Description

<p>Clinical neuropsychology has analyzed various symptoms and signs after brain lesions and approached to the brain mechanisms underlying a wide range of cognitive functions. In recent neuropsychology, classical semiology has reconciled with the approaches with the advanced imaging technology (e.g. functional imaging and tractography) and the findings during awake surgery, and neuropsychological theories have shifted from the localizationist models to the neural network models. An acute cognitive dysfunction resulting from a localized lesion is not always long lasting, which reflects redundancy of the neural network that takes part in the corresponding function. The present review aims to reconsider neuropsychological disorders from the viewpoint of hodology focusing on the neural networks of language and spatial attention.</p>
