<description>This list contains EEG analysis software that can import Mentalab Explore data.
In general, many EEG analysis pipelines use EDF file formats. To convert your Mentalab Explore data to EDF, please use the bin2edf command available in our open source API explorepy. If your device has internal memory, it will automatically save data to BIN. If you are using the Bluetooth feature of your Mentalab Explore device, be sure to record to BIN and not CSV on the connected device.</description>

<description>Operating modes Mentalab Explore+ has two main operating modes: offline and online. When in offline mode, the amplifier collects data and stores it in internal flash memory. Users can extract the recordings from the memory using a USB-C cable after recording. In online mode, data is transmitted via Bluetooth in real-time to a host machine, enabling the user to collect, monitor, and visualize data. In this mode, you can also measure impedances, and configure the amplifier with explorepy and exploreAndroid.</description>

<description>Here is a step-by-step guide on using explorepy and OpenViBE to visualize multiple Mentalab Explore systems simultaneously.
Start two Python consoles and activate a virtual environment for explorepy in both.
Use the push2lsl command to stream data from your Explore device to lab streaming layer (one device per console).
Open an OpenViBE acquisition server and select &ldquo;LabStreamingLayer&rdquo; as the driver. Under &ldquo;Driver Properties&rdquo;, select your Explore device&rsquo;s &ldquo;ExG&rdquo; and &ldquo;Marker&rdquo; streams, selecting only one of the connected Explore devices.</description>

<title>Dry Electrode Guide</title>
<link>https://wiki.mentalab.com/user-guide/dry-electrode-guide/</link>
<pubDate>Wed, 26 Jan 2022 10:25:19 +0000</pubDate>
<guid>https://wiki.mentalab.com/user-guide/dry-electrode-guide/</guid>
<description>Dry electrodes types Mentalab currently offers three types of dry electrodes.
Flat electrodes For electrode positions not covered by hair (e.g. on the forehead, mastoid…), our flat electrodes ensure optimal skin contact and comfort.
Brush electrodes Dry brush electrodes.
For areas covered in hair, we recommend using brush electrodes. Their flexible pins penetrate most hair types and establish good contact with the scalp. XL brush electrodes For very dense and curly hair types, we recommend using our XL brush electrodes for increased hair penetration.</description>

<guid>https://wiki.mentalab.com/applications/photodiode-event-trigger/</guid>
<description>Synchronizing ExG signals with stimuli is critical to many research paradigms. There are two main approaches to synchronizing data: software event markers and hardware triggers.
Although software event markers are easy to use, they are not as precise as hardware triggers. This is because the data is sent via Bluetooth, which has some inherent delays.
Meanwhile, hardware triggers are much more precise but involve connecting a wire between devices (e.g. a computer and an Explore device).</description>

<title>SSVEP Experiments</title>
<link>https://wiki.mentalab.com/applications/ssvep/</link>
<pubDate>Wed, 26 Jan 2022 10:25:19 +0000</pubDate>
<guid>https://wiki.mentalab.com/applications/ssvep/</guid>
<description>Steady state visually evoked potentials (SSVEPs) are commonly used in neuroscience and BCI research.
SSVEPs are brain signals that occur in response to a visual stimulus flickering at a fixed frequency (typically 3-75 Hz). A rhythmic stimulus can entrain brain activity in the occipital lobe, which is commonly associated with the visual cortex.
Here, we show you how to use Mentalab Explore with SSVEP-based classification tasks. The code is open-source and available here.</description>

<title>Improving Impedances</title>
<link>https://wiki.mentalab.com/user-guide/improving-impedances/</link>
<pubDate>Tue, 25 Jan 2022 16:17:02 +0100</pubDate>
<guid>https://wiki.mentalab.com/user-guide/improving-impedances/</guid>
<description>Since the impedance at the REF electrode affects signal quality for all EEG channels, we recommend starting with the REF electrode.
General Always verify that there is good contact between electrode and scalp. Ensure all electrodes are being pulled into the scalp by the cap and there are no creases in the cap causing electrodes to “float&quot;.
A thin, elastic cap placed over the electrode cap can further reduce impedances. It presses gently on all electrodes, particularly in occipital positions.</description>

<description>The 12 lead electrode configuration. Source: CardioSecur Conventional 12-lead ECG uses 10 electrodes (6 electrodes on the chest and 4 electrodes on the limbs&rsquo; extremities).
Although it provides comprehensive information about electrical processes inside the heart, the number of electrodes and the long distance between them makes 12-lead ECG impractical and uncomfortable. This is especially true if the participant must remain still for a lengthy recording sessions.
