Descrizione

The prefrontal cortex has shown major evolutionary changes even since the brains of the great apes. It is generally accepted to be the structure most critical for the organisation of abstract human thought. Yet we have a very poor understanding of to what extent it contains specialised subsystems and if so what the functions of those subsystems are. In this presentation it will be argued that overall the function of the system is to confront novel situations. It will also be argued that the system is relatively internally modular containing component systems which have rather abstract functions, such as the controlling of the generation of new strategies and the active checking of non-routine actions. Evidence will be reviewed, mainly from neuropsychological studies of neurological patients, to support the idea of the internal modularity of the system. For instance, it will be argued that strategy-generation and the active checking of non-routine actions are partially localised to the left and right lateral prefrontal cortex respectively. The studies to be described include ones using a variety of types of experimental paradigms such as attentional and reaction time tasks, problem-solving and memory retrieval. Broad analogies will be drawn with the internal structure of certain symbolic artificial intelligence expert systems programs.
