 If you are purchasing the Ganglion board, you will need the [Ganglion Dongle](https://shop.openbci.com/collections/frontpage/products/ganglion-dongle?variant=15473352605768).
 
-Now that you have the board, the second thing you need to get started is a set of electrodes (or a headset, we’ll talk about it after). Our Boards have male header connectors, so you would need to get electrodes that are compatible. If you are interested in mainly doing EMG or ECG, we recommend you use our [Snap Electrode Cables (EMG/ECG/EEG)](https://shop.openbci.com/collections/frontpage/products/snap-electrode-cables-emg-ecg-eeg?variant=32372786958) with [EMG/ECG Foam Solid Gel Electrodes](https://shop.openbci.com/products/kendall-emg-ecg-foam-solid-gel-electrodes-30-pack), these electrodes are a ready to go solution and plug in directly into our Biosensing boards. If you want to be able to do EEG as well as EMG and ECG, we recommend you get our [Gold Cup Electrodes](https://shop.openbci.com/collections/frontpage/products/openbci-gold-cup-electrodes?variant=9056028163) with [Ten 20 Paste](https://shop.openbci.com/collections/frontpage/products/ten20-conductive-paste-2oz-jars?variant=31373533198). You can affix these electrodes (almost) everywhere with some medical tape, which allows you to measure EEG, EMG, and ECG. If you already have your own electrodes, or have an electrode cap with touch proof connectors, you can still use them with our Biosensing Boards, by purchasing our [Header Pin to Touch Proof Electrode Adapter](https://shop.openbci.com/collections/frontpage/products/touch-proof-electrode-cable-adapter?variant=31007211715).

 Another way to go is to purchase the [Mark IV headset](https://shop.openbci.com/collections/frontpage/products/ultracortex-mark-iv). At its core the Mark IV is a frame with dry electrodes, that allows you to affix the dry electrodes to the scalp without having to use any paste. If you are mainly interested in EEG and do not want to have to go through the hassle of using EEG Paste on your hair, this is the way to go. You can purchase the Mark IV with either 8 electrodes or 16 electrodes (you don’t need to purchase extra electrodes). The Mark IV comes in 3 configurations, Print it Yourself, Unassembled, and Pro-Assembled. The Print it Yourself version is great if you have a 3D printer and you are able to print some of the parts yourself. The Print it Yourself version includes all of the electrodes, cables, and all of the other parts that aren’t 3D printable. The Unassembled version comes with all the necessary materials to build the headset, sort of like a puzzle but easier. You can check the [assembly guide](../AddOns/Headwear/01-Ultracortex-Mark-IV.md) for instructions. If you don’t want to bother with assembly or 3D printing parts, you can buy an already assembled headset, our Pro-Assembled Mark IV. Note that neither headset comes with a Biosensing board.
