The evolution with time of the spatial distribution of the largest Lyapunov exponent on the human epileptic cortex

  title={The evolution with time of the spatial distribution of the largest Lyapunov exponent on the human epileptic cortex},
  author={Leonidas D. Iasemidis},
The topic of this presentation is the investigation of the epileptic human brain as a nonlinear system that undergoes a phase transition (epileptic seizure). The estimated values of the largest Lyapunov exponent L over time indicated a more chaotic state postictally than ictally or preictally. The start of a seizure corresponds to a simultaneous drop in the values of L at the focal electrode sites. The observed slow cyclic variations in the temporal Lyapunov profiles imply attempts of the… CONTINUE READING
