As many as 7% of moms-to-be use marijuana while pregnant, and that number is rising fast as more use it to quell morning sickness. But new research suggests such use could have a lasting impact on the fetal brain, influencing children's...
Researchers followed 547 children for a week and measured their media use and sleep patterns. For children who generally struggle to self-regulate their behavior, screen time in the hour before bed was associated with less sleep. Media...
Researchers show that an online program developed specifically for AYA cancer survivors can significantly alleviate insomnia and improve overall quality of life.
Teenagers who experience very poor sleep may be more likely to experience poor mental health in later life, as depressed teens in study slept 30 minutes less per night than other groups.
Researchers looking at mouse models found impaired functional interactions between the hippocampus and the parietal cortex during the memory replay period, which may yield new insights into Alzheimer's Disease.
Older men who have a weak or irregular circadian rhythm guiding their daily cycles of rest and activity are more likely to later develop Parkinson's disease, according to a new study.
Methylation and the circadian clock are both conserved mechanisms found in all organisms. Researchers found that inhibiting methylation with a specific compound disrupts the circadian clock in most organisms except bacteria. The team...
Two new studies show that relaxed school and work schedules and more time spent at home has led people to sleep more on average with less 'social jetlag' as indicated by a reduced shift in sleep timing and duration on work days versus...
Researchers have found that activity in adult-born neurons (ABNs) in the hippocampus, which is a brain region associated with memory, are responsible for memory consolidation during REM sleep. Identifying the role of specific neurons in...
Adult neurogenesis, in which new neurons are generated within the hippocampus in the fully developed adult brain, occurs in mice -- but how new neurons are functionally integrated into existing brain circuitry has remained largely...
Sleep disruption has been shown to be associated with an increased risk of atherosclerosis, but the mechanism has been unclear. A new study reveals that fragmented sleep exacerbates atherosclerosis and may raise the risk of stroke via an...
A new study finds a causal link between sleep deprivation and death. In sleep-deprived fruit flies, death is preceded by the accumulation of molecules known as reactive oxidative species in the gut. When fruit flies were given...
A series of new studies finds, among other important discoveries, that noradrenaline, a neurotransmitter secreted in response to stress, lies at the heart of our ability to ''shut off'' our sensory responses and sleep soundly.
Do you remember the challenge of waking up on winter's cold, dark days? Neurobiologists have uncovered a clue to what's behind this behavior. In a study of the fruit fly, the researchers have identified a 'thermometer' circuit that...
New research found that substituting prolonged sedentary time with sleep was associated with lower stress, better mood and lower body mass index (BMI), and substituting light physical activity was associated with improved mood and lower...
Scientists have shown that the brain suppresses information from the outside world, such as the sound of a conversation, during the sleep phase linked to dreaming. This ability could be one of the protective mechanisms of dreams.
A research team has reported in vivo findings that a certain presynaptic cell adhesion molecule named is crucial for the development of synapses in the developing brain.
New research finds that sleep problems in a baby's first 12 months may not only precede an autism diagnosis, but also may be associated with altered growth trajectory in a key part of the brain, the hippocampus.
The reason why we sleep remains an unresolved question of the 21st century. Research now shows that the depth of non-rapid-eye-movement (nonREM) sleep in humans is associated with different genetic versions of a gene that encodes a water...
Sleep patterns around the world have been disrupted as screen time increases and sleep routines change with COVID-19 self-isolation requirements. Negative mood is not unusual in adolescence, but lack of sleep can affect mental health,...
Ketamine alleviates depressive symptoms within hours, with the most significant change typically seen a day after its administration. However, the symptoms often reappear within a week. According to researchers, neural connections...
Can staying up late make you fat? Researchers found the opposite to be true when they studied sleep in worms: It's not the sleep loss that leads to obesity, but rather that excess weight can cause poor sleep.
Going to bed early and following a consistent bedtime routine may help reduce children's risk of becoming overweight or obese, according to a new study published in Acta Paediatrica.
While sleeping the brain goes through previously experienced things, consolidates new memory contents and summarizes similar experiences into more general knowledge. This also applies to babies. However, they can more than just...
College students who listened to classical music by Beethoven and Chopin during a computer-interactive lecture on microeconomics -- and heard the music played again that night -- did better on a test the next day than did peers who heard...
Scientists have succeeded in the discovery of novel compounds to lengthen the period of the circadian clock, and has shed light on their mechanisms of action.
Researchers found that individuals going to bed even 30 minutes later than their usual bedtime presented a significantly higher resting heart rate that lasted into the following day.
Researchers identified neurons that promote non-REM sleep in the brainstem in mice. These neurons commonly expressed the gene that encodes the neuropeptide neurotensin. Activation of these neurons induced non-REM sleep. Moreover, direct...
Compared with people who slept for longer or shorter periods of time, those who reported sleeping seven or eight hours a night had significantly less evidence of stiffness in their arteries, indicating a lower chance of developing heart...
An important biological mechanism that is thought to protect brain cells from neurodegenerative diseases such as Alzheimer's and Parkinson's may also be involved in regulating sleep, according to new research.
Disrupted and poor quality sleep in the earliest months of a child's life can be an indicator of depression, anxiety and behavioral problems among toddlers, according to a new study.
Persistent sleep difficulties during the first 12 months of life are linked to a heightened risk of developing childhood anxieties and emotional disorders, indicates research.
New research shows that animals on a prebiotic diet sleep better and are buffered from the physiological impacts of stress. The undigestible dietary compounds, found in fibrous foods and some dairy products, serve as nourishment for...
People with mild traumatic brain injury who are exposed to early morning blue light therapy may experience a decrease in depression and other concussion symptoms, according to a preliminary study.
Artificial intelligence has the potential to improve efficiencies and precision in sleep medicine, resulting in more patient-centered care and better outcomes, according to a new position statement.
Study found that adequate sleep allowed students to cope with discrimination and challenges associated with ethnic or racial bias. It also helps them problem-solve more effectively and seek peer support when faced with hardships.
A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme 'morning larks' because their internal clocks operate on a 20-hour...
Depression, anxiety, impulsive behavior and poor cognitive performance in children is affected by the amount of sleep they have, researchers have found.
