Shrinking Retrograde Amnesia [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1974 Frank Benson and I decided to publish this case not because the phenomenon was new — Ritchie Russell and Peter Nathan had described it in 1946 — but because it had been neglected. Thus many animal experimenters had attempted to study the time course of consolidation of memory traces by such experiments as teaching the animal a task and after a variable

A mathematical model of forgetting and amnesia
Frontiers in Psychology, 2013 We describe a mathematical model of learning and memory and apply it to the dynamics of forgetting and amnesia. The model is based on the hypothesis that the neural systems involved in memory at different time-scales share two fundamental properties: (1)

Temporally Graded Activation of Neocortical Regions in Response to Memories of Different Ages [PDF]
, 2007 The temporally graded memory impairment seen in many neurobehavioral disorders implies different neuroanatomical pathways and/or cognitive mechanisms involved in storage and retrieval of memories of different ages.

Socially Transmitted Food Preference (STFP) Task Protocol
Bio-Protocol, 2012 Temporally-graded retrograde amnesia (TGRA) refers to a phenomenon of premorbid memory loss whereby information acquired recently is more impaired than information acquired more remotely. Studies of human amnesia have illuminated this phenomenon (Hodges,

Suppression of neurotoxic lesion-induced seizure activity: evidence for a permanent role for the hippocampus in contextual memory. [PDF]
PLoS ONE, 2011 Damage to the hippocampus (HPC) using the excitotoxin N-methyl-D-aspartate (NMDA) can cause retrograde amnesia for contextual fear memory. This amnesia is typically attributed to loss of cells in the HPC.

Semantic Knowledge for Famous Names in Mild Cognitive Impairment [PDF]
, 2009 Person identification represents a unique category of semantic knowledge that is commonly impaired in Alzheimer\u27s disease (AD), but has received relatively little investigation in patients with mild cognitive impairment (MCI).

“I don't know why I am in hospital”: amnesia in non-fatal hanging
Heliyon, 2021 There is an extreme dearth of empirical studies assessing the neuropsychiatric outcome of non-fatal hanging that indicates little attention to the area has been paid.

Psychological factors in retrograde amnesia: self-deception and a broken heart [PDF]
, 2008 We explored potential contributing psychological factors in a patient (‘XF’) with focal retrograde amnesia, within the framework proposed by Kopelman (2000). In particular, we investigated the psychological trait of self-enhancement.

Dynamics of Hippocampal and Cortical Activation during Consolidation of a Nonspatial Memory [PDF]
, 2006 Observations of temporally graded retrograde amnesia after hippocampal damage suggest that the hippocampal region plays a critical, time-limited role in memory consolidation.

Frontiers in Neurology, 2015 Stroke is an extremely uncommon cause of transient global amnesia. Unilateral lesions of the fornix rarely cause amnesia and have not previously been reported to be associated with the distinctive amnesic picture of transient global amnesia.
