How certain neural mechanisms momentarily endow with the subjective awareness percepts and affects represented elsewhere is more likely to be clarified when structures essential to Mc are identified. The loss of C with bilateral thalmic lesions involving the intralaminar nuclei contrasts with retention of C after large cortical ablations depriving C of specific contents. A role of ILN in the perception of primitive sensations is suggested by their afference of directly ascending pathways. A role for ILN in awareness of cortical (...) activity is suggested by their widespread afference from cortex, a property shared with striatum. A role for ILN in volition is suggested by their heavy projection to striatum. Unlike striatum, ILN also project widely to almost all neocortex, enabling an effect on ideation; this last property is in common with other structures but none of them has the same direct cortical afference. And passage through the reticular nucleus of ILN efferents to cortex could impact the attention-selective action of nRt. It is suggested that the quickest route to a better understanding of C involves more intensive study of ILN. No other structure seems, in the light of our current knowledge, a more likely site for Mc. (shrink)

This paper argues for the importance of inner speech in a proper understanding of the structure of human conscious experience. It reviews one recent attempt to build a model of inner speech based on a grammaticization model (Steels, 2003) and compares it with a self-regulation model here proposed. This latter model is located within the broader literature on the role of language in cognition and the inner voice in consciousness. I argue that this role is not limited to checking the (...) grammatical correctness of prospective utterances before they are spoken. Rather, it is a more broadly activity-structuring role, regulating and shaping the ongoing shape of human activity in the world. Through linking inner speech to the control of attention, I argue that the study of the functional role of inner speech should be a central area of analysis in our attempt to understand the development and qualitative character of human consciousness and that modelling can play a central role in that understanding.

Social cognition, cognitive neuroscience, and neuroethics have reached a synthesis of late, but some troubling features are present. The neuroscience that currently dominates the study of social cognition is exclusively cognitive neuroscience, as contrasted with the cellular and increasingly molecular emphasis that has gripped mainstream neuroscience over the past three decades. Furthermore, the recent field of molecular and cellular cognition has begun to unravel some molecular mechanisms involved in social cognition, especially pertaining to the consolidation of memories of particular conspecific (...) organisms. Some new experimental techniques for positive interventions into these hypothesized mechanisms offer opportunities for establishing direct causal linkages between intra-neuronal molecular events and the behaviors used to measure social cognitive phenomena. Predicted results from an experiment described below also cast doubt on the application of the “extended mind” approach from recent cognitive science to ground the neuroscience of social cognition. Since neuroethics relies heavily on our best neuroscience of social cognition, that field may soon need to extend its attention beyond cognitive neuroscience, and into neuroscience’s cellular and molecular mainstream.

Whenever I speak on the topic of dreams, I mention a very unusual of dream the lucid dream in which the dreamer knows he is dreaming and feels fully conscious difficulties in defining states of consciousness, I always ask weather anyone has the slightest doubt that he is awake that is in a normal state of consciouness at the moment; I have never found anyone who had difficulty in making this destinction.
