Document Summary

Visual impairments after parietal lesions can be characterized as visuomotor or orientational. Visual impairments after temporal lesions affect object recognition and naming. * lesions to the ppl can cause optic ataxia - or an inability to guide the hand toward an object using visual information. Behavioral testing: using the divided visual field paradigm scientists are able to measure task performance when visual stimuli are present on the left or right visual hemispheres. Spreading depression: the technique such as wada test allows neuropsychological test that is performed while half of the brain is asleep or frozen . Fmri (functional magnetic resonance imaging): testing behavioral, perception or cognition by presenting stimuli and monitoring brain"s response using visual. Pet (positron emission tomography): with the use of radioactive drug (i. e. tracer), brain asymmetry can be seen when a behavior/ perceptual/ cognitive task or event is seen or evoked based on the stimuli present or task assigned.
