 According to Dhar, et al (2010), dyslexics show:

: Decreased interhemispheric asymmetry in delta activity across the hemispheres during the performance of a visuo-spatial attention tasks, providing evidence of poor interhemispheric resting network communication for dyslexics.

; Decreased interhemispheric coherence of 8.5 Hz in the central–parietal cortex during the performance of a visuo-spatial attention task, indicating less efficient collaboration between hemispheres in dyslexics. 

; Increased interhemispehric asymmetry of beta activity in the pre-frontal cortex during performance of a visuo-spatial attention task, indicating poor right and left hemispheric communication in executive tasks in dyslexics.

; Increased interhemispheric coherence of 4-7 Hz for dyslexics compared to controls in the central–parietal cortex during the performance of a visuo-spatial attention task, providing further support for dulled collaboration between hemispheres in dyslexics.
