The architecture of brain, consciousness, and behavioral processes is shown to be formally similar in that all three may be conceived and depicted as Petri net patterned processes structured by a series of elements occurring or becoming active in stochastic succession, in parallel, with different rhythms of temporal iteration, and with a distinct qualitative manifestation in the spatiotemporal domain. A patterned process theory is derived from the isomorphic features of the models and contrasted with connectionist, dynamic system notions. This empirically derived formulation is considered to be optimally compatible with the dual aspect theory in that the foundation of the diverse aspects would be a highly structured and dynamic process, the psychophysical neutral "ground" of mind and matter posed (but not properly determined) by dual aspect and neutral monist theories. It is methodologically sound to approach each one of these processes with specific tools and to establish concurrences in real time between them at the organismic level of analysis. Such intra-level and inter-perspective correlations could eventually constitute psychophysical bridge-laws. A mature psychology of consciousness is necessary to situate and verify the bridges required by a genuine mind-body science.
The mind-body problem: an interdisciplinary domain among brain, cognitive, and behavioral sciencesAt the present state of development of knowledge and understanding it seems that a "transparent" theory about the nature or even about the gross neural correlates of consciousness is a long way ahead. This is not only due to strenuous problems with the concept and recording of consciousness, with all the ontological mind-body theses, or with the still elementary knowledge about higher brain functions. Thus, despite the advent of cognitive science and other integrative attempts, philosophy of mind endeavors and scientific modeling or theorizing still belong to two different cultures. Fortunately, some philosophers (e.g. Churchland, 1995;Dennett, 1991;Flanagan, 1992;Hardcastle, 1994) 180 JOSÉ-LUIS DfAZ blindsight, memory, dream research), in behavioral science (meaningful vocal signals, tactic deception in non-human primates), or in neural computation (neural network models of cognitive capacities associated with consciousness). Their efforts point to the interdisciplinary direction sorely needed on the way towards deciphering the difficult puzzle concerning the nature of consciousness.Time seems ripe for "robust" theories about the connection between brain, consciousness and behavior to take shape. In order to be considered robust, such psychophysical or psychobiological theories should derive from two complementary sources: a well-grounded mind-body ontology and the elaboration of pertinent empirical models from current science (Diaz, 1995). This dual enterprise is difficult enough, but not harder than the resulting task of relating both sets of concepts in a meaningful way. There are rhetorical, methodological, and epistemological br...
