Study sheds light on how autism manifests in the brains of girls
New research has shed light on how autism-spectrum disorder (ASD) manifests in the brains of girls, prompting the scientists to warn that conclusions drawn from studies conducted primarily in boys should not be assumed to hold true for girls.
The researchers discovered that there is a significant difference in the genes and genetic burden that underpin the condition in girls and boys. They also identified specific ways the brains of girls with ASD respond differently to social cues such as facial expressions and gestures than do those of girls without ASD.

How Your Brain Decides To Put in Effort
Researchers have clear visual evidence that a region of the human brain known as the ventral striatum kicks in during decision-making to weigh the costs versus the benefits of making a physical effort.
The research gives the first detailed view of ventral striatum activity during three phases of effort-based decision-making the anticipation of initiating an effort, the actual execution of the effort, and the reward, or outcome, of the effort.
