The dentate gyrus (DG) has a key role in hippocampal memory formation. Intriguingly, DG
lesions impair many, but not all, hippocampus-dependent mnemonic functions, indicating …

Anatomical observations, theoretical work and lesion experiments have led to the idea that
an important function of the dentate gyrus of the mammalian hippocampus is pattern …

Memory models often emphasize the need to encode novel patterns of neural activity
imposed by sensory drive. Prior learning and innate architecture likely restrict neural …

Engrams, or the physical substrate of memory, recruit heterogeneous cell types. Targeted
reactivation of neurons processing discrete memories drives the behavioral expression of …

The theta rhythm, a quasi-periodic 4–10 Hz oscillation, is observed during memory
processing in the hippocampus, with different phases of theta hypothesized to separate …

Mammalian hippocampal circuits undergo extensive remodeling through adult
neurogenesis. While this process has been widely studied, the specific contribution of adult …

The hippocampal mossy fiber synapse, formed between axons of dentate gyrus granule
cells and dendrites of CA3 pyramidal neurons, is a key synapse in the trisynaptic circuitry of …

Key points We simulate the unitary local field potential (uLFP) generated in the
hippocampus CA3, using morphologically detailed models. The model suggests that …

Despite tremendous progress, the neural circuit dynamics underlying hippocampal
mnemonic processing remain poorly understood. We propose a new model for hippocampal …

I. Abstract The theta rhythm, a quasi-periodic 4-10 Hz oscillation, is observed during memory
processing in the hippocampus, with different phases of theta hypothesized to separate …
