Memory Gate Controlled by Contexts: Potential Key Structure That Could Link Small Associative Failures With Severe Cognitive Disorders

open access: yesBioEssays, Volume 47, Issue 8, August 2025.
Memory gate (MG) hypothesis assumes a neural structure that connects inputs to appropriate contexts. Panel A shows an input (green) that, in the MG, does not match the context (red): memory does not recognize it. Panel B shows that, in the MG, the context (green) matches the input: memory recognizes the pattern.

Neurodevelopmental Vulnerability in Alzheimer's Disease and Frontotemporal Dementia

open access: yesEuropean Journal of Neurology, Volume 32, Issue 8, August 2025.
Neurodevelopmental vulnerabilities (DV) were screened by asking about a history of a variety of neurodevelopmental disorder symptoms in participants with Alzheimer's disease (AD), frontotemporal dementia (FTD), or without cognitive impairment. K‐means clustering was performed on the factors derived from the questionnaire to identify participants with ...

Midazolam inhibits hippocampal long-term potentiation and learning through dual central and peripheral benzodiazepine receptor activation and neurosteroidogenesis [PDF]

open access: yes, 2010
Benzodiazepines (BDZs) enhance GABA(A) receptor inhibition by direct actions on central BDZ receptors (CBRs). Although some BDZs also bind mitochondrial receptors [translocator protein (18 kDa) (TSPO)] and promote the synthesis of GABA-enhancing ...
