Turing instabilities in biology, culture, and consciousness?

Nieuw (psychedelisch) licht op prehistorische grotschilderingen (hallucinaties): ik las er eerst over in de Knack-Avondupdate onder de pittige titel ‘Ook holbewoners zaten aan de drugs’. Toen ik op zoek ging naar de originele paper van het onderzoek, kwam ik op de blog van eerste auteur dr. Tom Froese terecht, alwaar het origineel.
“Altered states of consciousness thus provide a suitable pivot point from which to investigate the complex relationships between symbolic material culture, first-person experience, and neurobiology. We critique prominent theories of these relationships. Drawing inspiration from neurophenomenology, we sketch the beginnings of an alternative, enactive approach centered on the concepts of sense-making, value, and sensorimotor decoupling.” Deze passage in de abstract trok mijn aandacht. Dit document moet ik in mijn dagboek bewaren, dacht ik: hier en nu. |

Over first-person accounts had ik veel eerder al gelezen:
Misattribution of agency in schizophrenia: an exploration of historical first-person accounts. (J. P. M. A. Maes, A. R. van Gool, Phenomenology and the Cognitive Sciences, 2008).

One of the last pieces of work I started during my time at Ikegami Lab in Tokyo has finally been published. It is part of my efforts to try to understand the qualitative transition toward human symbolic cognition.

Turing instabilities in biology, culture, and consciousness? On the enactive origins of symbolic material culture

Tom Froese, Alexander Woodward, and Takashi Ikegami

It has been argued that the worldwide prevalence of certain types of geometric visual patterns found in prehistoric art can be best explained by the common experience of these patterns as geometric hallucinations during altered states of consciousness induced by shamanic ritual practices. And in turn the worldwide prevalence of these types of hallucinations has been explained by appealing to humanity’s shared neurobiological embodiment. Moreover, it has been proposed that neural network activity can exhibit similar types of spatiotemporal patterns, especially those caused by Turing instabilities under disinhibited, non-ordinary conditions…
