Brain activity and how it works has been a core part of the medical community and researchers in recent years. EEG technology is a part of other complex technologies used to study the brain, its components, and its activities. The eeg cap is simple, affordable, alternative equipment that measures brain electrical activity.
EEG caps have a flat metal surface consisting of discs and several electrodes connected to the scalp to measure particular brain activity. It is a standard device people use to diagnose some brain disorders, including seizures and epilepsy. Additionally, EEG technology contributes to the treatment of various diseases and conditions.
Features and Working of An EEG Cap
Our brain comprises thousands of neurons that cause and show brain activity. There are multiple electrodes in an EEG cap since different sides of the brain produce a differing signals depending on the situation. Thus, a typical cap should have a minimum of 8 electrodes to make them practical for electrical activity measurement. Different brands produce caps with differing features, including electrodes.
The positioning of these electrodes is also essential, and the majority follow the standard quality guidelines. It is required for the headsets to have varying adjustable sizes that should be comfortable for a particular user. The cap should not be too tight or loose since it affects the results of the brain measurement. An essential part of the headset, however, is the signal. It usually is low before use and requires amplification before use.
Other Important Features
An EEG cap can either have dry or wet electrodes. Wet electrodes require a special gel, which can get messy and sticky. Hence, the most commonly used one is the dry electrode cap. Additionally, an EEG cap can be differentiated into wired or wireless caps. In most recent studies, wireless EEG caps are used because they are less bulky and more efficient.
How Is It Used?
1. A special pencil marks the scalp to indicate where the electrodes are placed.
2. An elastic cap is used to fit the electrodes to the scalp, which are then connected to the amplification and study device. The device records the waves on a computer.
During this time, a person must have their eyes closed while being comfortable. Taping and observation of behavior occur during this time. One session takes a maximum of forty minutes.
Usage in Diagnosing and Treatment
An EEG cap can diagnose or treat the following disorders.
1. Strokes
2. Sleep Disorders
3. Brain Inflammation
4. Brain Tumors
5. Brain damage and dysfunction
6. Confirmation of brain death for people in comas
Conclusion
Brain study is a fascinating area of research that has been gaining more traction in recent years. EEG caps are fantastic technology devices that provide simple, inexpensive ways for brain observation and studying. They have straightforward instructions on their usage and are a standard study method used in many brain research centers. Additionally, it has simple features of high functionality to depict electrical brain activity accurately. EEG is an excellent technology that furthers the medical research community.
