The CODAM model of attention and consciousness

An engineering approach to attention and motor response is presented, culminating in the CODAM model of consciousness. Support for the presence of several of the relevant modules is discussed from data from a range of experimental paradigms. Two particular paradigms are explored in greater depth. CODAM's relation to other neural approaches to consciousness is discussed in the next section. The paper concludes with a discussion of open questions, and of experiments to search further for the critical signals of CODAM.
