Opiates inhibit neurogenesis in the adult rat hippocampus.
Recent work implicates regulation of neurogenesis as a form of plasticity in the adult rat hippocampus. Given the known effects of opiates such as morphine and heroin on hippocampal function, we examined opiate regulation of neurogenesis in this brain region. Chronic administration of morphine decreased neurogenesis by 42% in the adult rat hippocampal granule cell layer. A similar effect was se...
متن کاملNeurogenesis in Adult Hippocampus
Hippocampus as a whole has the shape of a curved tube including CA1-CA4 regions with a single layer of densely packed pyramidal neurons which curl into a tight “U” shape. One edge of the “U”, field CA4, is embedded into a backward facing strongly flexed V-shaped cortex, the dentate gyrus (DG) which comprises molecular, granular, subgranular cell layers and poly-morph layer called hilus (Figure ...
متن کاملNeurogenesis by progenitor cells in the ischemic adult rat hippocampus.
BACKGROUND AND PURPOSE Recently, there has been great interest in adult neurogenesis. We investigated whether transient forebrain ischemia could influence the proliferation of neuronal progenitor in the subgranular zone (SGZ) of the rat hippocampus and whether aging could influence the neurogenesis after ischemia. METHODS Male Wistar rats were subjected to 4-vessel occlusion model. We used a ...
متن کاملChronic antidepressant treatment increases neurogenesis in adult rat hippocampus.
Recent studies suggest that stress-induced atrophy and loss of hippocampal neurons may contribute to the pathophysiology of depression. The aim of this study was to investigate the effect of antidepressants on hippocampal neurogenesis in the adult rat, using the thymidine analog bromodeoxyuridine (BrdU) as a marker for dividing cells. Our studies demonstrate that chronic antidepressant treatmen...
متن کاملBinge ethanol exposure decreases neurogenesis in adult rat hippocampus.
Alcoholism is associated with cognitive deficits and loss of brain mass. Recent studies have indicated that neural progenitor cells proliferate throughout life forming neurons, astrocytes, and oligodendrocytes. The dentate gyrus is one neurogenic region of the adult brain containing neural progenitor cells. To determine if binge ethanol (EtOH) exposure alters neural progenitor cell proliferatio...
