Time perception problems may explain autism symptoms
Individuals with autism have trouble perceiving the passage of time, and pairing sights and sounds that happen simultaneously, according to two new studies.

Social interactions not rewarding for children with autism
Children with autism have abnormally low brain activity in the ‘reward center’ of the brain when given money or shown a happy face, according to a study in Autism Research. These are the first imaging data to support the notion that children with autism derive less pleasure from social interactions compared with their healthy peers.

Flu triggers schizophrenia-like features in monkeys
Babies born to rhesus monkeys infected with the flu virus during pregnancy have significantly smaller brains than normal, and other brain abnormalities seen in schizophrenia, researchers have found. The study, published last month in Biological Psychiatry, provides the first evidence in non-human primates linking flu infection to a higher risk of schizophrenia.

Faulty connectivity found in mouse model of schizophrenia
Mice engineered to carry a well-known risk factor for schizophrenia show disruptions in the connections between two brain regions that coordinate memory and learning. And these disruptions directly cause problems with working memory — the ability to actively hold information and to recall that information to make a decision, according to a study published in Nature.

Autism not a fundamental problem of attention, study says
Toddlers with autism pay less attention to faces than do healthy controls, but both groups give equal attention to objects, according to a study published in the Archives of General Psychiatry. The findings challenge the idea that individuals with autism have a generalized problem with attention, suggesting instead that they struggle with attending specifically to social stimuli, researchers say.

Worms help untangle brain structure/function mystery
The synaptic connectome of most animals bears little resemblance to functional brain maps, but it can still predict neuronal activity, according to two preprints that tackle the puzzle in C. elegans.

Microglia nurture young interneurons
The immune cells secrete a growth factor that “sets the supply of GABAergic interneurons in the developing brain.”
