The rich have one more thing you don’t: Better #sleep

..Of the adults surveyed, only 55% of people living below the poverty threshold received seven to eight hours of sleep per night. For adults making 400% above the poverty threshold, that number rose to 66.6%. In 2014, the poverty threshold was $11,670 for a single-person household and $23,850 for a four-person household. ..Sleep affects many… Continue reading The rich have one more thing you don’t: Better #sleep

Mild to moderate partial #sleep deprivation is associated with increased #impulsivity and decreased positive affect in young adults

The effects of mild–moderate partial sleep deprivation on affective and cognitive functioning were evaluated in a naturalistic home environment, mimicking short sleep typically caused by demands from work or society. A total of 52 healthy individuals aged 18–35 was included in an 11-day study protocol. Participants slept at home, and sleep patterns were observed using… Continue reading Mild to moderate partial #sleep deprivation is associated with increased #impulsivity and decreased positive affect in young adults

The human #cerebellum has almost 80% of the surface area of the #neocortex

The surface of the human cerebellar cortex is much more tightly folded than the cerebral cortex. It was computationally reconstructed for the first time to the level of all individual folia from multicontrast high-resolution postmortem MRI scans. Its total shrinkage-corrected surface area (1,590 cm2) was larger than expected or previously reported, equal to 78% of… Continue reading The human #cerebellum has almost 80% of the surface area of the #neocortex

Conservation of #brain connectivity and wiring across the mammalian class

Over 100 years ago, Ramon y Cajal hypothesized that two forces played a role in the evolution of mammalian brain connectivity: minimizing wiring costs and maximizing conductivity speed. Using diffusion MRI, we reconstructed the brain connectomes of 123 mammalian species. Network analysis revealed that both connectivity and the wiring cost are conserved across mammals. We… Continue reading Conservation of #brain connectivity and wiring across the mammalian class

Complementary contributions of non-REM and #REM sleep to visual #learning

Sleep is beneficial for learning. However, it remains unclear whether learning is facilitated by non-rapid eye movement (NREM) sleep or by REM sleep, whether it results from plasticity increases or stabilization, and whether facilitation results from learning-specific processing. Here, we trained volunteers on a visual task and measured the excitatory and inhibitory (E/I) balance in… Continue reading Complementary contributions of non-REM and #REM sleep to visual #learning

Nine-year prospective efficacy and safety of brain-responsive #neurostimulation for focal #epilepsy

Prospectively evaluate safety and efficacy of brain-responsive neurostimulation in adults with medically intractable focal onset seizures (FOS) over 9 years.. Adults treated with brain-responsive neurostimulation within 2 year feasibility or randomized controlled trials enrolled into a long-term prospective open label trial (LTT) to assess safety, efficacy, and quality of life (QOL) over an additional 7… Continue reading Nine-year prospective efficacy and safety of brain-responsive #neurostimulation for focal #epilepsy

The temporal association between incident late‐life #depression and incident #dementia

There is an established association between depression and subsequent dementia. The present study examined temporal associations between incident late‐life depression and subsequent dementia, also considering age and sex.. ..Incident depression was associated with a higher risk of subsequent dementia (incidence rate ratios (IRR) adjusted for age and sex: IRR = 1.58, 95% CI = 1.51‐1.64).… Continue reading The temporal association between incident late‐life #depression and incident #dementia

Risk factors of excessive daytime #sleepiness in a prospective population‐based cohort

Although excessive daytime sleepiness is commonly evaluated in clinical and research settings using the Epworth Sleepiness Scale, few studies have assessed the factors associated with its incidence in the general population. We prospectively investigated the predictors of incident and persistent excessive daytime sleepiness in 2,751 subjects (46.1% men, mean age 56.0 ± 9.8 years) from… Continue reading Risk factors of excessive daytime #sleepiness in a prospective population‐based cohort

#Cerebrovascular and Neurological Dysfunction under the Threat of #COVID-19: Is There a Comorbid Role for #Smoking and Vaping?

The recently discovered novel coronavirus, SARS-CoV-2 (COVID-19 virus), has brought the whole world to standstill with critical challenges, affecting both health and economic sectors worldwide. Although initially, this pandemic was associated with causing severe pulmonary and respiratory disorders, recent case studies reported the association of cerebrovascular-neurological dysfunction in COVID-19 patients, which is also life-threatening. Several… Continue reading #Cerebrovascular and Neurological Dysfunction under the Threat of #COVID-19: Is There a Comorbid Role for #Smoking and Vaping?
