Fundamentals of EEG Signal Processing
2 Fundamentals of EEG Signal Processing EEG signals are the signatures of neural activities. They are captured by multiple-electrode EEG machines either from inside the brain, over the cortex under…
EEG Source Localization
5 EEG Source Localization 5.1 Introduction The brain is divided into a large number of regions, each of which, when active, generates a local magnetic field or synaptic electric current….
Event-Related Potentials
3 Event-Related Potentials Event-related potentials (ERPs) were first explained in 1964 [1,2], and have remained as a useful diagnostic tool, in both psychiatry and neurology. In addition, they have been…
Seizure Signal Analysis
4 Seizure Signal Analysis An original impression and the fundamental concepts of epilepsy were refined and developed in ancient Indian medicine during the Vedic period of 4500–1500BC. In the Ayurvedic…
Brain–Computer Interfacing
7 Brain–Computer Interfacing Brain–computer interfacing (BCI) (also called brain–machine interfacing (BMI)) is a challenging problem that forms part of a wider area of research, namely human–computer interfacing (HCI), which interlinks…
Introduction to EEG
1 Introduction to EEG The neural activity of the human brain starts between the 17th and 23rd week of prenatal development. It is believed that from this early stage and…
9: Myocardial Ischemia and Necrosis
Myocardial Ischemia and Necrosis 9.1. Introduction Table 9.1 shows the various clinical presentations with ECG abnormalities due to myocardial ischemia and/or necrosis. These ECG disturbances occur mainly in the T wave,…
2: The ECG Curve: What Is It and How Does It Originate?
The ECG Curve: What Is It and How Does It Originate? 2.1. How Does the TAP of a Myocardiac Cell Become the Curve of the Cellular Electrogram? The electrical activity (depolarization…
4: ECG Interpretation
ECG Interpretation 4.1. A Systematic Method of Interpretation The routine use of a systematic method of interpretation for both normal and pathologic ECG patterns as outlined below, is an effective way…
