This reference presents a new collection of diagrams of the human thalamus, basal ganglia, and adjoining structures for accurate targeting in stereotactic functional neurosurgery. This guide consists of a series of maps in the three stereotactic planes and comparisons between brains with similar and differing intercommissural distances to help specialists pinpoint precise targets, map through anatomic variations, and develop computerized models for stereotactic functional neurosurgery. Paired with a CD that allows for the enlargement and reader-friendly analysis of maps and illustrations found within the text, this source stands as the first atlas of the human thalamus and basal ganglia to focus on combined high stereotactic precision and anatomical resolution.
