title: Setting up for EEG, EMG, and ECG at the same time
---
-OpenBCI Cyton+Daisy board offers a wide range of flexibility with more signal channels.
-This tutorial will show you how to set up reading EEG (electroencephalography), EMG (electromyography),
-ECG (electrocardiogram) data at the same time.
-After going through this document, you will learn one configuration for setting up multiple ExG recordings
-at the same time. You could apply the same principle to build channel layouts to fit your application (i.e.,
-3-lead ECG vs. 5-lead ECG; eight or more EEG channels).

+The OpenBCI Cyton, Cyton+Daisy and Ganglion boards offer a wide range of flexibility to collect ExG signals. ExG is meant to represent any referential or differential biosignal as a single term. This includes EEG, EMG, EOG, ECG etc. This tutorial will show you how to measure EEG, ECG and EMG at the same time using the Cyton, Cyton+Daisy and Ganglion boards.

-Sometimes we use ECG and EKG interchangeably, as they are the same thing. This modality measures the electrical activity of muscles in the heart.
+ECG and EKG are used interchangeably and mean the same thing. Both terms measure the electrical activity of the heart muscles.

-## Materials Needed
+## Referential and Differential Signals with the ADS1299
+
+EEG, EMG, and ECG have different input requirements. This is because EEG is referential and EMG and ECG are differential. Referential biosignals are those that measure signals from an electrode location with a common reference point (like the earlobe). Differential biosignals are those that are localized to a certain area and the measured signal is the difference in voltage generated at that area. EEG is a referential signal because the signal is measured between an electrode location on the scalp and an electrically inert part of the head like earlobes, bridge of the nose etc. EMG and ECG are differential signals because two electrodes are used to measure the signal of a particular muscle on the body or heart.
+
+The labels for the channels can be found below the pin on the boards. Here we call BIAS and SRB the reference channels as they provide reference to the data channels. The data channels are N1P-N8P. The data streams come from the data channels. Each channel come with a top and bottom pin 
+
+Here are the reference channels needed for EEG, EMG, and ECG, respectively.
+
+- EEG: two reference channels - one SRB, and one BIAS
+- ECG and EMG: one reference channel - BIAS
+
+The BIAS and SRB are functions of the ADS1299 and this functionality provides the flexibility to measure differential and referential signals at the same time. SRB stands for Stimulus, Reference and Bias and acts as a common point for referential signals like EEG to compare against. SRB has two different pins on the ADS1299 - SRB1 and SRB2.
+
+SRB1 acts as a common reference for all the Positive inputs (meaning that it connects all the Negative inputs interally to the SRB1 pin) and SRB2 acts as a common reference for all Negative inputs (meaning that it connects all the Positive inputs internally to the SRB2 pin). To measure EEG with the Cyton and Cyton+Daisy, we use SRB2 as the common reference because it has the flexibility to be used individually for each channel instead of SRB1 which does not provide individual control. Therefore, the EEG measurements will look like (SRB2 - Negative Input) which is why the EEG signals might look inverted.
+
+BIAS on the other hand is used for noise-canceling due to connecting all Positive inputs to a common reference point. When doing this, a phenomenon called "Common Mode Noise" leaks into the board because multiple inputs are connected to the same point. Therefore, a BIAS connection to the body helps the ADS1299 account for this and a common mode voltage is subtracted from all measurements. It also helps in filtering out 50/60 Hz mains noise which is why we use it in all our referential and differential biosensing setups.
+
+For more information on SRB2, refer to Section 9.3.1.1 - Input Multiplexer and for more information on BIAS, refer to Section 9.3.2.4.5 - BIAS Drive of the [ADS1299 Datasheet](https://www.ti.com/lit/ds/symlink/ads1299.pdf?ts=1751268776160&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FADS1299%253FkeyMatch%253DADS1299%2526tisearch%253Duniversal_search%2526usecase%253DGPN)
+
+## ExG Measurement with Cyton+Daisy boards
+
+The Cyton and the Daisy boards both use the ADS1299 which makes this setup very simple and flexible. You just need to make sure that the settings in the OpenBCI GUI are correct so that the appropriate channels are configured properly. You can also setup just the Cyton to measure EEG, EMG and ECG but for simplicity, this section will use both the Cyton and the Daisy boards.
