The problems people with autism have with memory formation, higher-level thinking and social interactions may be partially attributable to the activity of receptors inside brain cells, researchers at Washington University School of Medicine in St. Louis have learned.

Adult humans continuously produce new neurons in the striatum, a brain region involved in motor control and cognitive functions, and these neurons could play an important role in recovery from stroke and possibly finding new treatments for neurodegenerative disorders, according to a study published by Cell Press February 20th in the journal Cell. To detect the birth of new neurons in the striatum, the authors used a method that measures carbon-14 found in human DNA as a result of above-ground nuclear testing more than half a century ago. The findings reveal a surprise finding of new neurons in a human brain structure where they haven't been previously described. The discovery may open up new avenues to treat diseases and disorders that affect the striatum.

New research suggests a surprising degree of similarity in the organization of regions of the brain that control language and complex thought processes in humans and monkeys. The study, publishing online January 28 in the Cell Press journal Neuron, also revealed some key differences. The findings may provide valuable insights into the evolutionary processes that established our ties to other primates but also made us distinctly human.

Suppose you heard the sound of skidding tires, followed by a car crash. The next time you heard such a skid, you might cringe in fear, expecting a crash to follow — suggesting that somehow, your brain had linked those two memories so that a fairly innocuous sound provokes dread.

Researchers at Penn Medicine have generated a brain development index from MRI scans that captures the complex patterns of maturation during normal brain development. This index will allow clinicians and researchers for the first time to detect subtle, yet potentially critical early signs of deviation from normal development during late childhood to early adult.

It might be true that people have a harder time controlling themselves when they are tired at the end of the day, but that doesn't mean that self-control is a limited resource, say authors in the Cell Press publication Trends in Cognitive Sciences on January 15th. The trick to fighting that couch potato urge is for you (or your kids) to find pleasure in productive activities.
