Blocking protein helps cognition in mice
Brain cells called microglia serve as the brain’s garbage crew, scarfing up bits of cellular debris. But their underperformance in aging brains contributes to neurodegeneration. Now, a possible workaround?…
Possible role of deep brain structure in concussion
Through a combination of biometric tracking, simulated modeling and medical imaging, Stanford researchers have detailed how hits to the side of the head may cause concussion.
Rewards warp brain’s spatial maps
The brain creates spatial maps to help animals, including humans, navigate through different environments. But even in the same environment, Stanford scientists have shown, the promise of a reward redraws the map.
Quickly forecasting post-stroke dementia
Stanford researchers have found that transient changes in the numbers and activation levels of a handful of circulating immune cell types can predict the likelihood of dementia one year after a stroke.
Brain response to mom’s voice differs in autism
Mom’s voice causes a strong response in the brains of typically developing children, but the response is weaker in children with autism, a Stanford study has demonstrated.
Hard-wired male/female brain differences
The discovery, by Stanford researchers, of neurons that drive mice’s innate ability to identify the sex of other mice highlights the importance of biological influences on sex-specific behaviors.
Key brain-cell type probed
Studying human oligodendrocytes, which provide insulation for nerve cells, has been challenging. But a new way of generating stem-cell-derived, three-dimensional brain-cell cultures is paying off.
Using worms to investigate drugs
Humans have relied on plants for millennia to treat a variety of neurological ailments. Now, researchers are using microscopic worms to better understand how plant molecules shape behavior — and perhaps develop better new drugs.
Bundle of cells produces pain aversion
Pain sensation and the emotional experience of pain are not the same, and now, in mice, scientists at Stanford have found the neurons responsible for the latter.
Social- versus food-related brain cells
Researchers at Stanford demonstrated that direct stimulation of fewer than two dozen neurons linked to social interaction was enough to suppress a mouse’s drive to feed itself.
