Neuronale und gliale Reaktionen nach Fimbria -Fornix-Durchtrennung : zur Rolle von CNTF und LIF
… des medialen Septums (MS) nach Fimbria-Fornix-Durchtrennung. Neuere Untersuchungen lassen eine zelltyp-spezifische Wirkung der endogenen Cytokine auf GABAerge bzw. cholinerge MS-Neurone nach Axotomie vermuten. Um die Funktion von endogenem CNTF und LIF näher zu untersuchen, wurden in der …

Component diffusion tensor analysis suggests disparate temporal stem and fornix white matter pathology in Mild Cognitive Impairment
… (WM) of the limbic system, specifically the fornix, is reduced in the early stages of neurodegeneration observed in MCI. We also present data which indicate fornix integrity is linked to specific decrements in a neuropsychological measure known to be selectively sensitive to coordinated …

Neuroprotektive Funktion des Ciliary Neurotrophic Factor : Untersuchungen an CNTF-defizienten Mäusen nach Läsion der septohippokampalen Projektion
… vorliegenden Arbeit am Läsionsmodell der Fimbria-Fornix-Durchtrennung untersucht, ob dieses Zytokin als exogener neuroprotektiver Faktor wirkt. Die beobachteten Veränderungen in der Reaktion axotomierter GABAerger und cholinerger septohippokampaler Neurone lassen im Vergleich zu Wildtyptieren …

Corpus callosum morphology in children on mid-sagittal MR imaging
… to be convex, thin and have separation of the fornix insertion (all p<0.01). In young children (< 5 years) the CC was also less likely to have an identifiable isthmus (p=0.01) and was more likely to be convex (p=0.04) but the fornix was more likely to insert normally (p<0.01). Children with …

The use of misoprostol in cervical ripening and induction of labour in the term pregnancy
… (half a 200 μg tablet) in the posterior fornix or 1mg prandin gel similarly inserted. A Bishop's score of the cervix was performed prior to drug insertion and repeated by the same clinician 24 hours thereafter if labour or delivery had not ensued. If labour commenced it were managed …

Diffusion Tensor Imaging and Cognition of Transient Ischemic Attack Patients and Healthy Controls
… and radial diffusivity (RD) parameters in the fornix, a tract crucial for memory, and lower fractional anisotropy (FA) overall when compared to healthy controls. TIA patients also performed poorer on tests of executive function, episodic and working memory, and processing speed. DTI parameters …

An Electrophysiological Study of Thalamo-Hippocampal Relationships
… activating system to the septum with the dorsal fornix completing the relay to the hippocampus (Green and Arduini, 1954) and also by connections from cortical areas via the cingulum to the entorhinal area (White, 1959).

The structural neurobiology of social anxiety disorder : a clinical neuroimaging study
… Additionally reduced FA was noticed in the fornix and the right cingulum. Reduced FA was also noted in bilateral corticospinal tracts and the right corona radiata. The results demonstrate structural alterations in limbic circuitry as well as involvement of the basal glanglia and their …

Auswirkungen der Überexpression von neuronalem p21ras auf cholinerge Septumneurone der Maus : eine stereologische Studie
… und der Wildtyp-Kontrollgruppe der Fimbria-Fornix-Trakt durchtrennt und Zahl und Volumen der ChAT-positiven Neurone vier Wochen nach Läsion bestimmt. In beiden Gruppen konnte ein starker Verlust ChAT-positiver Neurone beobachtet werden. Die Anzahl und das durchschnittliche Volumen der …

Neural Mediation of Instrumental Learning and Concurrent Discrimination
… the two tasks took place in different contexts. Fornix lesions, which disconnect the hippocampal system from the anterior thalamus, impaired concurrent learning and disrupted the context-specific patterning of neuronal activity in the cingulothalamic circuit. This result is consistent with the …

Validation of magnetic resonance imaging (MRI) as a tool to detect inflammation in the brain
… were observed in regions including the fornix and sagittal stratum. Voxel-wise analysis of QMT parameters indicated an inflammatory-mediated cerebellar increase in magnetization transfer exchange rate that correlated with decreased vigour. MRSI showed an increase in temperature in a …

Neurological Effects of Low-Level, Chronic Domoic Acid Exposure in a Nonhuman Primate Model
… involved in memory processing, including the fornix and internal capsule (Petroff et al., 2019). In the second study, electroencephalography (EEG) data were collected from sedated adult females, and results suggested subtle changes in power of DA-exposed animals that may be associated with …

A metagenomic approach to understanding the relationship between the vaginal microbiome and women’s reproductive health
… were collected by swabs from the posterior fornix and cervix. We used a metagenomic approach to classify sequences to bacterial species, GroopM 102 and CheckM 104 to recover the Lactobacillus population genomes, and DIAMOND 105 to blast the predicted genes in the Lactobacillus population …
