Donald Hoffman — Quantum Physics of Consciousness
Posted by Dan Breeden in categories: neuroscience, quantum physics
Are quantum events required for consciousness in a very special sense, far beyond the general sense that quantum events are part of all physical systems? What would it take for quantum events, on such a micro-scale, to be relevant for brain function, which operates at the much higher level of neurons and brain circuits? What would it mean?

The Global Workspace Theory of Consciousness
Posted by Dan Breeden in category: neuroscience
Global Workspace Theory (GWT) can be compared to a theater of mind, in which conscious contents resemble a bright spot on the stage of immediate memory, selected by a spotlight of attention under executive guidance. Only the bright spot is conscious; the rest of the theater is dark and unconscious. GWT has been implemented in a number of explicit and testable global workspace models (GWM’s). These specific GW models suggest that conscious experiences recruit widely distributed brain functions that are mostly unconscious (unreportable). A large body of new findings support that view. For example, brain experiments show that while unconscious visual stimuli evoke high activity in visual cortex, identical conscious stimuli reveal an additional spread of high brain activity to frontal and parietal lobes (Dehaene, 2001). Similar results have been found for hearing, touch, pain, and sensorimotor skills (Baars, 2002). The conscious waking state supports such fast, flexible, and widespread brain interactions, while unconscious states do not (Baars et al, 2004). These findings illustrate the ability of the GW framework to suggest novel and falsifiable hypotheses.

How can consciousness be addressed scientifically? The Tucson conference, founded in 1994 and celebrating its 20th anniversary in 2014, exemplifies the quest. What are the range of theories? Where do participants position themselves? Meet the founders, early visionaries, new scientists and thinkers. Progress is being made, but what does this really mean?

Russ Hurlburt — What is Consciousness?

Watch more interviews on the mystery of consciousness: https://t.ly/zGDTU
Consciousness is what we can know best and explain least. It is the inner subjective experience of what it feels like to see red or smell garlic or hear Beethoven. Consciousness has intrigued and baffled philosophers. To begin, we must define and describe consciousness. What to include in a complete definition and description of consciousness?

Understanding consciousness within the known laws of physics (Carlo Rovelli)
Posted by Dan Breeden in categories: climatology, neuroscience, quantum physics
Abstract: I do not share the feeling that consciousness (whatever this means) cannot be understood in the context of the known physical laws. So far we do not understand it well, but neither do we fully understand thunderstorms, for that matter. I offer three small contributions in the direction of a direct naturalistic account of consciousness: (i) a purely physical account of agency and the openness of the future, which traces the source of information to past low entropy; (ii) a purely physical basis for a simple notion of “meaning”; and (iii) a suggestion that current understanding of quantum matter (without need of panpsychism) weakens the apparent hiatus between the mental and the physical.
