Along the way you will learn a bit about the structure of sleep.
SLEEP EEG HOW TO
The methods used for analyzing sleep might also help you in characterizing drowsiness during a task, detect closed eyes or eye movements, detect spontaneous events in EEG (such as epileptic spikes) and in general how to include other modalities relevant to your task. Sleep is the most standardized and well-analyzed brain state to date. We will be using sleep recordings as an example for multimodal data and will form a picture of what is happening in the brain during sleep. You will learn how combining the modalities can give a better understanding of the brain states and the switching between them. In this tutorial you will explore and combine continuous EEG with multiple recordings from other modalities, such as muscles (EMG), eyes (EOG) and the heart (ECG).

With the help of an EEG, a doctor can help a patient effectively deal with a sleep disorder through a well-thought-out treatment plan. This is why an EEG is a helpful tool not just in diagnosing a sleep disorder but in pinpointing the cause of the disorder. Through the use of an EEG, it is possible to record brain waves that indicate whether a person is sleeping well or not. A sleep specialist can then isolate the source of the sleep disorder and formulate a treatment plan. By monitoring a rise or decline in Delta waves and cross-checking it with other factors that occur at the same time, a doctor can pinpoint an external factor that is preventing a patient from getting deep sleep. Delta waves indicate the deepest levels of relaxation and restorative sleep. This is why doctors also call Stage 3 of sleep as Delta Wave Sleep. In fact, the stages of sleep were first discovered via the use of EEG. Different brain activities correspond to different stages of sleep. The EEG readings can give a doctor a clearer picture of a patient’s sleep patterns. This is a non-invasive test and is safe even for children. While connected to an EEG, the sleep specialist monitors the stages of sleep of a patient. During the said test, a patient stays overnight in a medical facility. Doctors use EEG as part of a sleep study or polysomnography. On the other hand, a person with lesions on the brain may show unusually slow EEG waves.Īn EEG is also useful in diagnosing narcolepsy and insomnia. For example, rapid spiking waves on an EEG may indicate the presence of epilepsy. They are also printable so a patient can bring it to a healthcare provider for interpretation.Īn EEG is useful in evaluating several types of brain disorders. These charges appear as a graph viewed on a computer screen. The electrodes then detect tiny electrical charges produced from the activity of the brain cells. These electrodes have wires connected to a computer. This test uses electrodes made of small metal discs that get pasted on the scalp of the patient.
