Russian neurolinguistics post Luria

Authors discuss parts of the lexicon, "Kernel, peripheral and individualistic features". Word fluency did not distinguish aphasia types. Perseverations were more common in anterior groups, semantization index decreased in all groups. Both cortical and subcortical lesions did not change the nominal lexicon, but did change the structure of verbs, with de-individualization. In aphasia more than PD , the individual parts of verbs disappear.

The kernel lexicon is primarily based on the frequency and time of appearance of the words in childhood. Also, personal reflection in the words based on personal scholarship, etc. are common, but these are especially reduced in all groups, ie relatively preserved kernel lexicon but reduced personalized lexicon.

In left handers who speak Russian, conduction and transcortical aphasia is commoner, whereas motor and acoustic-gnostic aphasia is commoner in right handers with left hemisphere lesions.
