Slow and Fast Neurons Cooperate in Contextual Working Memory through Timescale Diversity
Tomoki Kurikawa
Neural systems process information across a broad range of intrinsic timescales, both within and across cortical areas. While such diversity is a hallmark of biological networks, i…
Stability Control of Metastable States as a Unified Mechanism for Flexible Temporal Modulation in Cognitive Processing
Tomoki Kurikawa, Kunihiko Kaneko
Flexible modulation of temporal dynamics in neural sequences underlies many cognitive processes. For instance, we can adaptively change the speed of motor sequences and speech. Whi…
Fluctuation-learning relationship in neural networks
Tomoki Kurikawa, Kunihiko Kaneko
Learning in neural systems occurs through change in synaptic connectivity that is driven by neural activity. Learning performance is influenced by both neural activity and the task…
Solvable Neural Network Model for Input-Output Associations: Optimal Recall at the Onset of Chaos
Tomoki Kurikawa, Kunihiko Kaneko
In neural information processing, an input modulates neural dynamics to generate a desired output. To unravel the dynamics and underlying neural connectivity enabling such input-ou…
Transitions among metastable states underlie context-dependent working memories in a multiple timescale network
Tomoki Kurikawa
Transitions between metastable states are commonly observed in the neural system and underlie various cognitive functions such as working memory. In a previous study, we have devel…
Multiple-timescale Neural Networks: Generation of Context-dependent Sequences and Inference through Autonomous Bifurcations
Tomoki Kurikawa, Kunihiko Kaneko
Sequential transitions between metastable states are ubiquitously observed in the neural system and underlie various cognitive functions. Although a number of studies with asymmetr…
Repeated sequential learning increases memory capacity via effective decorrelation in a recurrent neural network
Tomoki Kurikawa, Omri Barak, Kunihiko Kaneko
Memories in neural system are shaped through the interplay of neural and learning dynamics under external inputs. By introducing a simple local learning rule to a neural network, w…
