EEG connectivity across sleep cycles and age
(American academy of sleep medicine, 2019-11-06)
Study Objectives
In young adults, sleep is associated with important changes in cerebral connectivity during the first cycle of non-rapid eye movement (NREM) sleep. Our study aimed to evaluate how electroencephalography ...
Gray matter hypertrophy and thickening with obstructive sleep apnea in middle-aged and older adults
Gray matter increases with obstructive sleep apnea
(American Thoracic Society, 2017-06-01)
Rationale: Obstructive sleep apnea causes intermittent hypoxemia, hemodynamic fluctuations,
and sleep fragmentation, all of which could damage cerebral gray matter that can be indirectly
assessed with neuroimaging.
Objectives: ...
Aging and language : maintenance of morphological representations in older adults
(Frontiers media, 2019-05-15)
Studies employing primed lexical decision tasks have revealed morphological facilitation
effects in children and young adults. It is unknown if this effect is preserved or diminished
in older adults. In fact, only few ...
Relationships between years of education, regional grey matter volumes, and working memoryrelated brain activity in healthy older adults
(Springer, 2017-04)
The aim of this study was to examine the relationships between educational attainment, regional
grey matter volume, and functional working memory-related brain activation in older adults. The
final sample included 32 ...
Aging reduces the stimulating effect of blue light on cognitive brain functions
(Oxford University Press, 2014-01-01)
Study Objectives:
Light exposure, particularly blue light, is being recognized as a potent mean to stimulate alertness and cognition in young individuals. Aging is associated with changes in alertness regulation and ...
Regional cerebral blood flow during wakeful rest in older subjects with mild to severe obstructive sleep apnea
Cerebral perfusion in OSA
(Oxford University Press, 2015)
Objectives: To evaluate changes in regional cerebral blood flow (rCBF) during wakeful rest in older
subjects with mild to severe obstructive sleep apnea (OSA) and healthy controls, and to identify
markers of OSA severity ...
