Cognition And The Brain Of Brood Parasitic Cowbirds., David F Sherry, Mélanie F Guigueno Mar 2019

Cognition And The Brain Of Brood Parasitic Cowbirds., David F Sherry, Mélanie F Guigueno

Psychology Publications

Cowbirds are brood parasites. Females lay their eggs in the nests of other species, which then incubate the cowbird eggs and raise the young cowbirds. Finding and returning to heterospecific nests presents cowbirds with several cognitive challenges. In some species, such as brown-headed cowbirds (Molothrus ater), females but not males search for and remember the locations of potential host nests. We describe recent research on sex differences in cognition and the hippocampus associated with this sex difference in search for host nests. Female brown-headed cowbirds perform better than males on some, but not all, tests of spatial memory and females …

The Role Of Er-Alpha And The Ovaries In The Enduring Altered Behavioral Response To Pubertal Immune Stress, Bethany Rappleyea Jan 2014

The Role Of Er-Alpha And The Ovaries In The Enduring Altered Behavioral Response To Pubertal Immune Stress, Bethany Rappleyea

Masters Theses 1911 - February 2014

Peripubertal immune stress alters adult responsiveness to estradiol (E2) and progesterone (P). When female mice are injected with the bacterial endotoxin lipopolysaccharide (LPS) at six weeks of age, or during pubertal development, they display a decrease in response to ovarian hormones. In contrast, females ovariectomized prior to peripubertal immune stress display typical levels of sexual behavior following sequential injections of E2 and P in adulthood. Additionally, intact females exposed to peripubertal immune stress display a decrease in estrogen receptor alpha (ER-α)-immunoreactive (ir) cells in the medial preoptic area (MPOA) and ventromedial nucleus of the hypothalamus (VMH) in …
