A model of hippocampal replay driven by experience and environmental structure facilitates spatial learning

N Diekmann, S Cheng - ELife, 2023 - elifesciences.org
Replay of neuronal sequences in the hippocampus during resting states and sleep play an
important role in learning and memory consolidation. Consistent with these functions, replay …

Distinct mechanisms and functions of episodic memory

S Cheng - Philosophical Transactions B, 2024 - royalsocietypublishing.org
The concept of episodic memory (EM) faces significant challenges by two claims: EM might
not be a distinct memory system, and EM might be an epiphenomenon of a more general …

The cost of behavioral flexibility: reversal learning driven by a spiking neural network

B Ghazinouri, S Cheng - … Conference on Simulation of Adaptive Behavior, 2024 - Springer
To survive in a changing world, animals often need to suppress an obsolete behavior and
acquire a new one. This process is known as reversal learning. The neural mechanisms …
