Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose

open access: yesDrug Testing and Analysis, Volume 18, Issue 7, Page 877-892, July 2026.
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.

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,

Transcranial Direct Current Stimulation (tDCS) for the Treatment of Hemolacria Comorbid With Psychiatric and Somatic Symptoms: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Hemolacria is a rare condition characterized by bloody tears. Its etiology is often multifactorial, but functional/psychosomatic mechanisms have been proposed when organic causes are excluded. A 48‐year‐old woman with a history of multiple traumatic brain injuries (coma in 2008, car accident in 2017) presented with refractory generalized ...

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

open access: yesFrontiers 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 ...

Concept Cells and the Neural Bases of Human Memory

open access: yesActa 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 ...

Episodic-autobiographical memory and functional amnesia

open access: yesTranslational 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

open access: yesItalian 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.
