Intracranial Electroencephalography (iEEG)

Intracranial EEG (iEEG) is a neurophysiological monitoring technique that involves placing electrodes directly on the exposed surface of the brain to record electrical activity. This method provides highly localized and detailed information about brain function, making it invaluable for diagnosing and treating neurological disorders, such as epilepsy. By capturing the brain's electrical signals with exceptional spatial resolution, iEEG helps clinicians pinpoint the exact regions responsible for abnormal activity, guiding surgical interventions and other treatments. Although it is more invasive than other neuroimaging techniques, its precision and depth of information are unmatched.

Scalp Electroencephalography (sEEG)

Scalp EEG (sEEG) is a non-invasive method for recording the brain's electrical activity using electrodes placed on the scalp. This technique is widely used in clinical and research settings to monitor brain function, diagnose conditions like epilepsy, and study cognitive processes. While it offers less spatial resolution compared to intracranial EEG, sEEG is safer and more accessible, making it suitable for a broader range of applications. By analyzing the brain's electrical rhythms, sEEG can provide valuable insights into various neurological conditions and help guide treatment decisions.

Magnetoencephalography (MEG)

Magnetoencephalography (MEG) is a sophisticated neuroimaging technique that measures the magnetic fields produced by neuronal activity in the brain. Unlike EEG, which records electrical signals, MEG captures the magnetic counterparts, offering complementary information about brain function. MEG is non-invasive and provides excellent temporal resolution, allowing researchers and clinicians to track brain activity in real-time. This technique is particularly useful for mapping brain function before surgery, studying sensory processing, and investigating cognitive and neurological disorders. By combining MEG data with other imaging modalities, such as MRI, researchers can gain a comprehensive understanding of the brain's structure and function.
