By nature, EEG signals are considered non-stationary due to their time-varying characteristics caused by factors like brain state changes and electrical artifacts. This non-stationarity makes it challenging to analyze EEG data using traditional stationary signal processing techniques and often requires specialized methods such as time-frequency analysis.

What is a non stationary signal?

A non-stationary signal is one whose frequency changes over time; e.g. human speech where frequencies vary over time depending on what words or syllables you are pronouncing. On the contrary, you have stationary signals where frequencies don't change over time; e.g. the signal: cos(20*pi*t)+cos(50*pi*t)+cos(200*pi*t) where all of the frequency components (20*pi, 50*pi, 200*pi) exist at all times.


Is it possible to measure eeg waves from a different room?

Yes, it is possible to measure EEG waves from a different room using wireless EEG systems that can transmit data in real-time to a monitoring system in another room. This allows for increased flexibility and convenience in conducting EEG measurements.


How does a Doppler radar differentiates a stationary target from a moving target using Doppler effect?

A Doppler radar differentiates a stationary target from a moving target by measuring the change in frequency of the reflected signal. For a stationary target, there is no change in frequency, while for a moving target, there is a shift in frequency due to the Doppler effect. By analyzing this frequency shift, the radar can determine whether the target is moving or stationary.


Which Equipment is used to monitor brain waves?

An electroencephalogram (EEG) machine is used to monitor brain waves. This device records the electrical activity of the brain by attaching electrodes to the scalp, which can help in diagnosing conditions such as epilepsy, sleep disorders, and brain injuries.

What is an artifact in an EEG?

In an EEG, an artifact refers to any abnormal signal that is not produced by brain activity, such as muscle movements, eye blinks, or external interference in the recording. Artifacts can affect the accuracy of the EEG readings and may need to be identified and removed during data analysis.


What does synchrony in eeg mean?

Synchrony in EEG refers to the coordinated activity of brain regions measured by the EEG signal. It indicates when different parts of the brain are communicating and working together in a synchronized manner, which is important for various cognitive functions such as attention, memory, and perception. Deviations in synchrony patterns may be linked to neurological and psychiatric disorders.


How can one learn to read EEG brain waves effectively?

Learning to read EEG brain waves effectively involves obtaining specialized training in neuroscience and electrophysiology. This typically includes studying the principles of EEG signal processing, understanding the different brain wave patterns, and gaining practical experience in interpreting EEG data through hands-on practice and mentorship. Additionally, staying updated on the latest research and advancements in the field can help improve proficiency in reading EEG brain waves.
