Episodic-like memory trace in awake replay of hippocampal place cell activity sequences
eLife, 2015 Episodic memory retrieval of events at a specific place and time is effective for future planning. Sequential reactivation of the hippocampal place cells along familiar paths while the animal pauses is well suited to such a memory retrieval process.

Identifying Core Regions for Path Integration on Medial Entorhinal Cortex of Hippocampal Formation
Brain Sciences, 2020 Path integration is one of the functions that support the self-localization ability of animals. Path integration outputs position information after an animal’s movement when initial-position and movement information is input.

Multi-Scale Extension in an Entorhinal-Hippocampal Model for Cognitive Map Building
Frontiers in Neurorobotics, 2021 Neuroscience research shows that, by relying on internal spatial representations provided by the hippocampus and entorhinal cortex, mammals are able to build topological maps of environments and navigate.

Intracellular Dynamics of Virtual Place Cells [PDF]
Neural Computation, 2011 The pattern of spikes recorded from place cells in the rodent hippocampus is strongly modulated by both the spatial location in the environment and the theta rhythm. The phases of the spikes in the theta cycle advance during movement through the place field.

Bidirectional synaptic plasticity rapidly modifies hippocampal representations
eLife, 2021 Learning requires neural adaptations thought to be mediated by activity-dependent synaptic plasticity. A relatively non-standard form of synaptic plasticity driven by dendritic calcium spikes, or plateau potentials, has been reported to underlie place ...

Place Cells, Grid Cells, Attractors, and Remapping [PDF]
Neural Plasticity, 2011 Place and grid cells are thought to use a mixture of external sensory information and internal attractor dynamics to organize their activity. Attractor dynamics may explain both why neurons react coherently following sufficiently large changes to the environment (discrete attractors) and how firing patterns move smoothly from one representation to the ...

Experience-Dependent Egr1 Expression in the Hippocampus of Japanese Quail
Frontiers in Psychology, 2022 The hippocampal formation (HF) is a structure critical to navigation and many forms of memory. In mammals, the firing of place cells is widely regarded as the fundamental unit of HF information processing.

Long-term transverse imaging of the hippocampus with glass microperiscopes
eLife, 2022 The hippocampus consists of a stereotyped neuronal circuit repeated along the septal-temporal axis. This transverse circuit contains distinct subfields with stereotyped connectivity that support crucial cognitive processes, including episodic and spatial

Neuromorphic Computing and EngineeringAbstract A neuromorphic simultaneous localization and mapping (SLAM) system shows potential for more efficient implementation than its traditional counterpart. At the mean time a neuromorphic model of spatial encoding neurons in silicon could provide insights on the functionality and dynamic between each group of cells.
