The right and left sides of the brain look similar, but have different functions. We can see this by measuring blood flow to the brain when people do language activities, such as naming pictures or generating words. In most people, the left side has more blood flow than the right during language activities, but this can vary. We are investigating whether people with neurodevelopmental conditions affecting language, reading and communication are more likely to use different sides of the brain for different aspects of language processing.

We are looking for student volunteers aged 18-30 years, both with a recognized neurodevelopmental condition, such as dyslexia or autism spectrum disorder, and volunteers who are not affected by such conditions. Participating in the study involves two testing sessions on different days, each lasting around 2 hours. These sessions would include language and literacy assessments, and a safe and non-invasive ultrasound procedure (Transcranial Doppler Ultrasound) that measures blood flow to the brain during language tasks.
