To define a correct rehabilitation program for neurological patients who have impairment in these skills, there is a need for simple and cost-effective tools to determine which of the visual-motor system levels of organization are compromised by neurological lesions. In their 1995 book, The Visual Brain in Action (Oxford: Oxford University Press), AD Milner and MA Goodale proposed the existence of two pathways for the processing of visual information, the &ldquo;ventral stream&rdquo; and &ldquo;dorsal stream,&rdquo; that interact in movement planning and programming. Beginning with this model, our study aimed to validate a method to quantify the role of the ventral and dorsal streams in perceptual and visual-motor skills.Subjects and methods: Nineteen right-handed healthy subjects (mean age 22.8 years &plusmn; 3.18) with normal or corrected-to-normal vision were recruited. We proposed that a delayed pointing task, a distance reproduction task, and a delayed anti-pointing task could be used to assess the ventral stream, while the dorsal stream could be evaluated with a grasping task and an immediate pointing task. Performance was recorded and processed with the video-analysis software Dartfish ProSuite.Results: Results showed the expected pattern of predominance of attention for the superior left visual field, predominance of the flexor tone in proximal peri-personal space arm movements, tendency toward overestimation of short distances, and underestimation of long distances.Conclusion: We believe that our method is advantageous as it is simple and easily transported, but needs further testing in neurologically compromised patients.Keywords: dorsal stream, ventral stream, visual-motor skills, rehabilitation, neurological disordersChiappedi MToraldo AMandrini SScarpina FAquino MMagnani FGBejor MDove Medical PressarticleNeurosciences.
