MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html).

Definition:any structural anomaly of the anterior (ventral) part of grey matter of the substantia nigra which contains smaller and loosely packed cells than the pars compacta, only some of which contain a small amount of pigment; the cells of pars reticulata bear a strong structural and functional resemblance to the inner segment of the globus pallidus; many cells in this region use GABA as a neurotransmitter
Synonyms:exact_synonym: abnormal SNPR morphology;   abnormal pars reticularis substantiae nigrae morphology;   abnormal reticular part of substantia nigra;   abnormal substantia nigra pars reticularis morphology
