A new study supports the view that songbirds offer a good model to study speech learning in autistic children.

The brain areas involved in mice’s ultrasonic vocalizations may not be the same as those that govern human speech.

A comprehensive review has found no scientific basis for a controversial technique that supposedly helps autistic people communicate.
