Breathing rhythms may choreograph memory retrieval

New findings in The Journal of Neuroscience report that breathing timing can influence memory retrieval. In 18 young adults, EEG and a breath sensor linked brain alpha/beta oscillations and memory reactivation to the respiratory cycle: recalling an image cue was more accurate when the cue appeared during inhalation, with memory processing aligning to exhalation. Stronger breath-brain coupling predicted better memory scores, suggesting respiration acts as a scaffold for episodic retrieval. Authors caution that effects are modest and causality isn’t proven, and results reflect spontaneous breathing rather than deliberate breathing exercises.

Brain's self-voice misfire explains hearing voices in schizophrenia

New UNSW research provides the strongest evidence to date that auditory hallucinations in schizophrenia arise when the brain mispredicts its own inner speech, treating thoughts as external voices. EEG tests across three groups (recent AVH, other schizophrenia patients, and healthy controls) showed healthy individuals reduce brain activity for matched imagined/actual sounds, while those currently hearing voices show the opposite pattern, suggesting a disruption in the brain's prediction mechanism and offering a potential biomarker for psychosis and earlier detection.

Potential Link Between Brain Receptor and Autism Uncovered

Yale researchers found that autistic adults have reduced availability of the mGlu5 glutamate receptor across the brain, supporting the theory that an imbalance in excitatory and inhibitory signaling contributes to autism traits. EEG data correlated with receptor levels suggest a potential accessible diagnostic tool, and targeting mGlu5 could lead to new treatments. The study offers rare molecular insight into autism, with future research planned in children and individuals with intellectual disabilities.

Decoding the Brain's Activity During Sleep and Dreaming

A large-scale international study challenges the idea that dreaming only occurs during REM sleep, showing that parts of the brain remain alert and can generate dreams during deep NREM sleep, with AI models being developed to detect dreams based on brain activity. This research broadens understanding of consciousness during sleep and has potential medical applications, including early detection of cognitive disorders like Alzheimer's.

Disconnected Brain Regions Enter Sleep-Like States During Wakefulness

Surgically disconnecting part of the brain in children with epilepsy causes that region to exhibit sleep-like slow brain waves, even while the person remains awake, raising questions about the nature of consciousness and brain activity after disconnection.

Brain's Attention Functions Like a Zoom Lens

A study reveals that the brain's attention system first broadly prepares to focus on general features like color or movement within 240 milliseconds, then quickly narrows down to specific details such as the exact color or direction in about 400 milliseconds, highlighting a hierarchical process that could inform understanding of attention disorders.

Breath Meditation Induces Deep Relaxation in the Brain

A study shows that breath-based meditation, specifically Sudarshan Kriya Yoga, shifts brain activity into a deeply relaxed state characterized by increased theta and delta waves and decreased alpha activity, supporting its potential for promoting mental well-being. The research used EEG to analyze brain changes during different stages of the practice, revealing consistent patterns across experienced practitioners and highlighting the technique's ability to facilitate access to meditative states.
