Study unravels microscopic mysteries in the brains of C. elegans

It's the small pieces that make the big picture, and in this case, the pieces can't be seen by the naked eye. New research at the Okinawa Institute of Science and Technology Graduate Universit used microscopy techniques to piece together the brain of the millimeter-long Caenorhabditis elegans, revealing that their neurons fire action potentials - a spike in voltage due to neurons sending sensory information in the cell membrane.

Research on mosaic embryos gives new hope to people seeking infertility treatments

Not every embryo contains 46 perfect chromosomes. Some have more, others have fewer. The result is a common abnormality known as aneuploidy, which occurs in as many as 80 percent of human embryos.

Maternal interactions influence infant brain’s ability to detect, respond to angry vocalizations

The same brain network that adults use when they hear angry vocalizations is at work in infants as young as six months old, an effect that is strongest in infants whose mothers spend the most time controlling their behavior, according to a new study in the open-access journal PLOS ONE by Chen Zhao of the University of Manchester, UK, and colleagues.

Many genes contribute to risk for Tourette's syndrome, genetic study shows

A meta-analysis of multiple studies into the genetic background of Tourette's syndrome (TS) - a neurodevelopmental disorder characterized by chronic involuntary motor and vocal tics - finds that variants in hundreds of genes, working in combination, contribute to the development of the syndrome and suggests that Tourette's is part of a continuous spectrum of tic disorders, ranging from mild, sometimes transient tics to severe cases that can include psychiatric symptoms.
