Chapter 2 What is Schizophrenia condition?

Schizophrenia is a detrimental condition of the brain which leads to reduction in the cognitive awareness. The patients affected by this disease try to have impairment in assessing day-to-day activities. EEG is an important modality that can detect the SZ occurrence in an individual. The EEG signal shows low randomness compared to a healthy person. Here we will take few EEG signal of normal and SZ patients and analyse them.

2.1 Dataset

The SZ dataset which we are going to analyse here is from “EEG in schizophrenia (RepOD)” from the seminal works of (Olejarczyk and Jernajczyk 2017a). The dataset comprised 14 patients with paranoid schizophrenia and 14 healthy controls. Data were acquired with the sampling frequency of 250 Hz using the standard 10-20 EEG montage with 19 EEG channels: Fp1, Fp2, F7, F3, Fz, F4, F8, T3, C3, Cz, C4, T4, T5, P3, Pz, P4, T6, O1, O2. The reference electrode was placed between electrodes Fz and Cz.
