Neural correlates of sentence reading in children with reading difficulties

Panagiotis G. Simos, Roozbeh Rezaie, Jack M. Fletcher, Jenifer Juranek, Andrew C. Papanicolaou
2011 NeuroReport  
In contrast to word-level skills, the neural basis of sentence comprehension in children with reading difficulties is not well understood. Using magnetic source imaging, we investigated the spatiotemporal dynamics of regional activity associated with silent passage reading in nonimpaired and students with reading difficulties. The latter exhibited underactivation of the temporoparietal and visual cortices, bilaterally, and of the left posterior cingulate region. Late activity in left

These findings support the notion that reduced temporoparietal activation during word reading in context, is a hallmark of the functional deficit in reading disability. NeuroReport

Time course of electromagnetic activity associated with detection of rare events

Roozbeh Rezaie, Panagiotis G. Simos, Andrew C. Papanicolaou, Eduardo M. Castillo, Dana C. Moser, Antony D. Passaro, Jack M. Fletcher
2011 NeuroReport  
The neural origins of the cortical response to rare sensory events remain poorly understood. Using simultaneous event-related potentials and magnetic resonance imaging, we investigated the anatomical profile of regional activity at various processing stages during performance of auditory and visual variants of an oddball paradigm. The earliest rarity-detection response was found in sensory-specific cortices, rapidly spreading to tertiary association areas, mesial temporal and frontal cortices
