Biofeedback & Neurofeedback System

 

eWave4s

 

Wireless , Light  and Low power

 

The eWave is a small and high-tech system for recording of EXG (EEG, ECG, EMG, EOG, ERP) signals in Biofeedback and neurofeedback applications.

The eWave amplifies bio signals by advanced and low noise amplifier and collects them by 2 to 128  channels of 24bit ADC 1K sample per second.

The DC coupled amplifiers record signals from 0Hz to 500Hz, including EEG, ECG, EMG, EOG and other DC signals.

The eWave transfers data to computer by Bluetooth wireless technology.

All of that combined with powerful eProbe software

Effective software for neurofeedback data Recording and analysis!

 

 

The eWave comes with the flexible and user friendly eProbe software. It offers clinicians and researchers lots of protocols for different types of treatment      and research strategies. 

 

  eProbe introduces you different components of the protocol that you can use during or after each session to play or analyze data.

 All You Need in Biofeedback Traning 

 

In eProbe, every page provides you with a context to add different components of the protocol. Here is a brief introduction of different components.

 

 

GAME

 

Play Video, Movie or Game

 

 

Game component enables clients to play video, movie or game.

It plays based on the client’s brain waves reflected on Bar panels and according to the features you have specifed.

Using this component, you can select the type of the game and the file that you want to display. You can also change the logic or rule of the play. 

 

 

 

SCOPE

 

See The Signal Both in Time and Frequency Domain

 

 

 

 

 

QEEG

 

Brain Map of a Specific Band 

 

 

 

 You can select one of the Gaussian, Cubic Spline or Linear Spline methods to calculate the QEEG.

 You can choose one of the predefined EEG bands on the setting table or enter a band in the forms of StartBand-StopBand.

 You may use one or multiple channels and put their leads on specific locations of the brain using 10/20 system. 

 

 

 

ANALYZE 

 

Analyze The Whole Data in Different Bands

 

 

 

After recording data you may need to see the whole data and analyze it.

eProbe provides you with a scope and a text panel to show the signal and the FFT power of each of the bands that you want.

You can select one or multiple bands and see the corresponding values in the text panel.

By default, this panel shows the latest file that you have previously recorded. But, you can change the analyze file and some other properties in the setting table.

 

 

 

FFT

 

The Online FFT Power of Your Desired Band

 

In FFT panel, you can see the square of the instantaneous FFT power of your desired band.  

You may want to see the FFT of specific EEG band or any other frequency band that you want.

You can choose one of the predefined EEG bands on the setting table or enter a band in the forms of Start Band - StopBand. 

 

 

 

BAR

 

The Colored FFT with A Threshold 


 

The Bar component calculates the square of the FFT power of the band that you have selected and displays it using a coloed bar.

It also shows weather this value is less or more than your desired threshold and considers it as a logic for the Game panel.

This logic is used in Game panel as a command or rule that determines how the game should play.

You can see both the value of the FFT power and the value of the logic in the Bar panel.

The FFT power is displayed in lower part of the bar and the logic is displayed in color form. It is green/red for upper than threshold and red/green for lower than threshold in Non Inverted/Inverted mode.

 

 

LIGHT

 

The Colored FFT with Two Thresholds 

 

Light component calculates the square of the FFT power of the band that you have selected and compares it with two thresholds.

If the value is more than both thresholds the light shows green color.

If it is less than both thresholds the color is red and if it is in the middle, the color is orange.

What is biofeedback?

What is biofeedback?

 Have you ever seen people who suffer from unwanted behavioral patterns but still refuse to see psychotherapists out of the fear of drugs and side effects? Have you ever looked for a noninvasive and drug free way to train the brain to self-regulate itself and improve your mood, behavior, learning patterns and physical symptoms? This is exactly where Neurofeedback comes in. Neurofeedback provides a safe way for people to improve their brain activity by training their wave brains, decreasing the power or amplitude of some undesirable frequency bands and increasing the desirable ones. Providing distinct protocol for each individuals by a therapist, Neurofeedback gives feedback to clients that how much they were successful in improving their brain waves by giving them a reward such as playing a movie or Game. Receiving appropriate feedback about its behavioral patterns, the automatic brain’s self-regulating organ is trained to correct itself and to strengthen its functionality.

 

 

How Does It Affect Brain?


 Is this like a fiction that a person can learn how to regulate his brain waves and promote his brain functionality? But you have experienced it before when you first learned how to ride a bicycle! That time, your brain learned how to self-regulate your state of balance during biking using the feedback it was being received from gravity. Just like your eyes who helped your brain learn how to bike, Neurofeedback send feedback to the person about his current brain status and how much it is in order using games and movies. It needs no effort from you, rather it is the central nervous system that decides to reorganize neural connections to modify the function of those parts. While you are seeing movie or playing games, your subconscious brain is going to modify itself based on the information it received during interruption in game or movie. For clients, it seems like a miracle when they saw how symptoms are diminished in their lives. This is the power of their brain that beyond their conscious awareness process more information than what their mind can handle from a software and constantly send commands to correct itself. Interestingly enough, this method has been both scientifically and empirically proved to be effective and has been increasingly practiced by specially trained psychotherapists.

Who Can Benefit?


 Everyone can benefit from neurofeedback therapy just like going to the gym that can be useful for anyone. It is practical for any age from children who suffer from learning problems to adults who like to be at their peak performance in their work and for elders who want to keep their brain abilities as they age. Neurofeedback can be used to improve attention, cognitive abilities, and emotional regulations. It has been used in numerous disorders including depression, attention deficit disorder, anxiety, sleep disorders, headaches and migraines, and other emotional issues. It can also be used for organic brain disorders, such as autism, cerebral palsy, seizures, stroke, and traumatic brain injury. It can also be helpful for people who struggle with drug and alcohol use and conditions like mood swings and PMS.

 

 

How Does It Work?

 

 

It works in some steps: 

•   The therapist provides a unique protocol for you according to your type.

•   He puts some sensors in specific location of your scalp to sense the electrical activity (known as EEG) of those particular parts of your brain.

•   You sit in front of a movie or game and very relax just see or play with your brain.

•   The software analyze your EEG signals to determine if your sate of the brain is in order or not or how much it is deviated from the normal.

•   The software gives you feedback about your brain status by stopping or resizing the movie or game. For example, whenever your brain waves are in order the movie is played with large screen giving your brain reward for its positive performance. Whenever it is out of order, the movie is stopped or its size is decreased.

•   The reminding happens automatically and unconsciously! No need for you to do anything else. Your brain do everything it needs to do! By using this feedback it realized that there is a problem in some parts of the brain and instantly tries to alter that!

•   Just wait and see how it creeps in your life and enhance your behaviors!
