1. A method of imaging brain activity comprising:
- receiving signals corresponding to electrical activity of a brain, the signals based on a plurality of scalp sensors;
decomposing the signals into spatial and temporal independent components;
localizing a plurality of sources corresponding to independent components selected based on spatial, temporal or spectral features of interest; and
generating a spatio-temporal representation of electrical activity based on the plurality of sources.

Abstract
An example includes a method of imaging brain activity. The method includes receiving signals corresponding to neuronal activity of the brain. The signals are based on a plurality of scalp sensors (110). The method also includes decomposing the signals into spatial and temporal independent components (140). In addition, the method includes localizing a plurality of sources corresponding to the independent components. The method includes generating a spatio-temporal representation of neural activity based on the plurality of sources.
