Description

DESCRIPTION (provided by applicant): Knowledge of cerebral cortical connectivity in primates is essential for understanding higher brain mechanisms of sensation, perception and cognition and their disorders but connection tracing studies are increasingly uncommon, older studies are accessible only through publications which represent an earlier investigator's interpretation of the data, and access to the original data for re-interpretation is commonly unavailable. Retrieval of archives of experimental material and conversion to an accessible digital form presents considerable logistical and other handicaps. We seek to develop a comprehensive and ongoing archive of material demonstrating cortical and subcortical connectivity in rhesus monkey brains, in which all the histological material from individual experiments is available in its digital form, with a suitable search engine providing open access to all investigators. In this way, original experimental data can be annotated and re-interpreted as newer parcellations of cortical and subcortical structures are made on the basis of accumulating functional and clinical data. The current proposal builds on expertise in constructing high resolution microscopic atlases of primate brain architecture and will create a searchable database of connections of the cerebral cortex in the adult rhesus monkey. A pipeline will be established in which targeted cortical areas in a series of monkeys will be injected with a tracer transported both retrogradely and anterogradely. Digital data about each individual brain will be collected by means of: structural mri; serial imaging of the sectioned blockface as each 40
