Article Synopsis
- - The study investigates how testosterone affects song production in adult female canaries, which typically do not sing, by analyzing gene regulatory networks in a brain area responsible for song control (HVC) over a period of time after hormone treatment.
- - Female canaries started to vocalize within four days of receiving testosterone, with both song complexity and the brain region's volume increasing over a two-week period.
- - The researchers found that a significant number of genes (over 9,900) were differentially expressed during this time, indicating a complex and dynamic relationship between testosterone and the neural mechanisms involved in song development.
Sleep and physical activity levels are both associated with cognitive performance among older adults; however, the brain mechanisms underlying these beneficial relationships remain poorly understood. This study investigated cross-sectional associations of actigraphic estimates of physical activity and sleep with cognition and diffusion imaging-based measures of medial temporal lobe (MTL) gray matter microstructural integrity in adults free of dementia. Participants were 132 older adults from the Biomarkers of Cognitive Decline Among Normal Individuals (BIOCARD) cohort study (119 cognitively unimpaired and 13 with mild cognitive impairment; mean age=70.

Advanced imaging techniques like cardiac magnetic resonance imaging (CMR) and 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (FDG-PET/CT) are effective in detecting CS but not easily accessible. The optimal method for selecting patients for advanced screening remains uncertain.

However, the current state of the knowledge is limited regarding the association with objective sleep. The present study investigated the short-term effects of workplace bullying on objective sleep patterns using an actigraphy diary approach.
