The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Study explains exactly how exposure to lead during brain development produces learning deficits

A study of young adult rats by researchers from the Johns Hopkins Bloomberg School of Public Health provides evidence that explains exactly how exposure to lead during brain development produces learning deficits.

Infants understand other people's emotional states at a very young age

Little children never cease to amaze. University of Washington researchers have found that 18-month-old toddlers engage in what they call "emotional eavesdropping" by listening and watching emotional reactions directed by one adult to another and then using this emotional information to shape their own behavior.

Stem cell therapy shows promise for degenerative diseases of the eye

For the millions of Americans whose vision is slowly ebbing due to degenerative diseases of the eye, the lowly neural progenitor cell may be riding to the rescue.

Self-regulation plays major role in early child achievement

Although intelligence is generally thought to play a key role in children's early academic achievement, aspects of children's self-regulation abilities, including the ability to alternately shift and focus attention and to inhibit impulsive responding--are uniquely related to early academic success and account for greater variation in early academic progress than do measures of intelligence.

Environmental contamination could affect the evolution of wildlife through changes in mating behavior

Female rats avoid males whose great-grandfathers were exposed to a common fruit crop fungicide, preferring instead males whose ancestors were uncontaminated, researchers from The University of Texas at Austin have discovered.
