Homology, neurogenetic imprecision, and lesional complexity

Abstract

The two commentaries appear supportive of the target article. Ujhelyi's commentary can be complemented with recent evidence supporting continuity of language and cognitive evolution in hominids. Gow & Rodkin's caveats regarding “pathonormal inference” and the single-case methodology are discussed from a developmental neurobiological perspective. Early structural brain lesion and developmental disorders can serve as pathological models of normal neurofunctional variability resulting from neurodevelopmental imprecision. A final point concerns the advantages of integrating multiple structural and functional imaging modalities in neuropsychological studies.
