Day 15¶
Lesson plan¶
- An outline of where we’re going:
- we have tried to find “activation” by subtracting task from rest;
- we have used correlation with the on-off time-course;
- we will try a more sophisticated regressor using convolution;
- then, detection of activation by multiple regression.
- On Matrix rank;
- Testing a single voxel;
- Comparing to R with
model_one_voxel.R
; - matrix multiplying more than one column;
- Exercise — Basic linear modeling.
- Extending the model with linear and quadratic drift;
- Experimental design;
- Brain question time.
