• Anorectic estrogen mimics leptin's effect on the rewiring of melanocortin cells and Stat3 signaling in obese animals.

  Metabolic hormones, such as leptin, alter the input organization of hypothalamic circuits, resulting in increased pro-opiomelanocortin (POMC) tone, fo…

• Remodeling of hippocampal spine synapses in the rat learned helplessness model of depression.

  BACKGROUND: Although it has been postulated for many years that depression is associated with loss of synapses, primarily in the hippocampus, and that…

• Effects of androgens and estradiol on spine synapse formation in the prefrontal cortex of normal and testicular feminization mutant male rats.

  Recent studies suggest that, in female monkeys and rats, estrogens elicit dendritic spine synapse formation in the prefrontal cortex, an area that, si…

• Dehydroepiandrosterone increases hippocampal spine synapse density in ovariectomized female rats.

  This study tests the hypothesis that dehydroepiandrosterone (DHEA) stimulates formation of hippocampal CA1 spine synapses in ovariectomized rats. Subc…
