Autism may arise from brain’s response to early disturbances
Autism is not a developmental disorder, but rather the brain’s adaptive response to early genetic or environmental disturbances, says Mark Johnson.

Executive confusion
Among siblings of children with autism, those with better prefrontal cortex functioning — observable as relatively strong executive functions for their age — are better able to compensate for atypicalities in other brain systems early in life, and are therefore less likely to receive a diagnosis of autism later in their development, argues Mark H. Johnson.

To persist, memories surf molecular waves from thalamus to cortex
During the later stages of learning, the mouse brain progressively activates transcriptional regulators that drive memory consolidation.

Sex hormone boosts female rats’ sensitivity to unexpected rewards
During the high-estradiol stages of their estrus cycle, female rats learn faster than they do during other stages—and than male rats overall—thanks to a boost in their dopaminergic response to reward, a new study suggests.
