Zebrafish Study Shows Brain Activity Intensity Drives the Need for SleepNews
The intensity of brain activity during the day, notwithstanding how long we've been awake, appears to increase our need for sleep, according to a new UCL study in zebrafish.
Alzheimer's Risk Gene Impairs Brain's Immune CellsNews
A study carried out with a new human stem cell-derived model reveals that the most prevalent genetic risk factor of Alzheimer's disease (AD), apolipoprotein E4 (APOE4), impairs the function of human brain immune cells, microglia. These findings pave the way for new, effective treatment approaches for AD. The results were published in Stem Cell Reports.
White Matter Connections Could Be the Key to Successful Brain StimulationNews
Tiny changes in the microscopic structure of the human brain may affect how patients respond to an emerging therapy for neurological problems, potentially explaining inconsistencies in treatment efficacy.READ MORE
The ritualized fighting behavior of one ant species is linked to increases in dopamine levels that trigger dramatic physical changes in the ants without affecting their DNA, according to research from North Carolina State University, Arizona State University and the [US] Department of Agriculture.READ MORE
Pinecone or pine nut? Friend or foe? Distinguishing between the two requires that we pay special attention to the telltale characteristics of each. And as it turns out, us humans aren't the only ones up to the task.READ MORE
Mindfulness meditation produces personal experiences that are not readily interpretable by scientists who want to study its psychiatric benefits in the brain. At the 12th Annual International Scientific Conference of the Center for Mindfulness near Boston in April, Brown University researchers described how they've been able to integrate mindfulness experience with hard neuroscience data to advance more rigorous study.READ MORE
When tracking a moving object, the two halves of the human brain operate much like runners successfully passing a baton during a relay race, says a University of Oregon researcher.READ MORE
A variant of the gene KLOTHO is known for its anti-aging effects in people fortunate enough to carry one copy. Now researchers find that it also has benefits when it comes to brain function. The variant appears to lend beneficial cognitive effects by increasing overall levels of klotho in the bloodstream and brain.READ MORE
Children with autism experience deficits in a type of immune cell that protects the body from infection. Called granulocytes, the cells exhibit one-third the capacity to fight infection and protect the body from invasion compared with the same cells in children who are developing normally.READ MORE
Scientists studying the bizarre phenomenon of synaesthesia- best described as a "union of the senses" whereby two or more of the five senses that are normally experienced separately are involuntarily and automatically joined together- have made a new breakthrough in their attempts to understand the condition.READ MORE
Scientists have found that pressure from the fluid surrounding the brain plays a role in maintaining proper eye function, opening a new direction for treating glaucoma- the second leading cause of blindness worldwide.READ MORE
New research suggests that certain types of brain cells may be "picky eaters," seeming to prefer one specific energy source over others. The finding has implications for understanding the cognitive decline seen in aging and degenerative diseases such as Alzheimer's and multiple sclerosis.READ MORE
