There are many Biosignal, which can be obtained from our human body, among that EEG (Electroencephalography) wave which is obtained from the Brain. EEG is the wave, which is generated by the electrical activity, which is happening in our Neurons. There are Five EEG Bands which lies in different frequencies they are,
- DELTA – 0 to 3 Hertz Frequency
- THETA – 3 to 8 Hertz
- ALPHA -8 to 12 Hertz
- BETA – 12 to 27 Hertz
- GAMMA – 27 to 100 Hertz of Frequency
Block diagram description
In the above Block diagram, Brainsense is fixed in the Head, which is connected, to the Matlab by connecting the Device with the Laptop/PC via Bluetooth. Matlab process and analyze to results the different bands of the EEG signal.
Extracting Brainwaves from the Brain using Mindwavemobile/Brainsense process which is known as Signal Acquisition. After it is obtained from the Brain it gets processed using Matlab for various analysis which is known as Signal Processing. Thus this project results in the various EEG bands which gets processed from our Brain signal.
- Raspberry Pi
- Power Adapter
- HDMI to VGA converter (optional, when connecting to Monitor)
- Matlab (32-bit)
Each EEG bands resulting in some of the activities of Brain like Activeness, Drowsiness, Deep sleep by analyzing that parameter will be used for research purpose for several applications
