Day 14¶
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.
The Python module search path:
import sys sys.path.append('/path/containing/modules')
Exercise — using
pearson.py
and array reshaping: Correlation per voxel, the faster way;A better regressor using convolution — Convolving with the hemodyamic response function;
Introduction to linear models — Modeling a single voxel;
Exercise — Basic linear modeling.
