Removing the fragile X syndrome gene from two brain regions in mice leads to signaling defects but does not produce behavioral deficits, according to a study published in the February issue of Autism Research.
When exposed to irritating noises or images, children with autism show hypersensitivity in brain regions that process sensory information and emotions, according to a study published in November in the Journal of the American Academy of Child and Adolescent Psychiatry.
Studies at the level of neural circuits are needed to better understand the importance of both increased and decreased connectivity between different regions in the autism brain, say John Rubenstein and Vikaas Sohal.
By mapping the brains of not 1 but 27 mouse models of autism, researchers are making sense of the widely divergent structural changes seen in autism brains, they reported Wednesday at the 2013 Society for Neuroscience annual meeting in San Diego.
Three decades of research on anatomical changes in the brains of individuals with autism has yielded few if any consistent patterns. The field needs an overhaul of the methods used, researchers said at a symposium Wednesday at the 2013 Society for Neuroscience annual meeting in San Diego.
Brain regions that help people orient themselves in space and time may also guide their sense of intimacy and hierarchy with another person, according to findings presented Sunday at the 2013 Society for Neuroscience annual meeting in San Diego.
Oxytocin may enhance brain signaling by increasing the strength of the signals and minimizing background noise, according to a study published 4 August in Nature.
