Article Figures & Data
Figures
- Figure 1
Desynchronization (generalized electrodecremental ictal pattern) associated with epileptic spam.
- Figure 2
There is a new rhythm medium amplitude alpha frequency 9Hz arising from right temporal T4 with evolution to higher amplitude and slower in frequencies which is representing an ictal discharge.
- Figure 3
Hypsarrhythmia, which is a continuous, high amplitude, asynchronous delta activities with interspersed independent multifocal spikes
