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.
Claims16
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.
A system for analyzing electrical activity of an organ, the system comprising:
- an input module configured to receive data corresponding to a plurality of signals based on the electrical activity;
- a first module configured to decompose the data into independent components;
- a second module configured to image a plurality of sources corresponding to the independent components;
- and
- a third module configured to generate a spatio-temporal representation of electrical activity of the organ based on the plurality of sources.
