The EEG is a medical device used to map the brain function of patients. It is a non-invasive, non-ionizing device that captures brain waves to diagnose neurological diseases and disorders. With the help of the EEG, doctors can monitor brain activity in chronic epileptic patients.
EEG is a graphical representation of the electrical activity of the brain. This activity is measured by electrodes placed on the scalp. It is used to diagnose and monitor a variety of brain disorders.
– EEG technology is relatively inexpensive and easy to use, making it a common tool in neurology clinics.
– EEGs can be used to track the progress of a patient’s condition and to assess the effectiveness of treatment.
– EEG technology does not provide images of the brain, so it cannot be used to diagnose conditions that are visible on imaging scans.
– EEGs can be affected by a number of factors, including muscle activity, the type of electrode used, and the patient’s medication.
What Happens During an EEG?
To measure the electrical activity of the brain, small metal discs called electrodes are placed on the scalp. These electrodes pick up the electrical signals from the brain and send them to a machine that records them.
What Happens after an EEG?
The EEG technician will print out the results of the test and give them to the doctor. The doctor will review the results and determine if any additional testing or treatment is needed.
EEG Basic Working Principle
The EEG measures the summed electrical activity of large numbers of neurons in the cortex. The cortex is a sheet of neural tissue that covers the brain. The EEG signal is a mixture of the signals from all of the neurons in the cortex.

How is an EEG done?
Electrodes are placed on your scalp to measure the electrical signals that are generated when your brain cells communicate with each other. The signals are measured in units called microvolts.
An EEG can be used to help diagnose problems with the brain, such as seizures, head injuries, and problems with the blood flow to the brain. It can also be used to help diagnose problems with the way the brain is working, such as in people with dementia, Alzheimer’s disease, and other types of dementia.
Types of EEG
EEG signal is the electrical activity of the brain that can be detected by electrodes placed on the scalp. The EEG signal is a sum of the potentials generated by the synchronous firing of millions of neurons.
EEG signals are classified into five main types:
1. Delta waves: These are the slowest waves, with a frequency of less than 4 Hz. They are associated with deep sleep.
2. Theta waves: These are also slow waves, with a frequency of 4-8 Hz. They are associated with drowsiness and light sleep.
3. Alpha waves: These are medium-frequency waves, with a frequency of 8-12 Hz. They are associated with relaxation and calmness.
4. Beta waves: These are the fastest waves, with a frequency of 12-38 Hz. They are associated with concentration and alertness.
5. Gamma waves: These are the fastest and highest-frequency waves, with a frequency of more than 38 Hz. They are associated with cognitive processing and learning.
Neurostyle is a growing EEG machine brand. Instead of capturing ideas or emotions, our EEG equipment tracks variations in the electrical activity the brain generates. Ionic current within and between neurons is what causes these voltage variations. EEG devices record electrical signals that naturally occur while your brain assimilates and analyses information rather than delivering electricity to your brain.
