Définitions de « subiculum »
Subiculum - Nom commun
-
(Anatomie) Région du cerveau localisée dans la partie inférieure de l'hippocampe.
Le subiculum, situé au cœur de l'hippocampe, joue un rôle crucial dans la consolidation de la mémoire et la navigation spatiale, révélant les complexités intimes de notre cerveau.

(Mycologie) Zone croûteuse située entre l'hyménium d'un sporophore résupiné et son support.
Dans l'univers complexe des champignons, le subiculum apparaît souvent comme une interface discrète mais cruciale, formant une zone croûteuse qui ancre l'hyménium au substrat, essentielle à la survie et à la propagation du sporophore.

(Mycologie) Étendue feutrée entourant la base de certains ascomycètes.
Le subiculum, cette étendue feutrée qui enveloppe la base des ascomycètes, témoigne de la complexité et de la finesse du monde fongique.

To investigate the flow of information from the hippocampus to the gRSC, we performed silicon probe recordings in the dorsal CA1 and subiculum and different layers of the gRSC in awake, head-fixed mice (n = 8 C57Bl/6 N). Mice were habituated for 5–7 days until they remained quiet for approximately 1 h (Methods).

The hippocampus has been hypothesized to contribute to multiple cognitive functions through parallel processing pathways within its microcircuits. Cembrowski et al. now provide further support for this model, demonstrating that the mouse hippocampal subiculum contains two discrete populations of pyramidal neurons that make distinct contributions to spatial working memory.

In summary, we report associations between CYP2C19 metabolizer status and measures of lifetime mood and global functioning, with PMs having higher scores than OMs that were mainly driven by female participants. The brain anatomy correlates of this difference were higher right hippocampal subiculum volume. We interpret our findings as behavioral and brain anatomy fingerprints of the presumed protective effect of absent CYP2C19 activity on mood in humans.
