A new study unveiled a crucial role of sleep: brainwaves facilitating the cleansing of the brain by flushing out waste. This discovery not only underscores the brain's non-dormant state during sleep but also highlights a sophisticated system where neurons' synchronized activity powers the flow of cerebrospinal fluid, effectively removing metabolic waste and potentially neurodegenerative disease-causing toxins.
New research challenges Pythagoras's ancient theory on musical consonance, revealing our preference for slight imperfections in chords rather than the perfect integer ratios traditionally associated with beautiful music. The study highlights how the mathematical relationships deemed crucial for a chord's beauty disappear with instruments unfamiliar to Western traditions, such as the Javanese gamelan's bonang.
A new study reveals the oxygenation levels in the placenta during the last trimester of pregnancy are a key predictor of the development of the cerebral cortex and likely childhood cognition and behavior. Utilizing magnetic resonance imaging (MRI) for a more accurate assessment of placental health, the study offers new insights into how the placenta mediates the impact of maternal health on fetal brain development.

Neurology news articles cover neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.

A new study found that the speed of speech, rather than the difficulty in finding words, is a more accurate indicator of brain health in older adults. The research, involving 125 healthy volunteers aged 18 to 90, utilized AI software to analyze language performance, focusing on speech rate and word-finding pauses.
Researchers introduced a groundbreaking non-invasive brain stimulation technique called Patterned Low-Intensity Low-Frequency Ultrasound (LILFUS). This innovative method can precisely target and modulate specific brain regions, offering a promising alternative to traditional magnetic, electrical, and surgical brain stimulation methods with fewer risks.
Researchers achieved a breakthrough in mapping the brain's 'dysfunctome'—key dysfunctional circuits linked to disorders like Parkinson’s, dystonia, OCD, and Tourette’s syndrome. Utilizing deep brain stimulation (DBS) data from 261 patients worldwide, they pinpointed specific frontal cortex circuits crucial for symptom improvement.

AI news articles cover science articles about artificial intelligence including ChatGPT, Bard, Dalle, neural networks, machine learning, LLMs, AGI and other AI related topics.

Affective computing is transforming how machines understand human emotions, enabling them to respond to our feelings in real-time. This interdisciplinary field merges computer science, psychology, and neuroscience, aiming to enhance human-machine interactions.
A new study combines deep learning with neural activity data from mice to unlock the mystery of how they navigate their environment. By analyzing the firing patterns of "head direction" neurons and "grid cells," researchers can now accurately predict a mouse's location and orientation, shedding light on the complex brain functions involved in navigation.
Researchers have developed an AI method that can predict Alzheimer's Disease up to seven years before the onset of symptoms, utilizing machine learning to analyze patient records. Their study highlights high cholesterol and osteoporosis—particularly in women—as key predictors, showcasing AI's potential to unveil complex disease patterns and biological drivers.

Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.

Researchers provide novel insights into female psychopathy, challenging the conventional 6:1 male-to-female psychopath ratio with new evidence suggesting a closer 1.2:1 ratio. The research indicates that societal gender biases have obscured the true nature and prevalence of female psychopaths, who often employ manipulation and seduction rather than violence to achieve their goals.
Live music significantly amplifies emotional responses in the brain compared to recorded tunes. By measuring amygdala activity, researchers found that live performances evoke stronger emotional reactions, fostering a deeper cognitive and affective processing throughout the brain.
A groundbreaking cross-cultural study has revealed that music universally influences bodily sensations and emotions, transcending cultural boundaries. Researchers from Western and East Asian backgrounds discovered that emotional and structural characteristics of music consistently evoke similar bodily sensations—such as changes in the chest, limbs, and head regions—regardless of cultural background.

Researchers developed the world's first 3D-printed brain tissue that grows and behaves similarly to natural brain tissue, marking a significant leap forward for neurological and neurodevelopmental disorder research. This novel 3D-printing technique uses a horizontal layering approach and a softer bio-ink, allowing neurons to interconnect and form networks akin to human brain structures.
Researchers have discovered a molecular complex crucial for the transport of mitochondria within neurons, offering new insights into preventing neurodegenerative diseases. The complex, identified as Alex3/Gαq, is pivotal for distributing energy-producing mitochondria throughout neurons, essential for neurotransmission and neuronal functions.
Researchers unlocked how the brain processes melodies, creating a detailed map of auditory cortex activity. Their study reveals that the brain engages in dual tasks when hearing music: tracking pitch with neurons used for speech and predicting future notes with music-specific neurons.
Researchers developed an innovated a technique to convert complex neuroimaging data into audiovisual formats. By transforming brain activity and blood flow data from behaviors like running or grooming in mice into synchronized piano and violin sounds, accompanied by video, they offer an intuitive approach to explore the brain's intricate workings.
