Document Summary

Lack of coordination among limb/ body segments superior parietal lobule (spl) area 5 & 7 intraparietal sulcus (ips) inferior parietal lobule (ipl: parietal association cortex. 3 main parts dorsal stream visual control of motor output (spatial, vision pathway) absolute metrics (e. g how far one must spread fingers to grasp obj) Unconscious leads to parietal lobe ventral stream object recognition pathway relational metrics (e. g compare 2 obj) long term representation. M-ganglion cells: large, conduct fast, sensitive to motion, contrast but not colour, less acuity unable to recognize obj simultaneously dorsal stream. P-ganglion cells: smaller, slower, sensitive to colour, high visual acuity (spatial recognition) ventral stream both project to lgn (thalamus) Difficulty copying/drawing/writing because they can"t see the end of the pen and what is on the paper at the same time. Spatial disorientation: unable to recogn spatial properties of obj (e. g. distance and size) Balint"s syndrome visumotor and visuospatial disorder bilateral damage to ppc.
