Time-dependent reorganization of the brain components underlying memory retention in trace eyeblink conditioning. [PDF]

open access: yes, 2003
Many studies have confirmed the time-limited involvement of the hippocampus in mnemonic processes and suggested that there is reorganization of the responsible brain circuitry during memory consolidation.

Retrograde amnesia for visual memories after hippocampal damage in rats.

open access: yesLearning & memory (Cold Spring Harbor, N.Y.), 2008
It is generally believed that the hippocampus is not required for simple discrimination learning. However, a small number of studies have shown that hippocampus damage impairs retention of a previously learned visual discrimination task. We propose that,

Clinical and neuropsychological changes after the disappearance of seizures in a case of transient epileptic amnesia

open access: yesEpilepsy and Behavior Case Reports, 2017
We encountered a female patient with late-onset temporal lobe epilepsy who presented with transient amnesia as the sole ictal manifestation, an accelerated rate of forgetting daily life events, and a retrograde memory deficit.

Emotion-Induced Retrograde Amnesia Is Determined by a 5-HTT Genetic Polymorphism

open access: yesJournal of Neuroscience, 2008
A polymorphism in the human serotonin transporter (5-HTT) gene is implicated in susceptibility to anxiety and depression and in enhanced emotion-induced activation in the amygdala.

TRANSIENT GLOBAL AMNESIA IN A PATIENT WITH HYPERTENSIVE CRISIS

open access: yesАрхивъ внутренней медицины, 2018
Transient global amnesia was established by Fisher et Adams is 1964 for phenomena characterized by the sudden onset of all types memory loss, retrograde amnesia and the inability to form new  memories and to recall the recent past.

Inverse temporal contributions of the dorsal hippocampus and medial prefrontal cortex to the expression of long-term fear memories [PDF]

open access: yes, 2008
Retrograde amnesia following disruptions of hippocampal function is often temporally graded, with recent memories being more impaired. Evidence supports the existence of one or more neocortical long-term memory storage/retrieval site(s).

Could a Computer Architect Understand our Brain? [PDF]

open access: yesarXiv
This paper presents a highly speculative model encompassing the cortex, thalamus, and hippocampus of the mammalian brain. While the majority of computational neuroscience models are founded upon empirical evidence, this model is predicated upon a hardware proposal for a machine learning accelerator. Such a device was designed to perform a specific task,
