Hippocampus, 1992
AbstractPrevious studies have demonstrated regional variation in the anatomical organization and physiological properties of the hippocampus along its septotemporal (dorsoventral) axis. In this study, regional variation of the supragranular projection of the mossy fiber pathway in the dentate gyrus of normal and kindled rats was characterized with a ...

Effects of neuregulin-1 administration on neurogenesis in the adult mouse hippocampus and characterization of immature neurons along the septotemporal axis [PDF]
Scientific Reports, 2016 AbstractAdult hippocampal neurogenesis is associated with learning and affective behavioural regulation. Its diverse functionality is segregated along the septotemporal axis from the dorsal to ventral hippocampus. However, features distinguishing immature neurons in these regions have yet to be characterized.

The functional organization of the hippocampus along its longitudinal (septotemporal or dorsoventral) axis is conspicuously heterogeneous. This functional diversification includes the activity of sharp wave and ripples (SPW-Rs), a complex intrinsic network pattern involved in memory consolidation. In this study, using transverse slices from the ventral

AbstractThe projection of the entorhinal cortex (EA) to the hippocampus in the cat has been studied by electrophysiological methods. Field potentials elicited by EA stimulation sites were measured in the hippocampus (fascia dentata). Different topographic distributions of the amplitude and of the onset latency of average evoked potentials (AEPs) were ...

Neuroscience and Behavioral Physiology, 2021
Functional differentiation of the hippocampus along its longitudinal septotemporal axis is beyond doubt, though the factors determining this subregional specificity remain controversial. The spatial specificity gradient of hippocampal place cells decreases along its longitudinal axis from the septal pole to the temporal area.

The distribution of glutamate receptors in transverse hippocampal sections has been well investigated. However, in spite of the known septotemporal gradients of hippocampal connectivity no systematic studies exist about the distribution of glutamate receptors along the septotemporal (longitudinal) hippocampal axis.

Theta and gamma coherence across the septotemporal axis during distinct behavioral states
Hippocampus, 2011AbstractTheta (4–12 Hz) and gamma (40–100 Hz) field potentials represent the interaction of synchronized synaptic input onto distinct neuronal populations within the hippocampal formation. Theta is quite prominent during exploratory activity, locomotion, and REM sleep.

Fluoxetine induces input-specific hippocampal dendritic spine remodeling along the septotemporal axis in adulthood and middle age [PDF]
Hippocampus, 2015 ABSTRACTFluoxetine, a selective serotonin‐reuptake inhibitor (SSRI), is known to induce structural rearrangements and changes in synaptic transmission in hippocampal circuitry. In the adult hippocampus, structural changes include neurogenesis, dendritic, and axonal plasticity of pyramidal and dentate granule neurons, and dedifferentiation of dentate ...

AbstractRetrograde tracing experiments were performed to clarify the topographic projection from medial (area 28m) and intermediate (area 28i) divisions of the entorhinal cortex to the dentate gyrus. Pipets filled with horseradish peroxidase (HRP) were positioned by electrophysiologic guidance at one of several septotemporal (S‐T) levels in the dentate

Septotemporal gradients of trimethyltin-induced hippocampal lesions.
Neurobehavioral toxicology and teratology, 1985Rats were administered 6 mg/kg trimethyltin (TMT) PO, and sacrificed at various time points (up to 60 days) for pathological evaluation. Studies along the full extent of the septotemporal axis revealed region-specific and cell field-specific damage. Dentate granule cells were most affected at the temporal pole and were only minimally affected at the ...
