Injections of WGA-HRP were placed into different regions of the hippocampal formation and sections through the septal complex were processed for the simultaneous demonstration of the.
RAT SEPTUM HIPPOCAMPUS ANATOMY PDF
The present study of corticosterone treatment in young rats demonstrates interactions of steroid hormones with neurotrophic factors and their receptors in the septo-hippocampal system during the first two postnatal weeks. Request PDF Genomic Anatomy of the Hippocampus Availability of genome-scale in situ hybridization data allows systematic analysis of genetic neuroanatomical architecture. These experiments were directed at determining the proportion and distribution of cholinergic septal cells which project to the rat hippocampal formation. Quantification of the neurotrophin protein levels using an ELISA revealed significant treatment effects for NGF and NT-4/5 in the hippocampus. Particularly, the gene expression of NGF, NT-3, and the high affinity receptors trkA, trkB and trkC increased significantly. The subcallosal gyrus is a relatively small gyrus that is found anterior to the lamina terminalis (anterior wall of the hypothalamus) and the anterior commissure.Also, it is inferior to the rostrum (first part) of the corpus callosum and posterosuperior to the orbitofrontal cortex of the cerebrum. In the septal region, we found an unchanged mRNA expression after corticosterone treatment, whereas in the hippocampus there was a general increase in mRNA. The MS and the HIPP have reciprocal connections and it is not. The MS theta pacemaker hypothesis has solid foundation but the MS-hippocampal interactions during different behavioral states are poorly understood. The mRNA and protein levels of the neurotrophins of the NGF family (NGF, BDNF, NT-3 and NT-4/5) and their receptors (trkA, trkB, trkC and p75) were quantified in septum and hippocampus using RT-PCR. The medial septum (MS) plays an essential role in rhythmogenesis in the hippocampus (HIPP) theta-rhythmic bursts of MS neurons are believed to drive theta oscillations in rats’ HIPP.

Swanson CA1 field of the hippocampus in human, monkey and rat Insausti and Amaral CA3/. The topographical organization of the hippocampal projection to the septal area: a comparative neuroanatomical analysis in the gerbil, rat, rabbit, and cat, J. Newborn rats were treated with corticosterone-containing polymers until postnatal day 12. HIPPOCAMPUS and SEPTUM From Hendelman, 2000 1-rhinal sulcus 2. In the present study we investigated the effects of early postnatal corticosterone treatment in rats on neurotrophic factors of the nerve growth factor (NGF) family and their receptors. Putative corticosterone-triggered mediators are neurotrophins. The principal glucocorticoid in rats, corticosterone, interacts with neurons in the limbic system and leads to morphological and behavioral changes.
