Interactive Brain Activation for fMRI Data vs Imaging Stress Task

The app provides an interactive approach to visualize which areas of the brain are active in a subject that is performing a motor task. The differences between two p-value data sets are shown, one data set shows activated areas according to a traditional approach ("Independent"), and one with a new method proposed by scientists at KAUST and Newcastle University ("Space Time Model"). Green represent areas where the proposed Space Time Model produces lower p-values. Red represents areas where the traditional method produces lower p-values. White suggests the two model produce similar p-values.

Easily test the impact of time pressure and performance-related stress using adaptive math questions. The task consists of a practice phase, followed by a control phase and an experimental stress phase. After completion, results are displayed as binary values (1 = correct response, 0 = incorrect response), allowing for straightforward export and analysis in Excel or other statistical software. This app is inspired by the Montreal Imaging Stress Task (MIST) protocol as described in: Dedovic, K., Renwick, R., Mahani, N. K., Engert, V., Lupien, S. J., & Pruessner, J. C. (2005).
