We are using the rat olfactory system to study developmental details of neurotransplantation. Tritiated [3H]thymidine-labeled fetal olfactory bulbs (OBs), were transplanted immediately into sites from which the neonatal host OB was removed. Subsequently, a small lesion was placed in the region of the transplanted OB and the tissue studied, using degeneration methods and autoradiography. Only OB's with extensive [3H]-label and precise lesions confined to the labeled areas were used. Degeneration was found mainly in the ipsilateral piriform cortex with lesser amounts at other nearby sites. The results demonstrate successfully transplanted donor OBs that send axons to specific and appropriate target areas of the host brain.

UI MeSH Term Description Entries
D009410 Nerve Degeneration Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.

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.

D009830 Olfactory Bulb Ovoid body resting on the CRIBRIFORM PLATE of the ethmoid bone where the OLFACTORY NERVE terminates. The olfactory bulb contains several types of nerve cells including the mitral cells, on whose DENDRITES the olfactory nerve synapses, forming the olfactory glomeruli. The accessory olfactory bulb, which receives the projection from the VOMERONASAL ORGAN via the vomeronasal nerve, is also included here.

D002540 Cerebral Cortex The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci.
