Pötzl’s syndrome

a form of pure alexia associated with visual field defects and disturbances of the color sense. The syndrome is believed to be the result of a lesion in the medullary layer of the lingual gyrus of the dominant hemisphere of the brain, with damage to the corpus callosum. [Otto Pötzl]

nonadditive

adj. describing values or measurements that cannot be meaningfully summarized through addition because the resulting total does not correctly reflect the underlying properties of and associations between the component values. For example, if two variables a and b interact to influence another variable y, the addition of the separate effects of a and b will not equal the total effect since the contribution of the interaction needs to be included. Compare additive.
