Concept Cells and the Neural Bases of Human Memory

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Single‐neuron recordings from the medial temporal lobe of patients undergoing epilepsy surgery have revealed “concept cells” that respond selectively and invariantly to meaningful stimuli such as specific people, places, or objects. These responses offer a unique window into how individual neurons encode high‐level, multimodal representations ...

Memory consolidation from seconds to weeks: A three-stage neural network model with autonomous reinstatement dynamics

Frontiers in Computational Neuroscience, 2014
Declarative long-term memories are not created at an instant. Gradual stabilization and temporally shifting dependence of acquired declarative memories on different brain regions - called systems consolidation - can be tracked in time by lesion ...

Co‐pathologies and biological processes beyond amyloid‐beta and tau in people with Alzheimer's disease: Evidence from clinical cohort studies

Journal of Internal Medicine, Volume 299, Issue 6, Page 694-710, June 2026.
Abstract Alzheimer's disease (AD) is neuropathologically defined by amyloid‐beta (Aβ) plaques and tau neurofibrillary tangles. However, co‐pathologies and other pathobiological processes are involved in the pathogenesis of AD, contributing to neurodegeneration and clinical symptoms.

Episodic-autobiographical memory and functional amnesia

Translational Neuroscience
Memory disorders belong to the most common concomitants of brain damage, but can be found as well in cases without directly measurable brain damage. These then belong in the category of psychiatric diseases.

Transient global amnesia: an uncommon presentation of acute myocardial infarction

Italian Journal of Medicine, 2018
Transient global amnesia (TGA) is an acute neurological syndrome characterized by sudden-onset global (anterograde and retrograde) amnesia, without compromising other neurological functions. This clinical condition lasts up to 24 h with whole restoration.

Review: “The Disappointment Dilemma: Short‐ and Long‐Term Learning From Negative Outcomes”

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
The habenula routes negative‐outcome signals to VTA, RMTg, and IPN to shape aversive learning and motivation. The lateral habenula encodes acute negative prediction errors to rapidly adapt behavior to threat, fear, and avoidance. The medial habenula integrates repeated stress, drug, and aversive experiences into long‐term negative mood and expectations.

Global retrograde amnesia but selective anterograde amnesia after frontal-temporal disconnection in monkeys.

, 2008
Prefrontal cortex and inferior temporal cortex interact in support of a wide variety of learning and memory functions. In macaque monkeys, a disconnection of prefrontal and temporal cortex produces severe new learning impairments in a range of complex ...

Anterograde and Retrograde Amnesia following Bitemporal Infarction

Behavioural Neurology, 1994
A patient suffered very severe anterograde and retrograde amnesia following infarction of both medial temporal lobes (hippocampus and adjacent cortex) and the left inferior temporo-occipital area.

Hippocampus and Retrograde Amnesia in the Rat Model: A Modest Proposal for the Situation of Systems Consolidation

Neuropsychologia, 2010
The properties of retrograde amnesia after damage to the hippocampus have been explicated with some success using a rat model of human medial temporal lobe amnesia.
