    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.
