Shared Brain Circuit Links Insomnia, Anxiety, and Depression

A large brain imaging study suggests that insomnia, depression, and anxiety—often co-occurring—share overlapping brain abnormalities. Researchers found reduced cortical surface area, smaller thalamic volume, and weaker brain connectivity across all three disorders, while each also displayed unique neural patterns.

What Poor Sleep Really Does to Your Brain

Chronic sleep disorders and short-term sleep deprivation affect different regions of the brain, highlighting distinct neural impacts. A meta-analysis of 231 brain studies showed that chronic sleep disorders alter regions involved in emotions and memory, while short-term deprivation primarily affects attention and movement regulation.

Sleep Prepares the Brain for Both Past Memories and Future Learning

A new study reveals that sleep not only consolidates existing memories but also primes the brain for future learning. Researchers tracked neuronal activity in mice and discovered 'engram-to-be cells' that synchronize during sleep, preparing to encode new experiences.

What Makes Dreams Memorable? Study Reveals Three Key Predictors

Not everyone remembers their dreams, and a new study reveals why. Researchers found that dream recall is most strongly influenced by a person’s attitude toward dreams, their tendency to mind-wander, and specific sleep characteristics.

Earlier Bedtimes Linked to Better Brain Function in Adolescents

A large-scale study has found that adolescents who go to bed earlier and get slightly more sleep show better brain function and higher cognitive test performance than their peers. Using wearable devices and brain imaging from over 4,000 participants, researchers discovered that even small differences in sleep duration and timing impacted brain volume and task performance.

Lucid Dreaming Reveals a New Layer of Conscious Brain Activity

Lucid dreaming, where people become aware they are dreaming, has long fascinated both scientists and dreamers. A new study with the largest dataset of its kind has identified distinct brain activity patterns that separate lucid dreaming from both REM sleep and wakefulness.

Gut Microbiome May Hold Key to Treating Sleep Apnea

A new review highlights growing evidence linking gut health to sleep apnea, suggesting that changes in gut microbiota may influence the severity of sleep-disordered breathing. These microbial imbalances are associated with increased inflammation, leaky gut, and impaired gut-brain communication—all of which may exacerbate obstructive sleep apnea.

Natural Light Before Waking Boosts Morning Alertness

A new study highlights how controlled exposure to natural light before waking can improve morning alertness and reduce sleepiness. Researchers tested three lighting conditions using light-shielding curtains and sensors to determine the effects of early morning light on 19 participants.

Sleep Strengthens Memory for Life Events Over a Year Later

New research reveals that a single night of sleep can enhance memory for the order of real-world experiences—lasting for over a year. In a unique study, participants took an immersive art tour and were later tested on their memory of both object features and event sequences.

Screen Time in Bed Linked to Less Sleep, Higher Insomnia Risk

A new study of over 45,000 young adults found that using screens in bed increases the risk of insomnia by 59% and cuts sleep by 24 minutes. Surprisingly, the type of activity—whether social media, movies, or studying—didn’t make a difference; it was the screen time itself that mattered most.

How Sleep, Emotion, and Novelty Shape Memory

New research highlights how smartphones are transforming memory science by capturing real-world data on sleep, emotion, and daily experiences. Studies show that replaying memories before sleep, experiencing novel events, and feeling positive emotions can all strengthen autobiographical memory.
