FIGURE 4.

Number of correctly named items as a function of the percentage of ablated neurons in (A) concept buffer (concept_prod), (C) lemma buffer (word_prod), (E) lexeme buffer (phono_prod), and in the connection buffers between (B) the concept and the lemma buffer and between (D) the lemma and lexeme buffer. Statistical comparisons between the dysfunction conditions with the Mann-Whitney-U-test: + p = 0.05; ^∗p < 0.05. The area marked in yellow shows the values of correctly named items within ± 1 standard deviation from the mean of the norm data for the age category 5;6-6;5 of the WWT.
