Some parts of the brain tend to atrophy and deform in concert with other regions. Credit: Zephyr/SPLA comprehensive analysis of nearly 50,000 brain scans has identified five unique patterns of brain atrophy linked to aging and neurodegenerative diseases. The study also connected these patterns to lifestyle factors such as smoking and alcohol consumption, as...
Credit: PixabayNeuroscientists believe they have pinpointed the extensive neural network that fuels the brain's creativity. Unlike specific movements or sensory responses, creative thinking is not limited to a single area of the brain's outer cortex. However, researchers from Baylor College of Medicine have identified the brain circuits crucial to certain types of creative thought.When...
Selective serotonin releasing agent is not negated by 5-HT1A supersensitivity, resulting in a rapid onset of pro-serotonergic activity. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-50394-xAccording to a new study in Nature Communications, increasing serotonin can alter how people learn from negative information and enhance their response to it.Researchers from the University of Oxford's Department of Psychiatry and...
A new molecule that switched memory and cognition back on in mice with Alzheimer's could one day do the same for humans, as illustrated in this generative imageInstead of focusing on fighting the plaques associated with Alzheimer's, researchers decided to explore the possibility of increasing electrical oscillations in the brain. They created a molecule...
Electrodes in multiple brain regions monitor real-time brain activity. Colored dots on the images indicate electrode locations across all patients, color-coded by brain region, with red dots highlighting electrodes in the DMN. Credit: Brain (2024). DOI: 10.1093/brain/awae199Have you ever experienced a sudden breakthrough on a tough problem while thinking about something entirely different? This kind of...

While handedness is well-known as a defining characteristic, the study reveals lesser-known biases that impact social dynamics and cognitive functions.Human Biases and Brain LateralizationHumans exhibit a strong tendency towards right-handedness,...

Researchers at the Mayo Clinic and collaborators have now identified unique molecular signatures of BBB dysfunction, potentially leading to new diagnostic and treatment methods.Discovery and Analysis of Molecular Signatures"These...
Credit: CanvasSeeing and understanding objects in our surroundings is an important job for our eyes. One way our brain does this is by separating objects from their backgrounds. We call this process "figure-ground organization." An interesting example is the Edgar Rubin vase illusion, where we see either a vase or two faces, but...
Neuralink's first human patient, Noland Arbaugh, has has some issues with the device, but still loves itNeuralinkNoland Arbaugh became a quadriplegic after a swimming accident in 2016. In January of this year, he became the first person to receive Elon Musk's Neuralink brain implant, known as the Link, which aims to grant him telekinetic...
