Abstract:
The Gabor atom density (GAD) is a measure of complexity of a signal. It is based on the time-frequency decomposition obtained by the matching pursuit (MP) algorithm. The GAD/MP method was applied to EEG data recorded from intracranial electrodes in patients with intractable complex partial seizures. GAD shows that epileptic seizures, which are reflections of increased neuronal synchrony, are also periods of increased and changing signal complexity. The GAD/MP method is well suited to analyzing these signals from seizures characterized by rapid dynamical changes. The period of organized rhythmic activity exhibits lower complexity than that seen during other phases of the seizure.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
