ABSTRACT
This chapter aims to recapitulate the contribution of neuropsychology to the study of consciousness. An idea of the prospects and difficulties facing any neurological theory of consciousness may be given by briefly reviewing a few alternative proposals and the lively discussion stirred by the most one. The huge expanse of the busy neural network in which representational activity is implemented and which is beyond any realistic hope of panoramic assessment by neurophysiological means. Phenomenal experience, according to this hour-glass model of mental activity, might be locally sustained at its neck: the subicular area. Alternatively, it might be the result of feedback from this area to those areas on the activity of which the subiculum bases its match/mismatch decisions. Functional implications are much less obvious as regards an individual’s mental activity. The instability of endogenous clusters of neural representational activity.
