1) decreased activity and increased habituation in a novel environment; (2) ate less food and had less body weight gain (6% on average). The results regarding stress responses were inconclusive. These findings and future research investigating the effect of environmental enrichment to slow the rate of weight gain are discussed.

This book was released on 2006 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Housing animals in an enriched environment has a substantial effect upon neuroanatomy, behavior, and cognition. Rats housed in enriched conditions (EC) and trained to perform a prefrontal cortex (PFC) dependent, forced-choice delayed-alternation task on a T-maze showed superior performance to impoverished condition (IC) housed rats. Expression of Group I (mGluR1 and 5) and Group II (mGluR2/3) proteins within the PFC of EC, standard/socially housed (SC), and IC subjects was assessed by immunoblotting for dorsal PFC (dPFC), ventral PFC (vPFC), and control areas (striatum, hippocampus, parietal cortex). A significant effect of housing was observed for total mGluR5 protein (p

Download or read book The Catecholaminergic Innervation of the Rat Amygdala written by Esther Asan and published by Springer. This book was released on 1998-03-18 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental evidence indicates that catecholamines are able to modulate information processing in the amygdaloid complex. The dense catecholaminergic innervation of the amygdala may thus exert significant influence upon its well-documented functions in emotion, attention, learning and memory. Dysfunctions of the systems have been suggested to be involved in the etiology of neuropsychiatric disorders including senile dementia, Parkinson's disease and schizophrenia. To further insight into neural mechanisms of the innervation, the present study provides a detailed documentation of ultrastructural and neurochemical characteristics of dopanminergic, noradrinergic and adrenergic afferent fibers and of their target structures in central, basal and intercalated amygdaloid nuclei. A high degree of heterogeneitiy is observed between the nuclei concerning the different catecholaminergic innervation patterns and the peptide content of individual catecholaminergic fibers, as well as concerning the neurotransmitter/-modulator and receptor expression of possible amygdaloid target neurons. The results are discussed with regard to previously documented properties of the nuclei.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Individuals suffering from depression primarily rely on pharmacological interventions to alleviate the incapacitating symptoms of the disorder. In addition to genetic differences underlying the etiology of depression, environmental factors play a key role as well. For example, environmental enrichment results in various neurotransmitter alterations, significantly affecting serotonin. To test the efficacy of novel antidepressant drugs in the preclinical laboratory setting, researchers commonly implement the forced swim test (FST) for rats or mice. However, the effect of environmental enrichment on the expression of depressive-like states in the FST is unclear, and it is unknown whether environmental enrichment or social isolation can alter the efficacy of the commonly prescribed antidepressant drug, fluoxetine. In the present study, locomotor activity and FST performance were measured after 30 days of rearing in enriched (EC), standard (SC), and isolated (IC) conditions. Results showed that regardless of the significant effect of fluoxetine on locomotor activity in EC, SC, and IC rats, fluoxetine failed to increase swimming and decrease immobility in all three environmental conditions, with enriched-fluoxetine rats displaying significantly less swimming behavior in the FST than enriched rats receiving vehicle control injections. These results suggest that differential rearing, specifically environmental enrichment, can alter the efficacy of antidepressants and may suggest that enrichment reverses the effects of fluoxetine.
