Animals’ brain activity ‘syncs’ during social interactions
by
•Egyptian fruit bats and mice, respectively, can ‘sync’ brainwaves in social situations. The synchronization of neural activity in the brains of human conversation partners has been shown previously, as a …read more Source:: Science
Brains of blind people adapt to sharpen sense of hearing, study shows
by
•Research uses functional MRI to identify two differences in the brains of blind individuals — differences that might be responsible for their abilities to make better use of auditory information. …read more Source:: Science
Experimental PET scan detects abnormal tau protein in brains of living former NFL players
by
•Using an experimental positron emission tomography (PET) scan, researchers have found elevated amounts of abnormal tau protein in brain regions affected by chronic traumatic encephalopathy (CTE) in a small group …read more Source:: Science
How to rapidly image entire brains at nanoscale resolution
by
•A powerful new technique combines expansion microscopy with lattice light-sheet microscopy for nanoscale imaging of fly and mouse neuronal circuits and their molecular constituents that’s roughly 1,000 times faster than …read more Source:: Science
Bees can count with just four ‘nerve cells’ in their brains
by
•Bees can solve seemingly clever counting tasks with very small numbers of nerve cells in their brains, according to researchers. …read more Source:: Science
Evidence of restored vision in rats following cell transplant
by
•Researchers have discovered that neurons located in the vision centers of the brains of blind rats functioned normally following fetal retina cell transplants, indicating the successful restoration of vision. …read more Source:: Science
Pain response in babies’ brains controlled in ‘similar way to adults’
by
•Researchers have identified the neural network that helps control babies’ brain activity in response to pain in a similar way to adults. Their findings build on their previous study from …read more Source:: Science
Prolonged exposure to air pollution leads to genetic changes in rat brains, study finds
by
•Prolonged exposure to particulate matter in air pollution in the Los Angeles Basin triggered inflammation and the appearance of cancer-related genes in the brains of rats, a new study has …read more Source:: Science
Alzheimer’s disease reversed in mouse model
by
•Researchers have found that gradually depleting an enzyme called BACE1 completely reverses the formation of amyloid plaques in the brains of mice with Alzheimer’s disease, thereby improving the animals’ cognitive …read more Source:: Science
