Area of Science:

Neuroscience
Biomedical Engineering
Signal Processing

Background:

Intracranial electroencephalography (iEEG) measures brain activity using electrodes placed directly on or within the brain.
iEEG offers superior signal-to-noise ratio compared to other electrophysiological methods.
Recordings are often obtained clinically for epilepsy monitoring, providing access to non-epileptic brain regions.

Purpose of the Study:

To describe the spatiotemporal dynamics of iEEG signals.
To highlight the utility of iEEG signals for decoding brain activity.
To demonstrate the potential of iEEG for driving brain-computer interfaces (BCIs).

Main Methods:

Analysis of iEEG signals in both the time and frequency domains.
Extraction of signal features such as evoked potentials, narrowband spectral peaks, and broadband power changes.
Characterization of signal dynamics across different brain regions, inputs, and tasks.

Main Results:

iEEG signals contain diverse features reflecting aggregate neuronal population activity.
Time-domain analysis can reveal event-related potentials.
Frequency-domain analysis identifies spectral peaks and broadband power changes associated with brain activation.

Conclusions:

iEEG provides a rich source of data for understanding human neurophysiology.
Specific iEEG signal features, particularly broadband power increases, correlate with brain region activity.
The spatiotemporal dynamics of iEEG signals are key to their application in brain-computer interfaces.
