Increased working memory-related brain activity in middle-aged women with cognitive complaintsJulie A Dumas
Clinical Neuroscience Research Unit, Department of Psychiatry, University of Vermont College of Medicine, Burlington, VT 05401, USA
Neurobiol Aging 34:1145-7. 2013..These findings suggest that subjective cognitive complaints in postmenopausal women might be associated with increased cortical activity during effort-demanding cognitive tasks...
Estradiol treatment altered anticholinergic-related brain activation during working memory in postmenopausal womenJulie A Dumas

The Stroop effect in kana and kanji scripts in native Japanese speakers: an fMRI studyEmily L Coderre
Department of Psychiatry, University of Vermont College of Medicine, 1 South Prospect Street, Burlington, VT 05401, USA
Brain Lang 107:124-32. 2008..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...
Nicotinic versus muscarinic blockade alters verbal working memory-related brain activity in older womenJulie A Dumas
Department of Psychiatry, Clinical Neuroscience Research Unit, University of Vermont College of Medicine, Burlington, VT 05401, USA
