Cross-attractor repertoire provides new perspective on structure-function relationship in the brain
NeuroImage, 2022 The brain exhibits complex intrinsic dynamics, i.e., spontaneously arising activity patterns without any external inputs or tasks. Such intrinsic dynamics and their alteration are thought to play crucial roles in typical as well as atypical cognitive ...

Reinforcing Neural Network Stability with Attractor Dynamics
, 2020 Recent approaches interpret deep neural works (DNNs) as dynamical systems, drawing the connection between stability in forward propagation and generalization of DNNs.

Detecting changes in forced climate attractors with Wasserstein distance [PDF]
Nonlinear Processes in Geophysics, 2017 The climate system can been described by a dynamical system and its associated attractor. The dynamics of this attractor depends on the external forcings that influence the climate.

Memory Dynamics in Attractor Networks [PDF]
Computational Intelligence and Neuroscience, 2015 As can be represented by neurons and their synaptic connections, attractor networks are widely believed to underlie biological memory systems and have been used extensively in recent years to model the storage and retrieval process of memory. In this paper, we propose a new energy function, which is nonnegative and attains zero values only at the ...

Hidden Attractors in Discrete Dynamical Systems [PDF]
Entropy, 2021 Research using chaos theory allows for a better understanding of many phenomena modeled by means of dynamical systems. The appearance of chaos in a given process can lead to very negative effects, e.g., in the construction of bridges or in systems based on chemical reactors.

Corvids optimize working memory by categorizing continuous stimuli
Communications Biology, 2023 Working memory (WM) is a crucial element of the higher cognition of primates and corvid songbirds. Despite its importance, WM has a severely limited capacity and is vulnerable to noise.

Continuous attractors for dynamic memories
eLife, 2020 Episodic memory has a dynamic nature: when we recall past episodes, we retrieve not only their content, but also their temporal structure. The phenomenon of replay, in the hippocampus of mammals, offers a remarkable example of this temporal dynamics.

Attractor–repeller collision and the heterodimensional dynamics
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2023 We study the heterodimensional dynamics in a simple map on a three-dimensional torus. This map consists of a two-dimensional driving Anosov map and a one-dimensional driven Möbius map, and demonstrates the collision of a chaotic attractor with a chaotic repeller if parameters are varied.

Hidden Strange Nonchaotic Attractors
Mathematics, 2021 In this paper, it is found numerically that the previously found hidden chaotic attractors of the Rabinovich–Fabrikant system actually present the characteristics of strange nonchaotic attractors.
