Temple Grandin, perhaps the world’s most famous person with autism, has exceptional nonverbal intelligence and spatial memory, and her brain has a host of structural and functional differences compared with the brains of controls, according to a presentation Saturday at the 2012 Society for Neuroscience annual meeting in New Orleans.
Astrocytes, star-shaped brain cells that support neurons, may be needed for mice to learn motor skills, according to unpublished research presented Saturday at the 2012 Society for Neuroscience annual meeting in New Orleans.
Star-shaped cells in the brain wrap themselves around synapses, the junctions between neurons, and influence their development. In a video interview Saturday at the 2012 Society for Neuroscience annual meeting in New Orleans, Ben Barres discusses the possible role of astrocytes in autism.
After nine long years, the Society for Neuroscience annual meeting is returning to New Orleans. And SFARI.org’s reporters are ready to deliver the best advances in autism research that emerge.
Mice that model Angelman syndrome or have a duplication of the 15q11-13 chromosomal region have aberrant brain levels of the chemical messenger serotonin, according to a study published 16 August in PLoS One.
A new mouse model provides the first molecular link between the known autism risk gene PTEN and the mitochondrial dysfunction sometimes seen in the disorder. Mice with half the normal amount of PTEN protein in their brains have social deficits reminiscent of autism and faulty mitochondria, according to a study published 10 August in PLoS One.
The so-called ‘spiny mouse’ species has a gestational period twice as long as that of typical laboratory mice. This makes them good models for studying the link between prenatal exposure and autism risk, according to a study published 29 August in Brain, Behavior and Immunity.
An atypical response to sensory stimuli, such as smells and sounds, may be a core feature of autism, suggest two studies published in the past few months.
Which test a clinician uses to diagnose a child with autism may determine whether that child meets the criteria proposed in the newest version of the Diagnostic and Statistical Manual of Mental Disorders.
RNA editing, which creates multiple forms of a protein, is common among proteins involved in neuronal signaling, and may be abnormal in people with autism, according to a study published 7 August in Molecular Psychiatry.
