Autotopagnosia, somatopagnosia
Verbal Command: Point to
Examiner
Examiner names a body part, and subjects are instructed to point to that named part
on the examiner.
Visual Cue: Point to Self
Examiner points to body parts on himself, and subjects are required to point to the
homologous part on themselves.
Visual Cue: Point to
Examiner
Examiner points to a body part on the subjects, and they are required to point to the
homologous part on the examiner.
Blindfold Post-Visual Cue:
Point to Self
Same as Study 1c., except subjects are blindfolded after examiner points to himself,
prior to response execution.[11]

• The nondominant inferior parietal lobule is probably a major “store
house” of artistic creativity
• conceptualization is conceived in the VMPFL and the executive part is
operated through the DLFPL.
• The conceptualization at VMPFL is influenced by activity from the
anterior temporal lobe through the uncinate fasciculus and limbic
system pathways
• The latter transfers the concept to the visual brain through the
superior longitudinal fasciculus (SLF), relaying on its path to the
parietal cortex.
