The neuropathology of the brain of mutant spastic Han-Wistar rats (Han-Wist SPA/SPA) was investigated using histological techniques. A surprising result was the detection of neuronal degeneration in the hippocampus and cerebellum of mutant spastic rat brains, whereas other regions, e.g. neocortex, isocortex, basal ganglia and thalamus, were overall normal. The CA3 sector in the septal third of the hippocampus including the cell band reaching into the hilus ('CA3c') showed a severe neuronal degeneration, whereas the granule cells of the dentate gyrus, several hilar neurons ('CA4') and the pyramidal cells in CA1 were found normal. In the cerebellum, a variable patchy degeneration of Purkinje cells was detected while the general layering was normal and granule cells and Golgi cells appeared preserved.

D009135 Muscular Diseases Acquired, familial, and congenital disorders of SKELETAL MUSCLE and SMOOTH MUSCLE. Muscle Disorders,Myopathies,Myopathic Conditions,Muscle Disorder,Muscular Disease,Myopathic Condition,Myopathy
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
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.

D011712 Pyramidal Tracts Fibers that arise from cells within the cerebral cortex, pass through the medullary pyramid, and descend in the spinal cord.

D011919 Rats, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions.

D002531 Cerebellum The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills. Cerebella,Corpus Cerebelli,Parencephalon,Cerebellums,Parencephalons
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.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
