MIRROR AGNOSIA

  • Mirror agnosia is the inability to differentiate between real and reflected objects, to mentally rotate objects, and to perform line orientation tasks. 

  • It results from lesions of either parietal lobe near the posterior angular gyrus/superior temporal gyrus (the temporo-parieto-occipital) junction, and affects both sides of the body

  • Patients with mirror agnosia are aware of the mirror, but cannot correct their behavior even after they have been shown that the real location of the object; they always believe the object to be behind or in the mirror itself and reach for it accordingly.

  • Retinotopic and body-centered coordinate mapping controlled by the parietal lobe is thought to be the underlying cause of this disorder.
