ANALYZING EVENTS IN THE THALAMUS BY NONINVASIVE MEASUREMENTS OF THE CORTEX OF THE BRAIN

A method for obtaining information about a brain comprises the steps of providing a recording system of the electromagnetic activity produced by the brain, selecting a target pattern of the electromagnetic activity produced by the brain, recording a sample of the electromagnetic activity of the brain using the recording system, and analyzing the sample of the electromagnetic activity of the brain to identify a portion which contains the target pattern. The method further includes identifying a portion which contains the target pattern and which has a focal source at a location in the cortex of the brain, and determining the location in the thalamus which corresponds to the location of this focal source in the cortex of the brain. This determination may be followed by selecting a course of treatment which is directed to the location in the thalamus identified in the step of determining the location in the thalamus, such as a surgical, stimulative, or pharmaceutical treatment.
