Rejuvenated immune cells can improve clearance of toxic waste from brain

Rejuvenating the immune cells that live in tissues surrounding the brain improves fluid flow and waste clearance from the brain — and may help treat or even prevent neurodegenerative diseases such as Alzheimer’s and Parkinson’s, according to a new stu…

Most detailed map of brain’s memory hub finds connectivity puzzle

An extremely detailed map of the communication links between the hippocampus — the brain’s memory control center — and the rest of the brain has been created. And it may change how we think about human memory.

New biomarker could help diagnose Alzheimer’s disease early

A definitive diagnosis of Alzheimer’s disease (AD) was once only possible after someone had died, but recent biomarker studies have led to the development of imaging and spinal fluid tests for those still living. However, the tests can only monitor sev…

Differences between brains of primates are small but significant, study shows

While the physical differences between humans and non-human primates are quite distinct, a new study reveals their brains may be remarkably similar. And yet, the smallest changes may make big differences in developmental and psychiatric disorders.

Mental landscapes: Seeing in 3D

Many thousands of retinal ganglion cells (RGCs) have to relay signals through the eye’s optic nerve via delicate projections, or axons, to precise locations on both sides of the brain that make visual sense of it all, especially to perceive depth. Some…

Neuronal mechanism involved in the learning of maternal behavior discovered

Various conditions such as postpartum depression or postpartum psychosis can lead to an alteration in maternal behavior and disrupt the mother-child bonding process. A research team has conducted a study in which they were able to identify the neuronal…

How breathing shapes our brain

We breathe to survive. But a breath of fresh air does more than fill our lungs. New research indicates that breathing impacts our emotions, attention and how we can process the outside world.

Researchers identify a molecular mechanism associated with juvenile Parkinson’s

Parkinson’s disease affects 3% of population over 65 years old, and the average age of onset is 60. Regarding juvenile Parkinson, which represents the rest of all Parkison’s cases, the disease begins before 40 years old. Now, a group of researchers has…

Scientists get clearer picture of developing teen brain

Neuroscientists described compelling new evidence of a critical neuroplasticity period in the frontal brain region during adolescence, a time when major mental illnesses such as depression and schizophrenia emerge and risk-taking behavior peaks.
