Extending Local Canonical Correlation Analysis to Handle General Linear Contrasts for fMRI Data

Figure 1

Design matrices for visual (a) and memory (b) paradigms. From left to right, the regressors are fixation (F) and visual activation (V) for the visual paradigm (a), and instruction (I), encoding (E), recognition (R), and control (C) for the memory paradigm (b). The SPM-type two-gamma function was used as the HRF. Note that with centered data, (a) can be modeled by a single centered activation column and (b) can be modeled by three centered columns. The redundant presentation was used to show all experimental conditions.
