An EEG is a scalp recording of brain wave activity. The brain wave activity recorded is a summation of the inhibitory and excitatory post synaptic potentials that occur across a neuron membrane. That’s all good but how the heck do I read an EEG!? First know what you are looking at on the screen. 1. Montages. Electrodes. Channels. Bipolar Montage.
Electroencephalograms (EEGs) are ubiquitous in clinical neurology. They are used to evaluate transient neurological symptoms such as impaired awareness, altered sensations, or abnormal movements. They form a part of the evaluation of common neurological illness such as epilepsy, stroke, tumors, dementia, encephalopathy, and encephalitis.

EEGs are a simple and commonly used neurological test that most trainees find hard to interpret. Summations of excitatory and inhibitory postsynaptic potentials of pyramidal neurons in the superficial layers of the cortex generate electrographic activity.
This book has three parts that should be read sequentially. Part I (Basics) equips the reader with the foundational knowledge necessary to begin reading EEGs. It consists of chapters dedicated to understand-ing the technical aspects of interpretation and the normal EEG. Part II (Interpretation) is dedicated to EEG reading through a step wise ...
Describe cerebral activity based on its location (general or lateral), occurrence (sporadic or repetitive), and morphology (slow or sharp). Then categorize the activity as normal (normal variant) or abnormal. Decide if the abnormality is epileptogenic (associated with seizures) or ictal (ongoing seizure).
The EEG is an electrophysiological technique for the recording of electrical activity arising from the human brain. Given its exquisite temporal sensitivity, the main utility of EEG is in the evaluation of dynamic cerebral functioning.
