MRI scans from more than 800 incarcerated men pinpoint distinct structural features of people who have committed homicide, compared with those who carried out other crimes.

by NICOLETTA LANESE Kent Kiehl and his research team regularly park their long, white trailer just outside the doors of maximum-security prisons across the US. Inside the vehicle sits the bulky body of a mobile MRI machine. During each visit, people from the prison make their way to and from the vehicle in hourly shiftsContinue reading “MRI scans from more than 800 incarcerated men pinpoint distinct structural features of people who have committed homicide, compared with those who carried out other crimes.”

Scientists are now able to take an MRI Scan of an atom

By Knvul Sheikh As our devices get smaller and more sophisticated, so do the materials we use to make them. That means we have to get up close to engineer new materials. Really close. Different microscopy techniques allow scientists to see the nucleotide-by-nucleotide genetic sequences in cells down to the resolution of a couple atomsContinue reading “Scientists are now able to take an MRI Scan of an atom”

AI and MRIs at birth can predict cognitive development at age 2

Researchers at the University of North Carolina School of Medicine used MRI brain scans and machine learning techniques at birth to predict cognitive development at age 2 years with 95 percent accuracy. “This prediction could help identify children at risk for poor cognitive development shortly after birth with high accuracy,” said senior author John H.Continue reading “AI and MRIs at birth can predict cognitive development at age 2”

Playing video games may increase your brain’s gray matter and improve how it communicates

According to the results of a study published in Nature, gaming could possibly increase the volume of gray matter in the brain. Researchers recently studied the insular cortex regions of frequent gamers and those who didn’t play video games as regularly. The study found a correlation between playing action video games and increased gray matterContinue reading “Playing video games may increase your brain’s gray matter and improve how it communicates”

‘Mindful people’ feel less pain; MRI imaging pinpoints supporting brain activity

Greater deactivation of the posterior cingulate cortex, a brain region associated with processing self-related thoughts, was associated with lower pain and higher trait mindfulness. Credit: Wake Forest Baptist Medical Center Ever wonder why some people seem to feel less pain than others? A study conducted at Wake Forest School of Medicine may have found oneContinue reading “‘Mindful people’ feel less pain; MRI imaging pinpoints supporting brain activity”

Superslow Brain Waves May Play a Critical Role in Consciousness

Signals long thought to be “noise” appear to represent a distinct form of brain activity. By Tanya Lewis Every few seconds a wave of electrical activity travels through the brain, like a large swell moving through the ocean. Scientists first detected these ultraslow undulations decades ago in functional magnetic resonance imaging (fMRI) scans of peopleContinue reading “Superslow Brain Waves May Play a Critical Role in Consciousness”

New research links subgroups of schizophrenia to specific visualized brain anomalies

An international team of researchers has linked specific symptoms of schizophrenia with various anatomical characteristics in the brain, according to research published in NeuroImage. By analyzing the brain’s anatomy with magnetic resonance imaging (MRI), researchers from the University of Granada, Washington University in St. Louis, and the University of South Florida have demonstrated the existenceContinue reading “New research links subgroups of schizophrenia to specific visualized brain anomalies”

Mother-child MRI

While most new moms get their children’s first portrait done at, say, the local mall’s JC Penney Portrait Studio, neuroscientist Rebecca Saxe opted for a slightly different location: the tube of an MRI scanner. “No one, to my knowledge, had ever made an MR image of a mother and child,” she wrote in a articleContinue reading “Mother-child MRI”

Mummified monk revealed inside 1,000-year-old Buddha statue

Scientific tests have revealed that an ancient Buddhist statue contains the perfectly preserved remains of a 1,000-year-old mummified monk, in what is believed to be the only such example in the world. The monk, who is sitting in the lotus position, is thought to have starved himself to death in an act of extreme spiritualContinue reading “Mummified monk revealed inside 1,000-year-old Buddha statue”

New research may help explain why curiosity promotes better memory

Everyone knows it’s easier to learn about a topic you’re curious about. Now, a new study reveals what’s going on in the brain during that process, revealing that such curiosity may give a person a memory boost. When participants in the study were feeling curious, they were better at remembering information even about unrelated topics,Continue reading “New research may help explain why curiosity promotes better memory”
