P.2013-10-15T15:39:16Z2013-10-15T15:39:16Z20061550-2376http://www.repositorio.ufba.br/ri/handle/ri/13254v.74 n. 4p.041912-1-041912-12We consider a coupled map lattice defined on a hypercube in M dimensions, taken here as the information space, to model memory retrieval and information association by a neural network. We assume that both neuronal activity and spike timing may carry information. In this model the state of the network at a given time t is completely determined by the intensity y , t with which the information pattern represented by the integer is being expressed by the network. Logistic maps, coupled in the information space, are used to describe the evolution of the intensity function y , t with the intent to model memory retrieval in neural systems. We calculate the phase diagram of the system regarding the model ability to work as an associative memory. We show that this model is capable of retrieving simultaneously a correlated set of memories, after a relatively long transient that may be associated to the retrieving of concatenated memorized patterns that lead to a final attractor.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2013-07-04T14:29:30Z No. of bitstreams: 1 e041912.pdf: 605454 bytes, checksum: b55964aec26404fd995223fdfaab33ef (MD5)Rejected by Alda Lima da Silva(sivalda@ufba.br), reason: Material de Física on 2013-08-16T19:18:55Z (GMT)Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2013-08-27T11:14:52Z No. of bitstreams: 1 e041912.pdf: 605454 bytes, checksum: b55964aec26404fd995223fdfaab33ef (MD5)Approved for entry into archive by Rodrigo Meirelles(rodrigomei@ufba.br) on 2013-10-15T15:39:16Z (GMT) No. of bitstreams: 1 e041912.pdf: 605454 bytes, checksum: b55964aec26404fd995223fdfaab33ef (MD5)Made available in DSpace on 2013-10-15T15:39:16Z (GMT).
