Electrical signals generated by dendrites, the branches of neurons that receive information from neighboring cells, may help neurons tune their responses to stimuli, according to a study published 7 November in Nature.
FOXP2, a language gene that is linked to autism, may regulate active connections between neurons by controlling the levels of a protein called SRPX2, according to a study published 22 November in Science.
People with autism show differences from controls in the levels of microRNAs, small noncoding bits of RNA, in the social and sound-processing parts of the brain. Unpublished results from the postmortem study were presented Wednesday at the 2013 Society for Neuroscience annual meeting in San Diego.
A new technique allows researchers to track the movement of a molecule along a single neuron’s projections. The technique, adapted for zebrafish, was presented Monday at the 2013 Society for Neuroscience annual meeting in San Diego.
MeCP2, the gene associated with Rett syndrome, has widely variable effects on mouse brains depending on the mutation it carries, according to unpublished results presented Tuesday at the 2013 Society for Neuroscience annual meeting in San Diego.
The branching patterns of excitatory neurons in people with Williams syndrome are roughly the opposite of the patterns seen normally, according to unpublished results from a small study presented Monday at the 2013 Society for Neuroscience annual meeting in San Diego.
Emerging evidence indicates that microglia, the brain’s immune cells, are altered in some individuals with autism, raising questions about their role in brain development, says Beth Stevens.
Researchers have added two new candidates to the arsenal of compounds that alleviate both the behavioral and molecular hallmarks of fragile X syndrome in mice that model the disorder. A third candidate, minocycline, improves some symptoms in children with the disorder.
Show an image of a neuron to NEMO, a new free software tool, and it will trace the neuron’s shape and detail the length, breadth and number of its branches, scientists who designed the software reported 14 February in Frontiers in Neuroinformatics.
A number of autism risk factors converge on one cellular pathway: abnormal remodeling of the cell’s structural systems through the signaling protein Rho, says SFARI’s associate director for research, Alan Packer.
