Scientists have developed a novel, detailed map at the subcellular level of a brain region frequently impacted by Alzheimer’s disease. This groundbreaking achievement represents a significant advancement in understanding the mechanisms underlying the development of this neurodegenerative condition.

New research shows that AI can identify complex regional pain syndrome (CRPS) with over 90% accuracy by analyzing gut microbiome patterns.

Mindfulness exercises paired with music were found to engage both neural and cardiac systems, potentially reducing symptoms of anxiety and depression. A recent study showed that live and virtual music mindfulness sessions lowered stress and altered states of consciousness, though only live sessions fostered social connection.

A long-term study shows that teenagers who maintain or increase physical activity levels are less likely to develop symptoms of depression.

Researchers have developed a brain-computer interface (BCI) that enables computer cursor control and clicking, using neural signals from the speech motor cortex. One participant with amyotrophic lateral sclerosis (ALS) used the interface for daily life activities, including independent control of a personal desktop computer and text entry.

New research shows that targeting emotional processing is key to treating and managing chronic pain.

In a first-of-its-kind clinical study, researchers have shown that patients with treatment-resistant PTSD were symptom-free up to six months after completing traditional therapy paired with vagus nerve stimulation (VNS).

Scientists using living human brain tissue have shown for the first time how a toxic form of a protein linked to Alzheimer’s can stick to and damage the connections between brain cells.

People whose biological age is higher than their chronological age may be more likely to develop dementia than people whose biological age matches or is lower than their chronological age, according to a study published online in Neurology. Biological age is based on biomarkers of aging such as lung function, blood pressure and cholesterol.

A recent study reveals that oxygen tension elevation during weeks four to six promotes neurogenesis in brain organoids, regulated by neuroglobin. The research is published in Science Advances.

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain’s small blood vessels, according to a study published in Neurology.

A new theory suggests that psychedelics promote empathy, insight, and psychological flexibility by making the brain’s right hemisphere temporarily dominant over the left.

A revolutionary microscopy method called LICONN enables scientists to reconstruct brain tissue and map synaptic connections using standard light microscopes. By embedding brain tissue in hydrogel, expanding it, and imaging at nanoscale resolution, researchers achieve a detailed view of neuronal architecture previously only possible with electron microscopy.

A new music therapy-based tool called MuSICCA may transform how healthcare teams assess consciousness in children with severe brain injuries.

Research from Emory University has identified a biological connection between inflammation and deficits in motivation in individuals with schizophrenia, offering new hope for treating symptoms that have long been resistant to existing therapies.

A Yale-led study shows that the senses stimulate a region of the brain that controls consciousness—a finding that might inform treatment for disorders related to attention, arousal, and more.

Finally this week, a new study has debunked the common myth that autistic people are less effective communicators than non-autistic individuals. Researchers found no difference in how well information was shared between autistic-only, non-autistic-only, or mixed groups.

A new study suggests that different brain regions activated by creative tasks are part of one common brain circuit. By evaluating data from 857 participants across 36 fMRI studies, researchers identified a brain circuit for creativity and found people with brain injuries or neurodegenerative diseases that affect this circuit may have increased creativity.

New research has uncovered why males and females may experience stress differently, providing insights into how the brain’s molecular mechanisms adapt to acute challenges.

How can nerve pathways in the brain be visualized to improve the planning of complex surgeries? A research team has investigated an AI-powered method that makes these reconstructions more precise. The study, recently published in NeuroImage: Clinical, could ultimately help make neurosurgical procedures safer.

Three studies at the University of Zurich demonstrate that hypnosis alters activity in the large-scale functional networks of the brain. It also affects the neurochemical milieu of specific brain areas.

New research reveals that brain cells use a muscle-like signaling mechanism to relay information over long distances. Scientists discovered that dendrites, the branch-like extensions of neurons, contain a structured network of contact sites that amplify calcium signals—similar to how muscles contract. These contact sites regulate calcium release, activating key proteins involved in learning and memory.

Researchers have made a major breakthrough in understanding the link between genetics and cognition.

A recent large-scale study published in Science Advances has revealed a connection between genetic variations associated with dyslexia and structural differences in the brain. These differences were found in areas involved in motor coordination, vision, and language. This provides new insights into the neurological underpinnings of this common learning difficulty.

According to a recent study, a diet low in vegetables and fruits and high in red meat, fast food, and sugar-sweetened soft drinks was associated with accelerated biological aging.

A new mathematical model sheds light on how the brain processes different cues, such as sights and sounds, during decision making. The findings may one day improve how brain circuits go awry in neurological disorders, such as Alzheimer’s, and could help artificial brains, like Alexa or self-driving car technology, more helpful.

New research has shown just one 20-minute session of moderate intensity aerobic exercise can improve an athlete’s executive function and concussion symptoms in the early stages of recovery.

A recent study using brain imaging technology discovered that experiencing beauty in music involves increased communication between brain areas associated with reward and visual processing, while listening to music considered less beautiful is linked to more activity in brain regions responsible for basic sensory processing.

Finally this week, women with epilepsy may have offspring with decreased bone metabolism and lower birth weight, according to a study published in the Annals of Clinical and Translational Neurology.
