Loss of inhibitory neurons marks autism mouse models
Autism may be the result of faulty wiring that occurs during early brain development, according to two independent studies that looked at the origins of circuit disruption.

Deleting MeCP2, the gene that’s mutated in Rett syndrome, alters both the size and function of neurons in the mouse brain — at least in one brain region, the locus ceruleus — according to a 30 September report in the Journal of Neuroscience.
Genetic analysis of one Belgian family with a history of autism has pinpointed a piece of DNA on chromosome 16, within a segment thought to be missing in about one percent of all cases of autism. The unpublished data was presented on Saturday at the World Congress of Psychiatric Genetics in San Diego.
The molecular defects that cause some cases of autism may arise during the development of neuronal stem cells, according to a new theory bolstered by several independent animal and human studies.
Schizophrenia may be a consequence of neuronal birth gone awry, according to unpublished research presented today at the Society for Neuroscience conference.
