Can a Disconnected Brain Be Conscious?

A new study reveals that sleep-like slow-wave brain activity can persist for years in surgically disconnected brain hemispheres of awake epilepsy patients. Using EEG recordings, researchers found that the isolated cortex exhibits patterns similar to deep sleep, anesthesia, or vegetative states—suggesting absent or reduced awareness.

Five Sleep Types Revealed: How Your Brain Wiring Reflects Rest

A new study has identified five distinct “sleep-biopsychosocial” profiles that connect how we sleep with our brain networks, mental health, cognition, and lifestyle. Using data from over 700 participants, researchers found that different sleep patterns—ranging from poor quality to resilience and short duration—each showed unique neural connectivity patterns.

What You Choose to Remember Shapes Memory More Than Emotion

A new study reveals that intentional memory control—deciding what to remember or forget—is more powerful than emotional influence when forming long-term memories. Participants were more likely to recall words they were told to remember than those carrying emotional weight, even though emotion sometimes strengthened recall or caused false memories.

When Mom Struggles to Bond, Babies Sleep Worse

A large Finnish study has found that mothers who struggle to bond with their infants are more likely to have children with sleep problems that persist into toddlerhood. Difficulties in bonding at eight months were linked to sleep disruptions, including frequent awakenings and trouble falling asleep, even at age two.

Sleep Disorders Predict Parkinson’s or Dementia Years Ahead

Two landmark international studies show that brain biomarkers can predict whether people with REM sleep behaviour disorder (iRBD) will develop Parkinson’s disease or dementia with Lewy bodies (DLB). MRI scans revealed that reduced glymphatic system function signals higher risk for Parkinson’s, while increased free water in the basal nucleus of Meynert predicts progression to DLB.

Gut Microbes May Hold the Hidden Key to Why We Sleep

A new study shows that bacterial cell wall molecules, specifically peptidoglycan, are present in the brain and fluctuate with sleep cycles. This finding supports a hypothesis that sleep is not solely brain-regulated but arises from the interplay between the body and its microbiome.

Brain Waves During Sleep Are Driven by Neural Excitability

New research shows that slow oscillations in the brain, which occur during deep sleep and anesthesia, are guided by neuronal excitability rather than structural anatomy. Using computational models and experiments in mice, scientists demonstrated that the most excitable brain region directs the flow of these waves, like a leader setting a trend.

Cooler Nights and Brighter Days Boost Sleep in Dementia Patients

A large-scale study shows that indoor environmental changes—such as cooler bedroom temperatures at night and brighter indoor light during the day—can significantly improve sleep in people living with dementia. Researchers analyzed over 26,000 days of data using contactless sensors placed in participants’ homes.

REM Sleep Reactivation Locks Memories in Place

Rare adult-born neurons in the hippocampus are reactivated during REM sleep, locking waking experiences into long-term memory. Using genetically modified mice, they found that these neurons fire in the same patterns during sleep as they did during learning.

Cannabis Linked to Reduced Insomnia and Anxiety

A new study suggests cannabis-based medical products may help people with insomnia sleep better over the long term. Across 124 patients followed for up to 18 months, participants consistently reported improved sleep quality, less anxiety and depression, and a better overall quality of life.

Omega-3s May Protect Against Daytime Sleepiness

A new study has identified seven blood metabolites linked to excessive daytime sleepiness (EDS), a condition affecting one in three Americans. The findings show that both diet and hormones play a role, with omega-3 and omega-6 fatty acids associated with lower risk, and compounds like tyramine linked to higher risk.

This shows a brain and a night time backdrop.

Nighttime Brain Activity Keeps Glucose Levels in Check

A new study reveals that the brain actively maintains blood sugar stability during everyday life, not just during crises. Researchers identified VMHCckbr neurons in the hypothalamus that regulate glucose by promoting fat breakdown, especially during the early hours of sleep.
