Abstract:
The present study describes the electroencephalography and the physical characteristics relevant to a quantitative description of the electrical and magnetically fields generated in the brain are reported. The models used to resolve the problem associated with cerebral anisothropy are cited. The registers reference-free are analyzed, and the origin of electrical activity in the brain is summarized briefly from cellular and chemical-physical perspectives.

An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin to...
