Pattern separation in the hippocampus through the eyes of computational modeling

S Chavlis, P Poirazi - Synapse, 2017 - Wiley Online Library
Pattern separation is a mnemonic process that has been extensively studied over the years.
It entails the ability‐of primarily hippocampal circuits‐to distinguish between highly similar …

Different patterns of amygdala priming differentially affect dentate gyrus plasticity and corticosterone, but not CA1 plasticity

RM Vouimba, G Richter-Levin - Frontiers in neural circuits, 2013 - frontiersin.org
Stress-induced activation of the amygdala is involved in the modulation of memory

The heterogeneous population of granule cells contributes to pattern separation of the dentate gyrus neural network

K Yang, X Sun, S Zhu - Nonlinear Dynamics, 2024 - Springer
The dentate gyrus (DG) is crucial for distinguishing similar events through pattern
separation. It has been proposed that sparse firing granule cells (GCs) perform these …
