Grazia Pulvirenti, Renata Gambino, The paradox of Romantic ekphrasis. Metacritic discourse, perception and imagination in art descripti

Ekphrasis is a text genre based on the intertwining of visual and verbal features, involving the processes of both reading, and priming a visual image or a related action. We argue in this study that...

The nature of consciousness, its occurrence in the brain, and its ultimate place in the universe are unknown. We proposed in the mid 1990's that consciousness depends on biologically 'orchestrated' quantum computations in collections of microtubules within brain neurons, that these quantum computations correlate with and regulate neuronal activity, and that the continuous Schrödinger evolution of each quantum computation terminates in accordance with the specific Diósi–Penrose (DP) scheme of 'objective reduction' of the quantum state (OR). This orchestrated OR activity (Orch OR) is taken to result in a moment of conscious awareness and/or choice. This particular (DP) form of OR is taken to be a quantum-gravity process related to the fundamentals of spacetime geometry, so Orch OR suggests a connection between brain biomolecular processes and fine-scale structure of the universe. Here we review and update Orch OR in light of criticisms and developments in quantum biology, neuroscience, physics and cosmology. We conclude that consciousness plays an intrinsic role in the universe. KEY WORDS: Consciousness, microtubules, OR, Orch OR, quantum computation, quantum gravity
