Researchers at the Athinoula A Martinos Center for Biomedical Imaging have successfully developed a human brain-scale magnetic particle imaging (MPI) system, a significant breakthrough in medical imaging technology. The new system, which uses superparamagnetic iron oxide nanoparticles (SPIONs) to visualize the brain, has demonstrated a spatial resolution of about 7 mm and a temporal resolution…
An international team of researchers has made a groundbreaking discovery in brain analysis, developing new techniques that consider interactions between three or more regions of the brain. This breakthrough could lead to a deeper understanding of human brain activity and potentially aid in the diagnosis and treatment of neurological disorders. The team’s approach combines topological…
Scientists have made a groundbreaking discovery in understanding how the brain avoids ‘catastrophic forgetting’ – the distortion and overwriting of previously established memories when new ones are created. Research has shown that the brain processes new and old memories in separate phases of sleep, which might prevent mixing between the two. This finding, published in…
Scientists have developed an experimental screening method that pairs dogs with artificial intelligence to detect the odor of cancer carried on patients’ breaths. The canine-AI duo was highly accurate and sensitive, successfully spotting four types of cancer in 94% of cases. This breakthrough could lead to earlier cancer detection and increased survival rates. Forecast for…
Researchers have made a groundbreaking discovery about the structure of axons, the thin tendrils that transmit messages in the nervous system. Using a high-pressure freezing method, scientists found that axons may have a beaded or pearled shape, rather than the smooth lines previously thought. This new finding could have significant implications for our understanding of…
A team of scientists in the US has developed a non-invasive headset device that tracks changes in blood flow to assess a patient’s stroke risk. This innovative technology could make it easier to detect early signs of stroke, offering patients and physicians a direct and cost-effective approach to stroke prevention. The device uses laser-based technology…
Scientists have developed a groundbreaking new technology that uses spray-on tattoos to collect brain activity without the discomfort and limitations of traditional EEG tests. These electronic tattoos, which can be printed onto the scalp using a microjet printer, are waterproof, long-lasting, and can be easily removed with soap and water. This innovative technology has the…
Scientists have made a groundbreaking discovery in understanding the human brain’s unique genetic features, which could lead to new therapies for conditions such as Parkinson’s disease and schizophrenia. By comparing human and primate brain cells, researchers found that human dopamine neurons express more genes that boost the activity of damage-reducing antioxidants, allowing them to cope…
Scientists at MIT have made a significant breakthrough in brain stimulation by developing magnetic nanoparticles called magnetoelectric nanodiscs (MENDs) that can be used to stimulate neurons without the need for invasive surgery. These nanoparticles, which are approximately 250 nm across, can be injected into a specific location in the brain and stimulated with an electromagnet…
