Memories of past events can be recalled long after the event, indicating stability. But new
experiences are also integrated into existing memories, indicating plasticity. In the …

Prediction errors drive reinforcement learning and organize episodic memory into distinct
contexts, but do these effects interact? Here, we review the roles of midbrain dopamine, the …

The representation of distinct spaces by hippocampal place cells has been linked to
changes in their place fields (the locations in the environment where the place cells …

Adult-born granule cells (abGCs) have been implicated in memory discrimination through a
neural computation known as pattern separation. Here, using in vivo Ca 2+ imaging, we …

Summary Representation of the environment by hippocampal populations is known to drift
even within a familiar environment, which could reflect gradual changes in single-cell activity …

The hippocampus forms unique neural representations for distinct experiences, supporting
the formation of different memories. 1, 2, 3, 4, 5, 6 Hippocampal representations gradually …

Understanding how neuronal circuits stabilize their activity is a fundamental yet poorly
understood aspect of neuroscience. Here, we show that hippocampal network properties …

Time and experience are independent determinants of representational drift in CA1: Neuron
Skip to Main Content Advertisement Neuron This journal offers authors two options (open access …

Representational drift—the gradual continuous change of neuronal representations—has
been observed across many brain areas. It is unclear whether drift is caused by synaptic …

The dentate gyrus plays a key role in the discrimination of memories by segregating and
storing similar episodes. Whether hilar mossy cells, which constitute a major excitatory …
