Visual print tuning deficits in dyslexic adolescents under minimized phonological demands

► Adolescent dyslexics studied at a critical developmental stage for fluent reading. ► A task that targets bottom-up print processing and minimizes phonological confounds. ► Typical readers' ventral occipitotemporal cortex is tuned to letter processing. ► Dyslexic readers fail to show bottom-up tuning even without phonological challenge.
