The morphology of a waveform describes its overall shape, and is important for both interpreting a tracing and communicating your findings. For an individual waveform, each part of a wave is considered a phase.
Neurons communicate through a combination of chemical neurotransmitters and electrical gradients, and electroencephalography, or EEG, detects those electrical gradients to provide insight into the activity of the brain.
Neurons come in different shapes and sizes – but they do share a similar structure: a cell body (soma) that extends into axons and dendrites. Dendrites and axons in turn contain synapses, which are highly specialized junctions connecting two neurons [2][18].
Study with Quizlet and memorize flashcards containing terms like Describe the steps for analyzing EEG data to determine the frequency of the different brain waves using the "I" beam., What does EEG stand for?, Describe the color, polarity, and location of each lead for the EEG experiment. and more.
Analysis of EEG Activity: What does it mean? What is the source? What is the significance? - What is the ordering provider’s question, and how may I best answer it with my EEG interpretation? -Is this record normal or abnormal? -If abnormal, is the abnormality focal or generalized?
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. 2. Sensitivity. 3 . Filters.
An interactive, modular course for learning how to read electroencephalograms (EEG).
