Researchers have developed a new way to perform high-resolution microscopy in a moving, changing organism, they reported in November in Nature Biotechnology. They used the method to follow the development of a live embryo and its brain.

A small, customized magnetoencephalography device records signals in children’s brains better than the typical adult-sized machine does, reports a study published 8 October in Molecular Autism.

Skin cells taken from mice with an autism-linked mutation and transformed directly into neurons have the same properties as neurons from the brains of these mice. The study, published 8 October in Proceedings of the National Academy of Sciences, validates an efficient technique to study disease-linked mutations.

A tiny fiber-optic probe inserted into the reward center of the mouse brain monitors how the mouse feels about meeting a peer — or a golf ball. The unpublished technique was presented last week at the 2013 Society for Neuroscience annual meeting in San Diego.

Cells extracted from baby teeth, which fall out on their own, may be better suited than skin cells for making induced neurons to use in autism research, suggests a study published 3 October in PLoS One.

Researchers have mined the medical records of more than 100 million people and found close to 3,000 associations between single-gene diseases, such as cystic fibrosis, and complex genetic disorders such as autism. The results were published 26 September in Cell.

Researchers have coaxed human stem cells to develop into simplified mini-brains, with regions resembling discrete brain structures, they reported 19 September in Nature.

A new method of genetic analysis allows researchers to identify regions that are identical on both copies of a chromosome, according to a study published 20 September in Molecular Cytogenetics.

Researchers have developed software that can automatically track and catalog the behavior of up to four mice at once, according to a study published 16 September in PLoS One.

Researchers have optimized the production from stem cells of large numbers of a subtype of neurons involved in cognitive function. The technique, published 20 August in Translational Psychiatry, could generate enough neurons for large-scale screening of drugs.
