Pattern Separation in a Spiking Neural Network of Hippocampus Robust to Imbalanced Excitation/Inhibition [PDF]
arXiv, 2018 Efficient pattern separation in dentate gyrus plays an important role in storing information in the hippocampus. Current knowledge of the structure and function of the hippocampus, entorhinal cortex and dentate gyrus, in pattern separation are incorporated in our model. A three-layer feedforward spiking neural network inspired by the rodent hippocampus

Hippocampus: Remembering the Choices [PDF]
Neuron, 2013 The hippocampus is said to be involved in "navigation" and "memory" as if these were distinct functions. In this issue of Neuron, Singer et al. (2013) provide evidence that the hippocampus retrieves spatial sequences in support of memory, strengthening a convergence between the two perspectives on hippocampal function.
