Dreaming with hippocampal damage

eLife, 2020
The hippocampus is linked with both sleep and memory, but there is debate about whether a salient aspect of sleep – dreaming – requires its input. To address this question, we investigated if human patients with focal bilateral hippocampal damage and ...

Profound anterograde amnesia following routine anaesthetic and dental procedure: a new classification of amnesia characterised by intermediate-to-late stage consolidation failure?

, 2015
Anterograde amnesia caused by bilateral hippocampal or diencephalon damage manifests in characteristic symptoms of preserved intellect and implicit learning, and short span of awareness with complete and rapid forgetting of episodic material.

Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose

Drug Testing and Analysis, EarlyView.
A single oral dose of diphenhydramine and cyclizine can be quantified in human head hair for a minimum of 5 months and, in certain cases, for up to 1 year following intake. Among 12 study participants, the measured concentrations ranged from 0 to 610 pg/mg within 1 year post‐intake.

Cross-Situational Statistical Learning of New Words Despite Bilateral Hippocampal Damage and Severe Amnesia

Frontiers in Human Neuroscience, 2020
Word learning requires learners to bind together arbitrarily-related phonological, visual, and conceptual information. Prior work suggests that this binding can be robustly achieved via incidental cross-situational statistical exposure to words and ...

Acute-onset amnesia: transient global amnesia and other causes [PDF]

, 2022
Acute-onset amnesia is a dramatic neurological presentation that can cause considerable concern to both patient and clinician. The patient typically presents with an inability to not only retain new memories but also access previously acquired ...

Phase I Metabolism of Novel Phencyclidine Derivative 3‐Cl‐PCP: In Vitro Studies With Pooled Human Liver Microsomes and Investigation of a Post‐Mortem Case

Drug Testing and Analysis, EarlyView.
A fatal 3‐chloro‐phencyclidine (3‐Cl‐PCP) intoxication was investigated by analyzing postmortem samples and a pooled human liver microsomes assay. Tentative metabolite identification was performed by liquid chromatography‐quadrupole time‐of‐flight mass spectrometry (LC‐QTOF‐MS). Seven phase I metabolites were identified.

Network-wide abnormalities explain memory variability in hippocampal amnesia [PDF]

, 2019
Patients with hippocampal amnesia play a central role in memory neuroscience but the neural underpinnings of amnesia are hotly debated. We hypothesized that focal hippocampal damage is associated with changes across the extended hippocampal system and ...

Graded extent of hippocampal resection is related to neuropsychological outcomes in temporal lobe epilepsy surgery

Epilepsia, EarlyView.
Abstract Objective Surgical resection for epilepsy seeks to maximize seizure freedom while minimizing new neurocognitive impairments. Tailored resections guided by anatomoelectroclinical (AEC) hypotheses offer the possibility of sparing parts of the hippocampus.

Isolated Mammillary Bodies Damage—An Atypical Presentation of Wernicke Syndrome

Behavioral Sciences, 2018
We report atypical magnetic resonance imaging (MRI) lesions in a case of Wernicke encephalopathy. The patient presented with isolated anterograde amnesia following a partial colectomy complicated by peritonitis. Fluid-attenuated inversion recovery and T2

Psychogenic amnesia

NeuroImage, 2003
Time- and content-based memory systems are briefly described so that their importance for a refined analysis of memory disturbances becomes evident. These memory systems are then related to their brain instantiation, emphasizing that there are limbic circuits for encoding different forms of memories, largely cortical networks for memory storage, and a ...
