A secondary analysis of the ANGEL-ASPECT trial found EVT to be beneficial for patients with anterior-circulation LVO and a large ischemic core and absent-to-moderate white matter lesions. In contrast, those with severe WMLs showed less pronounced benefits, suggesting uncertainty about EVT's efficacy in this subgroup.
A systematic review and meta-analysis of 33 studies found that nature exposure is associated with reductions in negative emotions and increases in positive emotions. Experts recommend integrating nature into urban design to promote brain health and treat mental illnesses.
Researchers discovered that oscillatory activity in two brain regions plays a crucial role in integrating auditory and visual information during memory recall. The study used movie clips with synchronized or asynchronous speech sounds and lip movements to explore this phenomenon.
Researchers found that perceiving prices significantly different from expectations triggers a strong N400 signal in the brain, engaging regions involved in evaluating rewards and learning. This suggests that consumers' perceptions of value are part of automatic cognitive mechanisms activated long before conscious decision-making.
Researchers have identified changes in brain rhythms that indicate seizure activity in Alzheimer's patients. High-frequency oscillations (HFOs) occur at rates two to three times higher in Alzheimer's patients than in cognitively normal individuals.
Researchers have developed a highly sensitive diamond quantum magnetometer that can achieve practical ambient condition magnetoencephalography. The novel magnetometer uses a single crystalline diamond to detect magnetic fields, achieving record sensitivities of up to 9.4 pT Hz-1/2 in the frequency range of 5 to 100 Hz.
A study published in PLOS Biology found that negating adjectives affects brain processing, with slower reaction times and varied interpretations. The researchers used magnetoencephalography to capture brain activity while participants rated affirmative or negated phrases.
A team of researchers from New York University recruited 30 stutterers and monitored their brain activity using magnetoencephalography (MEG) while they spoke. The study found increased beta waves associated with cues that preceded stuttered words, suggesting a predictive link between brain activity and stuttering.
Researchers investigated the neural mechanisms of verbal working memory processing in healthy aging adults using magnetoencephalography. Age-related increases in theta activity were detected during encoding, and alpha and beta oscillations were stronger in older participants during maintenance and retrieval phases.
A new study finds epigenetic aging is associated with aberrant neural oscillatory dynamics serving visuospatial processing in people with HIV. Participants showed accelerated biological age and different brain activity patterns compared to controls, suggesting a link between biological aging and neural function in PWH.
Researchers have identified a new marker for predicting the clinical outcome of patients with Amyotrophic Lateral Sclerosis (ALS) by analyzing brain flexibility during rest. The study found that brains with more flexible functional repertoires tend to have better clinical outcomes.
Researchers used magnetoencephalography to study age-related changes in gamma-band oscillations in the auditory cortex of typically developing children. The results showed that power increased with age and cortical localization changed, indicating an age-related shift in the balance between excitation and inhibition.
Researchers have developed ultra-thin, defect-free superconducting flakes for use in quantum computing. The twist angle of the flakes is used to modulate the maximum supercurrent, creating an extremely sensitive magnetic field sensor. This breakthrough has potential applications in healthcare and mineral exploration.
Researchers at the University of Birmingham discovered that humans process written words rapidly, using pre-processing judgments within 100ms, and that this activity is linked to the complexity of the word. This study has significant implications for diagnosing and training individuals with dyslexia where pre-processing is impaired.
Researchers used MEG to measure brain activity while participants listened to simultaneous math equations and sentences, finding separate networks for each. The parietal lobe processed math and the temporal lobe processed language, with activity tracking every word and symbol.
A team from the Russian Quantum Center developed a novel solid-state supersensitive room-temperature magnetometer capable of registering weak electrical sources in the brain. The device successfully detected alpha rhythm, a sinusoidal electric current in the back of the brain, and showed higher sensitivity than existing systems.
Researchers from HSE University developed a new method to process MEG data, enabling cortical activation areas with higher precision. This improvement allows for better diagnosis of neurological disorders and preparation for brain surgery.
Wolfgang Baumeister and Riitta Hari develop cryoelectron tomography to visualize molecular complexes in cells, while Nikos Logothetis studies the basis of visual awareness in trained monkeys. These advances may provide insight into changes during synaptic activation and social cognition.
