Is the cortical dynamics ergodic? A numerical study in partially symmetric networks of spiking neurons

This study shows that slow cortical dynamics emerge in partially symmetric spiking neuron networks, leading to non-ergodic behavior with long-lived activity states.

Synaptic Encoding of Time in Working Memory

This paper proposes a synaptic theory of working memory that explains how temporal information of novel sequences is encoded and retrieved through short-term synaptic plasticity over multiple time scales.

Synaptic Theory of Working Memory for Serial Order

This paper proposes a synaptic theory of working memory for serial order, suggesting that synaptic augmentation across multiple time scales encodes stimuli and their order, leading to a primacy gradient that reconstructs sequence recall.

Glassy phase in dynamically-balanced neural networks

The paper introduces a mean-field theory for balanced neuronal networks, identifying a glassy phase with non-exponential relaxation and broken ergodicity beyond a critical synaptic gain.

Discrete confidence levels revealed by sequential decisions

The paper introduces a dual-decisions method to infer confidence without explicit valuation, showing human confidence levels are discrete rather than continuous.
