Table 1. Cortical activation differences between autism and control groups in four major fMRI studies utilizing the Embedded Figures Task to examine visuospatial processing..

Areas in which the control group showed more activation than the autism group
Study	Cortical Activation	General Function of Cortical Region, Relevant to EFT Performance
Ring et al. [23]	Prefrontal cortical areas	Executive function
Damarla et al. [24]	Left dorsolateral prefrontal cortex	Executive function
	Left superior medial frontal gyrus	Executive function
	Left inferior parietal areas	Sensory information interpretation
Manjaly et al. [25]	Left parietal areas	Sensory information integration
	Left premotor areas	Planning movement
Lee et al. [26]	Left dorsolateral prefrontal	Executive function, Verbal strategy
	Left medial premotor	Planning movement
	Left dorsal premotor regions	Motor responses, Eye movement
	Bilateral parietal and occipital cortices	Visual working memory
	Bilateral ventral temporal	Visuospatial processing
Areas in which the autism group showed more activation than the control group
Study	Cortical Activation	General Function of Cortical Region, Relevant to EFT Performance
Ring et al. [23]	Ventral occipitotemporal regions	Visuospatial processing
Damarla et al. [24]	Bilateral superior parietal region extending to inferior parietal and right occipital	Visuospatial processing
Manjaly et al. [25]	Right primary visual cortex	Visuospatial processing
	Bilateral extrastraite area	Visuospatial processing
Lee et al. [26]	Dorsal premotor regions	Planning movement
	Left superior parietal	Visuospatial processing
	Right occipital regions	Visuospatial processing
