Abstract

Methods and systems are disclosed for a guidance application that allows a practitioner to easily correlate a fluctuation in any channel of a plurality of channels constituting received electroencephalography (“EEG”) data to a particular physical manifestation. For example, the guidance application automatically synchronizes incoming EEG data to the physical manifestations and allows for automatic retrieval a portion of video data (e.g., of the physical manifestation) that corresponds to a selected portion of EEG data.

Claims

1. A method of correlating brain activity to physical manifestations, the method comprising:

receiving data indicative of at least one of a hyperventilation period or a post-hyperventilation period;

receiving electroencephalography (“

EEG”

) data comprising a plurality of EEG channels, wherein each EEG channel of the plurality of EEG channels comprises a plurality of EEG instances;

receiving video data of a subject from which the received EEG data is based;

correlating each EEG instance of the plurality of EEG instances to a respective portion of the video data in a database;

receiving a first user input selecting a first EEG instance of the plurality of EEG instances;

in response to receiving the first user input, cross-referencing the first EEG instance with the database to determine a first portion of the video data that corresponds to the first EEG instance;

correlating the data indicative of the at least one of the hyperventilation period or the post-hyperventilation period with at least one of the plurality of EEG instances or the first portion of the video data; and

generating for concurrent display, on a display device, the first portion of the video data, the plurality of EEG instances, and a graphic, separate from the plurality of EEG instances, that visually indicates a progression of the at least one of the hyperventilation period or the post-hyperventilation period correlated with the at least one of the plurality of EEG instances or the first portion of the video data.

2. The method of claim 1, further comprising:

generating for display, on the display screen, a graphical representation of each EEG channel; and

overlaying the first portion on the graphical representation of each EEG channel.

3. The method of claim 2, further comprising:

generating for display the graphical representation of each EEG channel in a region of the display screen; and

determining a plurality of sub-regions within the region, wherein a first sub-region of the plurality of sub-regions corresponds to the first portion.

4. The method of claim 3, further comprising:

determining that the first EEG instance corresponds to the first sub-region;

determining that a second EEG instance corresponds to the first sub-region; and

generating for display the first portion in response to a user input selecting either the first EEG instance or the second EEG instance.

5. The method of claim 4, wherein the first EEG instance corresponds to a first EEG channel of the plurality of EEG channels and the second EEG instance corresponds to a second EEG channel of the plurality of EEG channels.

6. The method of claim 5, wherein the first user input selecting the first EEG instance of the plurality of EEG instances comprises hovering an on-screen icon in the first sub-region.

7. The method of claim 1, further comprising:

while the first portion is generated for display, receiving a second user input selecting a second EEG instance of the plurality of EEG instances;

in response to receiving the second user input, cross-referencing the second EEG instance with the database to determine a second portion of the video data that corresponds to the first EEG instance; and

replacing, on the display device, the first portion with the second portion.

8. The method of claim 1, further comprising:

generating a time stamp for the first instance that corresponds to a location in the received EEG data;

generating a time stamp for the first portion that corresponds to a location of the first portion in the video data; and

determining that the time stamp for the first instance corresponds to the time stamp for the first portion.

9. The method of claim 8, wherein the location in the received EEG data corresponds to a first sub-region of a plurality of sub-regions in a region of the display screen corresponding to a graphical representation of each EEG channel.

10. The method of claim 9, wherein the first sub-region corresponds to the first instance that corresponds to a first EEG channel of the plurality of EEG channels and a second EEG instance that corresponds to a second EEG channel of the plurality of EEG channels.

11. A system for correlating brain activity to physical manifestations, the system comprising:

a database; and

control circuitry configured to;

receive data indicative of at least one of a hyperventilation period or a post-hyperventilation period;

receive electroencephalography (“

EEG”

) data comprising a plurality of EEG channels, wherein each EEG channel of the plurality of EEG channels comprises a plurality of EEG instances;

receive video data of a subject from which the received EEG data is based;

correlate each EEG instance of the plurality of EEG instances to a respective portion of the video data in a database;

receive a first user input selecting a first EEG instance of the plurality of EEG instances;

in response to receiving the first user input, cross-reference the first EEG instance with the database to determine a first portion of the video data that corresponds to the first EEG instance;

correlate the data indicative of the at least one of the hyperventilation period or the post-hyperventilation period with at least one of the plurality of EEG instances or the first portion of the video data; and

generate for display, on a display device, the first portion of the video data, the plurality of EEG instances, and a graphic, separate from the plurality of EEG instances, that visually indicates a progression of the at least one of the hyperventilation period or the post-hyperventilation period correlated with the at least one of the plurality of EEG instances or the first portion of the video data.

12. The system for correlating brain activity to physical manifestations of claim 11, wherein the control circuitry is further configured to:

generate for display, on the display screen, a graphical representation of each EEG channel; and

overlay the first portion on the graphical representation of each EEG channel.
