Tutorials
Important notes
- In all the tutorials, we will consider that you are working with the source distribution of Brainstorm, as it is the recommanded way to use this toolbox.
- If you are working with compiled binaries, some menus might be missing, but everything else should work the same way.
Before starting using Brainstorm with your own data, you should go through all the tutorials in "Getting started with Brainstorm" section.
In just a few hours, they will introduce you to most of the main features of the application.
- If you want a printed version of this documentation:
- Open a tutorial, go to the menu on top of the page,

Getting started with Brainstorm
Dataset description
You should already have downloaded this package if you have done correctly the previous tutorial. If it is not the case, go back to the ?previous tutorial and follow all the instructions to create the TutorialCTF protocol.

Acquisition system: |
CTF MEG, 151 axial gradiometers, La Salpetriere Hospital, Paris |
Protocol: |
Shuffled electrical stimulations of the thumb fingers from both hands. The idea is to get a map of the primary sensory response on the cortex |

- Cortex and head surfaces extracted with BrainVISA software ||

- somMDYO-18av.ds: average response for the stimulation of the left thumb (one subject, 400 trials) ||
Observations: |
Stimulus occurs at time 0. There's a first tiny wave occuring at about 20ms or so but it's not too clear on all fingers. So if you are to compute cortical maps, start by the 40ms peak which is also of interest and which has much better SNR. |
