Iron deficiency (ID), the most prevalent nutritional disorder in the world, impairs cognition in early development. The involvement of hippocampus in cognition has prompted investigation into distribution of the iron storage protein ferritin (FER) in rat hippocampus. (a) In normal rats, FER positive cells appeared first in lateral CA3 and hilus of dentate gyrus and then spread over the entire mossy fiber (MF) system. No such spread was observed in CA1 field. (b) Nutritional iron deficiency retarded development of FER in the MF system. No change in FER was observed in CA1 field. (c) Zinc distribution can be altered by iron deficiency. Thus, the effect of zinc added to iron supplementation was tested in iron-deficient rats. Significant FER recovery was observed only in hippocampal MF of rats receiving both zinc and iron. It is apparent that for accelerating recovery of hippocampal function in iron deficiency, both zinc and iron are required.

D009435	Synaptic Transmission	The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.

D005293	Ferritins	Iron-containing proteins that are widely distributed in animals, plants, and microorganisms. Their major function is to store IRON in a nontoxic bioavailable form. Each ferritin molecule consists of ferric iron in a hollow protein shell (APOFERRITINS) made of 24 subunits of various sequences depending on the species and tissue types.

D006624	Hippocampus	A curved elevation of GRAY MATTER extending the entire length of the floor of the TEMPORAL HORN of the LATERAL VENTRICLE (see also TEMPORAL LOBE). The hippocampus proper, subiculum, and DENTATE GYRUS constitute the hippocampal formation. Sometimes authors include the ENTORHINAL CORTEX in the hippocampal formation.
