EEG electrodes are indispensable accessories for the exam, as they capture the electrical impulses emitted by the brain. Connected to the monitor of the electroencephalogram device , these small pieces transmit the signals, allowing their conversion into line graphs. However, care must be taken. When cleaning and applying the electrically conductive paste, avoiding artifacts that impede the interpretation of the exam. I discuss these precautions throughout this text, including guidelines for placing. EEG electrodes correctly . Read to the end and learn about the advantages of telemedicine for issuing online reports for the electroencephalogram. What are EEG electrodes? EEG electrodes are small devices that connect to the monitor of EEG equipment. The parts are responsible for collecting spontaneous electrical currents emit by the neurons during the exam, sending them to the monitor.
This makes the electrodes essential for
They are glue to the patient’s scalp. Capturing the electricity that will be filter and amplified for its recording in the form of brain waves. Generally, the test is perform during wakefulness, drowsiness and sleep. In order to allow the comparison of the different waves to normality patterns. It is also common to carry out maneuvers that provoke reactions Spain Phone Numbers List of certain groups of neurons. One of them is hyperventilation, trigger by accelerate breathing during the EEG. Photostimulation is generate using equipment called a stroboscope. Which produces strong, flashing lights in front of the patient. The electroencephalogram perform by general practitioners or specialists , or even nursing technicians who have specific training. Types of EEG Electrodes. Different types of electrodes for EEG are available on the market, most of which need conductive paste or gel to ensure adherence to the scalp. There are options with different formats and even disposable ones. Some types of EEG electrodes.
Passive electrode these are quite popular
Consisting of a piece coated in silver and connected to an individual wire that leads to the EEG monitor. Requires conductive gel to enable the capture of electrical signals Active electrode : with advanced technology, this type of electrode does not require conductive paste . Its active circuits facilitate the recording of electrical impulses, reducing ambient noise. Dry electrode : decreases the time need DT Leads to prepare the patient before the EEG. The dry electrodes are connected through a type of helmet that can be adjusted to the size and shape of the patient’s head. As the name suggests, they do not use electrically conductive gel Sponge electrode : it also does not need gel, as its format allows for high adherence to the scalp . It is usually used when the electroencephalogram uses a large number of channels (from 32 to 128, depending on the device). Next, I explain how to place.
