Dynamic Updating of Cognitive Maps via Traces of Experience in the Subiculum

Hippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT In the classical view of hippocampal function, the subiculum is assigned the role of the output layer. In spatial paradigms, some subiculum neurons manifest as so‐called boundary vector cells (BVCs), firing in response to boundaries at specific allocentric directions and distances.

Advanced Age Dissociates Dual Functions of the Perirhinal Cortex [PDF]

The Journal of Neuroscience, 2014
The perirhinal cortex (PRC) is proposed to both represent high-order sensory information and maintain those representations across delays. These cognitive processes are required for recognition memory, which declines during normal aging. Whether or not advanced age affects the ability of PRC principal cells to support these dual roles, however, is not ...

Short-term memory trace in rapidly adapting synapses of inferior temporal cortex. [PDF]

PLoS Computational Biology, 2008
Visual short-term memory tasks depend upon both the inferior temporal cortex (ITC) and the prefrontal cortex (PFC). Activity in some neurons persists after the first (sample) stimulus is shown. This delay-period activity has been proposed as an important

Microstructural Alterations in Hippocampal Subfields Mediate Age-Related Memory Decline in Humans. [PDF]

, 2020
Aging, even in the absence of clear pathology of dementia, is associated with cognitive decline. Neuroimaging, especially diffusion-weighted imaging, has been highly valuable in understanding some of these changes in live humans, non-invasively ...

Electrophysiological Signatures of Spatial Boundaries in the Human Subiculum. [PDF]

, 2018
Environmental boundaries play a crucial role in spatial navigation and memory across a wide range of distantly related species. In rodents, boundary representations have been identified at the single-cell level in the subiculum and entorhinal cortex of ...

Spatial Organization of Morpho‐Electric Subtypes of Pyramidal Neuron in the Subiculum

Hippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT The subiculum is a main output structure of the hippocampus, transmitting information from the CA1 to the entorhinal cortex in a spatially structured manner. Prior studies revealed a high electrophysiological and molecular heterogeneity of subicular pyramidal neurons (PYNs) with evidence for further spatial subdivisions of the subiculum.

Upstream CB1R Regulation of β‐Adrenergic Memory Consolidation

Hippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT Object recognition memory (ORM) plays a key role in identifying familiar items and encoding episodic information. ORM consolidation depends on β‐adrenergic receptor (βAR) signaling and is associated with increased BDNF expression in the dorsal hippocampus.

Reduced ictogenic potential of 4-aminopyridine in the perirhinal and entorhinal cortex of kainate-treated chronic epileptic rats

Neurobiology of Disease, 2008
We investigated the potential of 4-AP (50–100 μM) to induce seizure-like events (SLEs) in combined entorhinal cortex–hippocampal slices from Sprague Dawley rats which developed spontaneous limbic seizures following kainic acid induced status epilepticus.
