Abstract

This chapter focuses on the neurology of naming and the retrieval of words for nonunique concrete entities as well as for unique concrete entities. Preliminary evidence for retrieval of words for actions is discussed in the chapter. The chapter presents a study which proposes that the retrieval of word-form information, on the basis of which naming can occur, depends on the transient reactivation of the phonemic and morphologic structure of given words within the appropriate early sensory cortices and motor-related structures. In this study, the neural sites identified are seen as clusters of neuron ensembles that hold dispositional records for the transient reconstruction of word forms, in appropriate sensory and motor structures, when the processing of the concepts of the corresponding entities activates those ensembles. Some of these neuron ensembles operate as intermediaries between the neural sites that subserve conceptual structure, and the neural sites in which a word form can be transiently reconstructed. The findings in the study support the idea that in addition to the separation of the neural systems that support the retrieval of concepts for entities belonging to varied categories, there is a parallel regionalization for the systems that support the retrieval of the word forms corresponding to those entities.
