  • * Partial involvement.

  • The numbers represent the total number of cases with involvement in each anatomical sector. G1, asomatognosia; G1-SA, asomatognosia without delusions/confabulation; G1-SP, asomatognosia with delusions/confabulation; G2, non-asomatognosia with hemiplegia and hemispatial neglect; G3, hemiplegia only. BA, Brodmann areas; G1, 13 cases; G1-SA, six cases; G1-SP, seven cases; G2, seven cases; G3, six cases.
