Autism is a complex neurodevelopmental disorder, characterized by deficits in social emotional, and language domains, as well as repetitive restrictive behaviors. The vast heterogeneity of the clinical and behavioral symptoms has made it rather difficult to delineate the neural circuitry affiliated with these domains of dysfunction. The current review aims at broadly outlining the latest research into the neurobiology and neural circuitry underlying the core domains of deficits in autism.

However, prior studies from our laboratory have found that processing of unattended auditory deviant tones in the auditory and frontal regions is modulated by top-down attentional demands and resource availability. Whether processing of unattended visual deviant stimuli is altered by the availability of attentional resources has not been established.

- Previous studies indicate that the brain's response to unexpected auditory changes is automatic and reflects how we process sound, regardless of our attention.
- The research involved subjects listening to tone pips while performing visual tracking tasks, finding that brain areas linked to sound processing were activated by unheard pitch changes, with activity varying based on task difficulty.
- The results showed that when the primary task was more challenging, the brain's electrical response to the deviant tones was reduced, suggesting that attention to different tasks can significantly influence how we process unattended sensory information.
Article Synopsis
- New and surprising events are crucial for survival, as they help organisms respond to their environments.
- Researchers investigated how complex tasks affect brain responses to unexpected sounds while participants tracked a moving target with a joystick.
- The study found that as task difficulty increased, the brain's ability to process new auditory information was reduced, suggesting that attention and resources are limited during challenging tasks.
