Document Summary

Contralateral neglect/ hemispatial neglect or unilateral neglect right inferior parietal lesions. Requires all 4 symptoms finger agnosia (no knowledge of what finger), right- Is it really a problem? very rare left confusion, agraphia, and acalculia. It isn"t due to weakness, inability to move, abnormal muscle tone/posture, Due to lesions in places in the brain having to do with motor skills. Loss of knowing the sequence of movements need to be done (cannot order movements in the correct way) Not direct lesion in parietal lobe, it just has to do with the ordering. Spatial cognition right side: ability to use topographic info (map to a place) is tampered with left side: cannot make mental images. Frontal lobe fifth-third of neocortex (a lot of brain) Last part of brain to develop, synaptic pruning and synaptogenesis and myelination take longer in this lobe total efficient transfer here doesn"t occur till we are in our 20s.
