Journal ArticleDOI
Tamoxifen improves cholinergically modulated cognitive performance in postmenopausal women.
Paul A. Newhouse,Kimberly Albert,Robert S. Astur,Julia V. Johnson,Magdalena R. Naylor,Julie A. Dumas +5 more
TL;DR: Evidence is provided that TMX may act as an estrogen-like agonist to enhance cholinergic system activity and hippocampally mediated learning to affect cognitive performance in older women using a model of anticholinergic drug-induced cognitive dysfunction.
Journal ArticleDOI
Estrogen enhances hippocampal gray-matter volume in young and older postmenopausal women: a prospective dose-response study.
Kimberly Albert,Jessica Hiscox,Brian D. Boyd,Julie A. Dumas,Warren D. Taylor,Paul A. Newhouse,Paul A. Newhouse +6 more
TL;DR: Findings accord with previous animal studies and provide evidence of estrogen effects on hippocampal morphology that may represent a neurobiological mechanism for estrogen effect on cognition in postmenopausal women.
Journal ArticleDOI
Dietary saturated fat and monounsaturated fat have reversible effects on brain function and the secretion of pro-inflammatory cytokines in young women.
Julie A. Dumas,Janice Y. Bunn,Joshua P. Nickerson,Karen I. Crain,David B. Ebenstein,Emily K. Tarleton,Jenna Makarewicz,Matthew E. Poynter,Craig Lawrence Kien +8 more
TL;DR: The HPA diet resulted in increased brain activation in the basal ganglia compared to the HOA diet as well as increased secretion of pro-inflammatory cytokines, consistent with the hypothesis that lowering the dietary PA content via substitution with OA also could affect cognition.
Journal ArticleDOI
Estrogen treatment impairs cognitive performance after psychosocial stress and monoamine depletion in postmenopausal women.
Paul A. Newhouse,Julie A. Dumas,Heather Wilkins,Emily L. Coderre,Cynthia K. Sites,Magdalena R. Naylor,Chawki Benkelfat,Simon N. Young +7 more
TL;DR: The relationship between estrogen administration and cognitive/behavioral performance in postmenopausal women may be more complex than initially appreciated and that the effects of psychosocial stress may influence whether hormone effects are beneficial.
Journal ArticleDOI
The Stroop effect in kana and kanji scripts in native Japanese speakers: an fMRI study.
TL;DR: The results of the present study suggest that the Stroop task in Japanese kana and kanji elicits differential activation in brain regions involved in conflict detection and resolution for syllabic and logographic writing systems.
