The hippocampus has a highly ordered structure and is composed of distinct layers. Neuronal migration is an essential part of the process of the layer formation because neurons are primarily generated near the ventricle and must migrate to arrive at their final locations during brain development. Impairment of brain development is thought to underlie the etiology of psychiatric disorders. Consi...

Cognitive deficits in human infants at risk for gestationally acquired perinatal iron deficiency suggest involvement of the developing hippocampus. To understand the plausible biological explanations for hippocampal injury in perinatal iron deficiency, a neurochemical profile of 16 metabolites in the iron-deficient rat hippocampus was evaluated longitudinally by 1H NMR spectroscopy at 9.4 T. Me...

Autoradiographic localization of kainate binding sites has been determined in developing human and rat hippocampi. The results suggest differences. In particular, a transient high density of sites occurs in the supragranular layer of the fascia dentata of the human hippocampus.

We investigated the prodromal alterations of local sleep, particularly motor cortical and hippocampal along with spontaneous locomotor activity in rat models Parkinson’s disease (PD). performed our experiments adult, male Wistar rats, chronically implanted for sleep recording divided into four experimental groups: control (implanted controls), bilateral pedunculopontine tegmental nucleus (PPT) ...

This review explores the effects of fructose on hippocampus: hippocampal function and structure, neurogenesis, cognitive function. First, this result confirms that excess intake affects microstructure pathways connecting hippocampus to other brain areas. Fructose has potential affect neurogenesis in hippocampus, a diet high can impair learning memory, leading impairment. However, further resear...

Spontaneously occurring neuronal oscillations constitute a hallmark of developmental networks. They have been observed in the retina, neocortex, hippocampus, thalamus and spinal cord. In the immature hippocampus the so-called ‘giant depolarizing potentials’ (GDPs) are network-driven membrane oscillations characterized by recurrent membrane depolarization with superimposed fast action potentials...
