Remembering the "When": Hebbian Memory Models for the Time of Past Events

The paper develops Hebbian memory models to simulate how neural mechanisms enable remembering the time of past events, showing multiple biologically plausible implementations.

Representational similarity modulates neural and behavioral signatures of novelty

This study presents a model explaining how stimulus representations affect novelty signals in the brain and behavior, using mouse data to show effects on visual cortex responses and exploration.

Even if suboptimal, novelty drives human exploration

This study shows humans persistently explore stochastic environments despite suboptimal strategies, driven by novelty rather than optimal information gain.

Learning is a fundamental source of behavioral individuality

The paper shows that learning increases behavioral individuality in genetically identical flies, distinguishing it from genetic and environmental factors.

Surprise: a unified theory and experimental predictions

The paper identifies 16 mathematical definitions of surprise, classifies them into four categories, and proposes a combined definition with experimental predictions.

Novelty is not Surprise: Human exploratory and adaptive behavior in sequential decision-making

This study introduces a deep sequential decision-making paradigm to explain human behavior by incorporating novelty and surprise, showing that model-free actions dominate decisions despite the availability of a world-model.

Rapid suppression and sustained activation of distinct cortical regions for a delayed sensory-triggered motor response

This study identifies cortical regions involved in delayed sensory-triggered motor responses in mice using calcium imaging and electrophysiology.
