We provide a few examples of the views you can easily obtain with Brainstorm. All the 3D views can be rotated freely with the mouse, zoomed with the wheel, edited with the "Surface panel" and contextual popup menus. The MRI slices can be browsed with a simple mouse operation: right-click and mouse drag.<<BR>>[[attachment:snap_anatomy.jpg|{{attachment:snap_anatomy_sm.jpg|attachment:snap_anatomy.jpg}}]] |

MEG somatosensory evoked responses
Acquisition on an CTF 275 instrument for a left median nerve electric stimulation.
Baby auditory EEG responses
Acquisition system: EGI GSN - Baby 64 electrodes.
Continuous recordings and markers
Review recordings directly reading from the original files, edit markers, detect and correct artifacts.
Subject anatomy: MRI and surfaces
Brainstorm features the possibility to model MEG and EEG neural generators either from the individual subject anatomy, or by using a template anatomy (MNI / Colin27) that can be warped to the individual scalp surface. Multiple interactive tools are available to view, register and process the MR images and the corresponding tessellated envelopes. However, tissue segmentation must be performed using another software; multiple options exist today in the academic community (?listed here).

All the figures displayed by Brainstorm are linked in time. If they feature the same dataset, the sensor selection is also the same for all views.

Cortical regions of interest
Acquisition system: CTF MEG - 275 sensors
Scouts are cortical regions of interest, defined graphically from the "Scout" tab. They can be used to extract the time series of MEG and EEG generators within a single or mulitlple brain region.
The following example shows the cortical response to an electric stimulation of the left median nerve. With the three scouts "S1 right", "S2 right" and "S2 left", we can track the processing of the stimulus in the brain: 1) contralateral primary somatosensory cortex, 2) contralateral sencondary somatosensory, 3) ipsilateral secondary somatosensory.
Scripting environment
Everything that can be done in the interface with mouse clicks can be converted automatically to Matlab scripts, using the Process1 and Process2 tabs.
