Influence of Isoflurane on Immediate-Early Gene Expression [PDF]

open access: yes, 2016
Background: Anterograde amnesia is a hallmark effect of volatile anesthetics. Isoflurane is known to affect both the translation and transcription of plasticity-associated genes required for normal memory formation in many brain regions.

Writing the Engram: Epigenetic Mechanisms of Memory Allocation

open access: yesJournal of Neurochemistry, Volume 169, Issue 12, December 2025.
Memory allocation refers to the selective recruitment of neurons to engram cells upon memory formation. While previous studies have documented the importance of intrinsic excitability and the transcription factor CREB on memory allocation, epigenetic mechanisms have remained poorly understood. Here, we summarise recent discoveries epigenetic mechanisms

Bilateral putaminal hemorrhage related to methanol poisoning: a complication of hemodialysis? Case report Hemorragia putaminal bilateral em intoxicação por metanol: uma complicação de hemodiálise? Relato de caso

open access: yesArquivos de Neuro-Psiquiatria, 1995
A case of acute methanol intoxication is presented, in which bilateral putaminal hemorrhage developed after hemodialysis. Even though the patient was initially comatose and profoundly acidotic, favorable outcome was achieved, with long-term neurologic ...

Hypoxia and retrograde amnesia [PDF]

open access: yesPsychonomic Science, 1970
Recent studies have questioned the phenomenon of hypoxia-produced RA on the premise that intracellular hypoxia cannot be produced rapidly enough to prevent the memory-consolidation process., Sixteen albino rats were trained to lever press for sucrose and were subjected to one of four treatments: shock only, hypoxia only, shock plus rapid decompression,

Rehebbilitating Memory [PDF]

open access: yes, 2015
Amnesia is a deficit of memory function that can result from trauma, stress, disease, drug use, or ageing. Though efforts are made to prevent and treat the various causes of amnesia, there remains no treatment for the symptom of memory loss itself ...

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

open access: yesAdvanced Science, Volume 12, Issue 41, November 6, 2025.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

Transient Global Amnesia with Reversible White Matter Lesions: A Variant of Posterior Reversible Encephalopathy Syndrome?

open access: yesCase Reports in Neurological Medicine, 2015
Transient global amnesia (TGA) is a self-limited disease characterized by isolated amnesia, which resolves within 24 h. In contrast, posterior reversible encephalopathy syndrome (PRES) is a potentially life-threatening disease that usually presents with ...

The Relationship of Prior Concussion and Contact Sport Exposure With Cortical Macro and Microstructure

open access: yesHuman Brain Mapping, Volume 46, Issue 16, November 2025.
A greater number of prior concussions was associated with widespread increases in cortical mean diffusivity, increased cortical surface area, and thinner anterior and medial temporal cortex in otherwise healthy collegiate athletes. Microscopic changes in gray matter associated with cumulative concussion may represent a vulnerability or antecedent to ...

Autobiographical Memory for Emotional Events in Amnesia

open access: yesBehavioural Neurology, 1996
This study investigated autobiographical memory for emotionally flavoured experiences in amnesia. Ten amnesic patients and 10 matched control subjects completed the Autobiographical Memory Interview and three semi-structured interviews which assessed ...

Evaluation of cumulative cognitive deficits from electroconvulsive therapy [PDF]

open access: yes, 2016
Background Electroconvulsive therapy (ECT) is the most effective acute treatment for severe depression, but widely held concerns about memory problems may limit its use.
