Lateral Thinking: Exploring the Lateral Entorhinal Cortex Projections to the Hippocampus in the Rodent Brain

Journal of Comparative Neurology, Volume 533, Issue 7, July 2025.
Localization and layers of the lateral entorhinal cortex. Photomicrographs depicting both coronal (A: 1–4) and sagittal (B: 5–8) sections from a mouse brain to show different perspectives of the entorhinal cortex inputs to the hippocampus (HC). Sections were stained with toluidine blue to aid with the visualization of the six layers of the lateral ...

Septotemporal Variation in Theta Rhythm Dynamics: Effects of Speed and Habituation

, 2011
Theta (6-12 Hz) field potentials and the synchronization (coherence) of these potentials present neural network indices of hippocampal physiology. Theta signals within the hippocampal formation may reflect alterations in sensorimotor integration, the ...

Giant depolarizing potentials: the septal pole of the hippocampus paces the activity of the developing intact septohippocampal complex in vitro. [PDF]

, 1998
International audienceIn neonatal hippocampal slices, recurrent spontaneous giant depolarizing potentials (GDPs) provide neuronal synchronized firing and Ca2+ oscillations.

Maturation of hippocampus-medial prefrontal cortex projections defines a pathway-specific sensitive period for cognitive flexibility

Cell Reports
Summary: The septotemporal axis of the hippocampus separates it into domains with unique molecular, cellular, downstream connectivity, and behavioral profiles, and yet very little is known about the ontogenesis of these highly specialized subcircuits ...

Pursuing Synaptic Plasticity From Cortex to LTP in the Hippocampus

Hippocampus, Volume 35, Issue 1, January 2025.
ABSTRACT Here I describe how an interest in synaptic plasticity took me from a PhD at McGill, where I worked on activity‐dependent plasticity in the responses of single units in the association cortex of anesthetized cats, to a collaboration with Terje Lømo in Per Andersen's laboratory in Oslo in 1968–9. There we followed up on Lømo's discovery of LTP,

Dynamics of spike transmission and suppression between principal cells and interneurons in the hippocampus and entorhinal cortex

Hippocampus, Volume 34, Issue 8, Page 393-421, August 2024.
Abstract Synaptic excitation and inhibition are essential for neuronal communication. However, the variables that regulate synaptic excitation and inhibition in the intact brain remain largely unknown. Here, we examined how spike transmission and suppression between principal cells (PCs) and interneurons (INTs) are modulated by activity history, brain ...

α7 nicotinic acetylcholine receptors induce long‐term synaptic enhancement in the dorsal but not ventral hippocampus

Synapse, Volume 78, Issue 1, January 2024.
This study shows that activation of α7nAChRs induces long‐lasting enhancement of excitatory synaptic transmission in the dorsal but not the ventral CA3‐CA1 synapses despite a similar receptor expression in the two segments of the hippocampus. Abstract Agents that positively modulate the activity of α7nAChRs are used as cognitive enhancers and for the ...

NECAB1-3, parvalbumin, calbindin, and calretinin in the hippocampus of the European mole

Frontiers in Neuroanatomy
Many calcium-binding proteins are expressed in a region-and cell-type specific manner in the mammalian hippocampus. Neuronal calcium-binding proteins (NECABs) are also expressed in hippocampal neurons, but few species have been investigated, with partly ...

Differential functions of the dorsal and intermediate regions of the hippocampus for optimal goal-directed navigation in VR space

eLife
Goal-directed navigation requires the hippocampus to process spatial information in a value-dependent manner, but its underlying mechanism needs to be better understood. Here, we investigated whether the dorsal (dHP) and intermediate (iHP) regions of the

Comparative Anatomy of the Dentate Mossy Cells in Nonhuman Primates: Their Spatial Distributions and Axonal Projections Compared With Mouse Mossy Cells [PDF]

Glutamatergic mossy cells (MCs) mediate associational and commissural connectivity, exhibiting significant heterogeneity along the septotemporal axis of the mouse dentate gyrus (DG).
