- Feature binding as neuron synchronization: Quantum aspects F. Tito Arecchi Física, Astronomía y Matemáticas Feature binding denotes how a large collection of coupled neurons combines external signals with internalmemories into new coherent patterns of meaning. An external stimulus spreads over an assembly of coupledneurons, building up a corresponding collective state. Thus, the synchronization of spike trains of many individualneurons is the basis of a coherent perception.Homoclinic chaos has been proposed as the most suitable way to code information in time by trains of equalspikes occurring at apparently erratic times; a new quantitative indicator, called propensity, is introduced toselect the most appropriate neuron model.In order to classify the set of different perceptions, the percept space is given a metric structure. The distancein percept space is conjugate to the duration of the perception in the sense that an uncertainty relation in perceptspace is associated with time limited perceptions. Thus coding of different percepts by synchronized spike trainsentails fundamental quantum features with a quantum constant related to the details of the perceptual chain andvery different from Plancks action. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435208 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2A Vol.35
