描述了一种与人体两阶段立体定位技术在线使用的计算机程序。它有四种能力。它在大脑图谱和立体定位框架之间调换坐标，同时调整个体大脑尺寸的变化。还对电极轨迹以及头部立体定位框架放置的任何不规则进行校正。它绘制了一个操作模板，显示电极轨迹以及根据大脑矢状图适当定向收集生理数据的位置。它以伍尔西型小雕像图表的形式以图形方式显示生理数据，该图表指示以毫安为单位的阈值，并通过使用编码符号指示响应质量和某些其他数据。它将所有这些数据以及任何损伤的位置存储在磁带库中。这使得可以随时重新绘制任何个体患者的手术数据。它还允许扫描所有患者存储的方案以获取任何特定类型的数据，无论是单独的数据还是与其他数据的组合。这些检索到的信息被绘制在适当的矢状脑图上，并针对大脑大小的个体差异进行了校正。该程序的功能说明特别涉及上脑干的主要传入通路。
A computer program is described for use on-line with a two--stage stereotaxic technique in man. It has four capabilities. It transposes coordinates between a brain atlas and a stereotaxic frame, simultaneously adjusting for variations in individual brain dimensions. Corrections for electrode trajectories, and for any irregularities of placement of the stereotaxic frame in the head are also made. It plots an operative template that shows electrode trajectories and the sites from which physiological data are collected appropriately oriented upon a sagittal diagram of the brain. It graphically displays physiological data in the form of a Woolsey-type figurine chart that indicates threshold in milliamperes and, through the use of coded symbols, the quality of response and certain other data. It stores all this data in a tape library together with the locations of any lesions made. This makes it possible to replot any individual patient's operative data at any time. It also permits scanning of the stored protocols from all patients for any particular type of data either by itself or in combination with other data. This retrieved information is plotted on appropriate sagittal brain diagrams corrected for individual variations in brain size. Illustrations of the capabilities of the program are presented particularly with reference to the primary afferent pathways of the upper brain stem.
