Effects of early midlife ovarian removal on sleep: Polysomnography-measured cortical arousal, homeostatic drive, and spindle characteristics

Author(s): Brown A; Gervais NJ; Gravelsins L; O' Byrne J; Calvo N; Ramana S; Shao Z; Bernardini M; Jacobson M; Rajah MN; Einstein G;

Bilateral salpingo-oophorectomy (BSO; removal of ovaries and fallopian tubes) prior to age 48 is associated with elevated risk for both Alzheimer's disease (AD) and sleep disorders such as insomnia and sleep apnea. In early midlife, individuals with BSO show reduced hippocampal volume, functi ...

Iron Deposition and Distribution Across the Hippocampus Is Associated with Pattern Separation and Pattern Completion in Older Adults at Risk for Alzheimer's Disease

Author(s): Zhou J; Wearn A; Huck J; Hughes C; Baracchini G; Tremblay-Mercier J; Poirier J; Villeneuve S; Tardif CL; Chakravarty MM; Daugherty AM; Gauthier CJ; Turner GR; Spreng RN;

Elevated iron deposition in the brain has been observed in older adult humans and persons with Alzheimer's disease (AD), and has been associated with lower cognitive performance. We investigated the impact of iron deposition, and its topographical distribution across hippocampal subfields and ...

Combined effects of the contraceptive hormones, ethinyl estradiol and levonorgestrel, on the use of place and response memory in gonadally-intact female rats

Author(s): Lacasse JM; Boulos V; Fisher C; Hamilton S; Heron M; Mac Cionnaith CE; Peronace V; Tito N; Brake WG;

During maze navigation rats can rely on hippocampus-mediated place memory or striatum-mediated response memory. Ovarian hormones bias whether females use place or response memory to reach a reward. Here, we investigated the impact of the contraceptive hormones, ethinyl estradiol (EE) and levonorg ...

The role of progesterone in memory bias during spatial navigation in females

Author(s): Eamonn L Gomez-Perales

Rats can use several memory systems to navigate a maze toward a reward. Two of these are place memory and response memory and female rats can be biased to predominantly use one over another. Both progesterone and estrogens have been shown to alter memory bias. Although the effects of estrogens have been well documented, the effects of progesterone remain ...

Progesterone rapidly alters the use of place and response memory during spatial navigation in female rats

Author(s): Lacasse JM; Patel S; Bailey A; Peronace V; Brake WG;

17ß-Estradiol (E2) and progesterone (P) influence place and response memory in female rats in spatial navigation tasks. Use of these memory systems is associated with the hippocampus and the dorsal striatum, respectively. Injections of E2 result in a well-established bias to use place memory, while much less is understood about the role of P. A total of 1 ...
