Researchers used brain scans to reveal the biases people feel towards people who are like them, even if they can't see that they are like them.
Sea Hero Quest is a spatial navigation video game that can be played on cell phones, tablets and virtual reality applications, developed by scientists at the CNRS, at University College London, and the University of East Anglia. A new study based on the data collected from the game has shown that poor spatial orientation as an indicator can help in early diagnosis of Alzheimer's disease, even prior to the appearance of any clinical signs.
Fruit fly studies reveal proteins that promote healthy nervous system development by preventing the reversal of nerve cell differentiation.
Having a map of the two cell receptors for melatonin could lead to better drugs to address insomnia or other conditions affected by those receptors.
Scientists used a compound found in a shrub native to Africa to reveal the three major shapes of the serotonin transporter, a protein in the brain linked to anxiety and depression. The discovery opens new avenues for developing medications to treat addiction.
An international team of researchers used an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to create the first detailed maps of two melatonin receptors that tell our bodies when to go to sleep or wake up and guide other biological processes. A better understanding of how they work could enable researchers to design better drugs to combat sleep disorders, cancer and type 2 diabetes. Their findings were published in two papers today in Nature.
A state-of-the-art brain-machine interface created by UC San Francisco neuroscientists can generate natural-sounding synthetic speech by using brain activity to control a virtual vocal tract -- an anatomically detailed computer simulation including the lips, jaw, tongue, and larynx. The study was conducted in research participants with intact speech, but the technology could one day restore the voices of people who have lost the ability to speak due to paralysis or neurological damage.
Scientists from the Monell Center report that functional olfactory receptors, the sensors that detect odors in the nose, are also present in human taste cells found on the tongue. The findings suggest that interactions between the senses of smell and taste, the primary components of food flavor, may begin on the tongue and not in the brain, as previously thought.
There is now further evidence that a drug that is effective in treating the rare muscle-wasting disease spinal muscular atrophy (SMA) early in life may be associated with improvement in older children, according to a study published in the April 24, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
When you eat something super tasty, ever wonder why you really don't want to stop even though you know you've eaten enough? Scientists at the UNC School of Medicine may have found the reason. In lab experiments, UNC's Thomas Kash and colleagues discovered a specific network of cellular communication emanating from the emotion-processing region of the brain, motivating mice to keep eating tasty food even though their basic energy needs had been met.
