1. Ressecação de lesões em area motora cortical e subcortical e avaliação quanto ao uso dos metodos auxiliares intraoperatorios / Resection of lesions in the cortical and subcortical motor area and evolution of the intraoperative auxiliary methods
Nos últimos anos, consideráveis avanços tecnológicos, principalmente métodos de localização funcional do córtex cerebral, têm surgido no sentido de melhorar os resultados cirúrgicos no tratamento de lesões em áreas eloqüentes. O objetivo deste estudo é avaliar os resultados pós-operatórios em 74 pacientes submetidos à ressecção de lesões

2. Accuracy of stereotaxic localisation using MRI and CT.
The accuracy of stereotaxic coordinates determined using the Leksell apparatus with CT and MRI was investigated using an Agar filled head phantom. Both imaging techniques were found to produce an accuracy of better than 2 mm with the exception of the Z coordinate as measured by CT (2.3 mm). This latter error is greater because of the 3 mm slice width used. D

3. A graphical anatomical database of neural connectivity.
We describe a graphical anatomical database program, called XANAT (so named because it was developed under the X window system in UNIX), that allows the results of numerous studies on neuroanatomical connections to be stored, compared and analysed in a standardized format. Data are entered into the database by drawing injection and label sites from a particu
