Abstract:
:Investigations in toxicologic neuropathology are complex undertakings because of the intricate spatial and temporal diversity in the anatomic, functional, and molecular organization of the central and peripheral nervous systems. This compilation of toxicologic neuropathology resources has been designed to consolidate a broad range of useful neurobiology, neuropathology, and neurotoxicology resources in a single reference. This collection will increase familiarity with the basic knowledge, skills, and tools required for the proficient practice of toxicologic neuropathology and should help to improve the analysis and interpretation of pathology data sets from neural tissues in toxicology studies.
