MEG Auditory evoked potential

Acquisition system: Neuromag Vectorview306.

Description of the windows:

• Main BrainStorm window

• Timeseries of all the MEG sensors [-200ms, 500ms]
• Magnetic field recorded by the magnetometers at t=106ms
• Spatial view of the magnetometers time series [-200ms, 500ms]
• Reconstruction of the cortical currents, based on the magnetometers, at t=106ms

Multiple conditions: Baby auditory EEG

Acquisition system: EGI GSN - 64 electrodes

Description:

• One subject: "001"
• Three conditions: "GM", "GMM", "VM"
• Two views: overlaid electrodes time series, and estimated cortical sources at t=376ms

Subject anatomy: MRI and surfaces

BrainStorm offers the possibility to reconstruct the cortical activity either on the individual subject anatomy, or on a default anatomy (MNI / Colin27). For this purpose, many interactive tools are available to view, register and process the MR images and the corresponding meshes. However, the cortex segmentation must be performed by external program of your choice (?list here).

Here are a few examples of the views you can obtain with a simple click on the subject's MRI or surface. All the 3D views can be rotated freely with the mouse, zoomed with the wheel, edited with the "Surfaces panel" and with their popup menu. The MRI slices can be moved with a simple mouse operation: right-click and mouse drag.

Channel selection

All the figures displayed with BrainStorm are always linked in time; and if they represent the same datasets, the sensors selection is also the same for all the views. Selection of a channel of data is done by clicking on it, in a time series or a 3D view. Selected sensors can be displayed separately, marked as "bad", or deleted.
