Fragile X proteins involved in proper neuron development

Posted: 10 Jun 2015 01:17 PM PDT

Fragile X syndrome is the most common inherited intellectual disability and the greatest single genetic contributor to autism. Unlocking the mechanisms behind fragile X could make important revelations about the brain. In a new study, researchers show that two proteins implicated in fragile X play a crucial role in the proper development of neurons in mice.

Youth on the autism spectrum overly sensitive to sensory stimuli have brains that react differently

Using functional magnetic resonance imaging, a team of researchers has shown for the first time that children with autism spectrum disorder who are overly sensitive to sensory stimuli have brains that react differently.

Syllables that oscillate in neuronal circuits

Speech, emitted or received, produces an electrical activity in neurons that neuroscientists measure in the form of "cortical oscillations." To understand speech, as for other cognitive or sensory processes, the brain breaks down the information it receives to integrate it and give it a coherent meaning. But researchers could not confirm whether oscillations were signs of neuronal activity, or whether these oscillations played an active role in speech processing. Researchers reached such conclusions after having created a computerized model of neuronal microcircuits, which highlights the crucial role of neuronal oscillations to decode spoken language, independently of speakers' pace or accent.

Decreased social anxiety among young adults who eat fermented foods

Posted: 09 Jun 2015 06:28 AM PDT

A possible connection between fermented foods, which contain probiotics, and social anxiety symptoms, is the focus of recent study. The study is just the first in a series that the researchers have planned to continue exploring the mind-gut connection, including another examination of the data to see whether a correlation exists between fermented food intake and autism symptoms.
