Stressful experiences can affect hippocampal structure and function and can suppress new cell birth in the adult hippocampus in several species. Here we examine how repeated intermittent social defeat affects cell proliferation in the dentate gyrus (DG) in mice. Adult male CFW mice were subjected to 10 daily social defeat episodes, 3 defeat episodes within(More)
Marijuana is a widely abused illicit drug known to cause significant cognitive impairments. Marijuana has been hypothesized to target neurons in the hippocampus because of the abundance of cannabinoid receptors present in this structure. While there is no clear evidence of neuropathology in vivo, suppression of brain mitogenesis, and ultimately(More)
Hippocampal cell proliferation and concomitant motor activity were examined in adult male mice (C57BL/6J) across a 12:12h light-dark cycle. 5-Bromo-2'-deoxyuridine (BrdU) (200 mg/kg, i.p.) was administered at six equally spaced time points across 24h. A significant change in cell proliferation was found in the hilus (light phase>dark phase), but not in the(More)
Sleep loss is known to potently suppress adult hippocampal cell proliferation and neurogenesis. Whether sleep suppression following acute administration of stimulant drugs also decreases hippocampal cell proliferation is not known. The present study examined the effect of three mechanistically distinct stimulants (caffeine, methamphetamine and modafinil) on(More)
