74:(denial or lack of awareness) of the paralysis. The link between somatoparaphrenia and paralysis has been documented in many clinical cases, and while the question arises as to whether paralysis is necessary for somatoparaphrenia to occur, it has been confirmed that anosognosia is not necessary, since cases of somatoparaphrenia and paralysis with no anosognosia have been documented.
135:, the thalamus and the white matter connecting the thalamus to the cortex may also play a significant role in the development of somatoparaphrenia. It has also been suggested that involvement of deep cortical and subcortical grey structures of the temporal lobe may contribute to reduce the sense of familiarity experienced by somatoparaphrenic patients for their paralyzed limb.

The main manifestation of somatoparaphrenia is the feeling of disownership of the contralesional body; the belief that contralesional body parts do not belong to them but to another person. Reinstatement of ownership by third-person perspective does not permanently abolish somatoparaphrenia
