Abstract
A method for detecting electrical brain response in a subject includes presenting stimuli to the subject, and detecting electrical brain responses therefrom. The responses are analyzed for uncovering event related brain potentials. In one embodiment, the stimuli are presented with a predetermined inter-stimulus interval, and the subject is informed of a predetermined time range within which blinking is permitted. In another embodiment, Probe stimuli relevant to a situation under investigation are presented, and include acronyms.
Claims11
A method of detecting electrical brain response in a subject comprising:
- presenting stimuli to said subject with a predetermined inter-stimulus interval;
- informing said subject of a predetermined time range within said inter-stimulus interval during which said subject may blink;
- detecting an electrical brain response from said subject in response to each of said stimuli;
- and
- analyzing said electrical brain responses for uncovering an event related brain potential.
A method of detecting information stored in a brain of a subject comprising:
- presenting to said subject stimuli including:
- Probe stimuli relevant to a specific situation under investigation for effecting in said subject an event related brain potential when said subject has knowledge thereof, and wherein said Probe stimuli include acronyms;
- Irrelevant stimuli not relevant to said situation;
- and
- Target stimuli identified to said subject as being noteworthy, and in response to which said subject is instructed to perform a task;
- detecting an electrical brain response from said subject in response to each of said stimuli;
- analyzing said electrical brain responses for uncovering said event related brain potential therein;
- and
- comparing said electrical brain responses due to said Probe, Irrelevant, and Target stimuli for detecting said information in said subject brain based on said event related brain potential, and wherein latency of said brain responses to said stimuli is used to contribute to said detection of said information.
