“…73,81 If brain activation is strongly left lateralized, surgery in the right hemisphere is considered safe with regard to language problems, and additional invasive testing is not deemed necessary. From previous studies we calculated a cutoff value of the LI of 75 (note that these values are protocol and hardware specific).…”

“…25 More complex task designs have been developed to target such methodological pitfalls or to analyze individual hemodynamic responses to stimuli; these designs involve multiple levels of task complexity (parametric design), measurements of single stimulus-related BOLD responses (event-related design), or multiple task-control conditions (for example, conjunction analyses). 70,73 Most MR imaging units today have software for realtime automatic analysis and display results during, or immediately after, imaging. The fMR imaging maps can be implemented in neuronavigational systems for intraoperative use.…”

“…This is an important issue during presurgical language determination, which requires the exact determination of both left and right lateralized patients. Therefore, using extensive test batteries is probably advisable in a clinical setting [Ramsey et al, 2001]. On the other hand, the aim of the current study was to identify differences in the neural basis of WM processing in healthy subjects with left or right language dominance.…”

“…Однако указывается, что ва-лидность и надежность результатов можно повы-сить, используя несколько заданий, направленных на локализацию и латерализацию определенной функции. Этот подход к локализации определен-ных речевых зон назвали «комбинированным анализом» [16][17][18]. Совершены попытки увели-чения эффективности активирующих заданий для локализации зоны Брока посредством разработки новых задач [2,19], когда применяется распро-страненная в клинике задача, актуализирующая номинативную функцию языка, -называние по картинкам.…”
