# 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.
