A new study suggests that sensory issues associated with autism may be caused by fluctuating neuronal noise in the brain. This study found that variability in the activity of individual neurons in a mouse model of fragile X syndrome, a leading cause of autism, mapped to fluctuations in the levels of noise in the brain. The fluctuations in noise in animals modeling fragile X syndrome lead to less reliable processing of sensory information. The study also found that disorderly brain waves, which have been linked to autism, may contribute to sensory issues. This research provides insight into the complexity of sensory problems in autism and opens up new possibilities for treatment.
