<guid>https://wiki.mentalab.com/user-guide/operating-instructions/</guid>
<description><h2 id="operating-modes">Operating modes</h2>
<ul>
<li>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.</li>
<li>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 <a href="https://wiki.mentalab.com/explore-desktop-guide/">Explore Desktop</a>, <code>explorepy</code>, or <code>exploreAndroid</code>. In online mode, the Explore amplifier sends signal data to the host machine. It also sends meta-data when the amplifier’s settings change.</li>
<li>We recommend charging the amplifier for at least one hour before first use. To charge the amplifier, connect the USB-C cable to a compliant source. A green LED indicates sufficient battery (&gt; 60% charge). After charging, unplug your amplifier from the power source.</li>
</ul>
<h2 id="pre-experiment-checklist">Pre-experiment checklist</h2>
<p>We strongly recommend completing this checklist before you start collecting EEG data. This will ensure you get the best out of your Explore system.</p></description>

<description><h2 id="dry-electrodes-types">Dry electrodes types</h2>
<p>Mentalab currently offers three types of dry electrodes.</p>
<h3 id="flat-electrodes">Flat electrodes</h3>
<p>For electrode positions not covered by hair (e.g. on the forehead, mastoid…), our flat electrodes ensure optimal skin contact and comfort.</p>
<h3 id="brush-electrodes">Brush electrodes</h3>

<img class="mobile" src="https://wiki.mentalab.com/img/UserGuide/brush-electrodes.jpg" alt="Brush electrode" width=400/>
<figcaption> Dry brush electrodes.</figcaption>
</figure>
For areas covered in hair, we recommend using brush electrodes. Their flexible pins penetrate most hair types and establish good contact with the scalp. 
<h3 id="xl-brush-electrodes">XL brush electrodes</h3>
<p>For very dense and curly hair types, we recommend using our XL brush electrodes for increased hair penetration.</p></description>

<title>Photodiode Event Triggers</title>
<link>https://wiki.mentalab.com/applications/photodiode-event-trigger/</link>

<guid>https://wiki.mentalab.com/applications/photodiode-event-trigger/</guid>
<description><p>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.</p>
<p>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.</p>
<p>Meanwhile, hardware triggers are much more precise but involve connecting a wire between devices (e.g. a computer and an Explore device). This means your Mentalab Explore system is no longer fully wireless (although presenting stimuli on a mobile can mitigate this).</p></description>

<p>Record data in real time to EDF (BDF+) or CSV by selecting ‘Record’ on the Visualization page.</p>
<p>A pop-up will allow you to configure your recording.</p>
<p>Settings include:</p>
<ul>
<li>File format – select the output file type (EDF or CSV):
<ul>
<li>CSV mode generates an extra file for the marker events</li>
<li>BDF mode records data in BDF+ format (in 24-bit resolution)</li>
</ul>
</li>
<li>Folder and name prefix – select where to store files and the file prefix.	For example, if the prefix is ‘test’, data will record in 	three separate files: ‘test_ExG.csv’, ‘test_ORN.csv’, and ‘test_Marker.csv’. These files will contain ExG data, orientation data, and event markers.</li>
<li>Recording time (in seconds) – set the duration of the recording. You can stop recording at any time by clicking ‘Stop’.- Filters.</li>
</ul>

<div class="alert alert-info" role="alert">
 You can inspect ongoing recording while recording. Go to Tools-&gt; Inspect ongoing recording. Then zoom in/out with mouse hover on X or Y axis
</div>


<div class="alert alert-info" role="alert">
 Because environmental factors, like temperature, can affect your sampling rate, we recommend computing the sampling rate of your recorded data. If you find a deviation between the sampling rate you calculate and Explore Desktop’s sampling rate, resample your signal to correct for drifts. The timestamps in the CSV/EDF file can be used to compute the resampling factor.
</div>


<div class="alert alert-info" role="alert">
 If you are setting markers in your recording, record to CSV. Alternatively, push data to LSL and record with LabRecorder. EDF cannot guarantee precise marker timings.

<h2 id="event-markers">Event markers</h2>
<p>One method to generate a marker event is to press the button on your Mentalab Explore device. Alternatively, you can set event markers using the ‘Set’ button.</p></description>

<description><p>Steady state visually evoked potentials (SSVEPs) are commonly used in neuroscience and BCI research.</p>
<p>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.</p>
<p>Here, we show you how to use Mentalab Explore with SSVEP-based classification tasks. The code is open-source and available <a href="https://github.com/Mentalab-hub/explorepy/tree/master/examples/ssvep_demo">here</a>. You can run it as is or use it to build your own SSVEP based applications.</p></description>

<description><p>Since the impedance at the REF electrode affects signal quality for all EEG channels, we recommend starting with the REF electrode.</p>
<h2 id="general">General</h2>
<p>Always verify that there is good contact between electrode and scalp. Ensure all electrodes are being pulled onto the scalp by the cap and there are no creases in the cap causing electrodes to “float&quot;.</p>
<p>A thin, elastic cap placed over the electrode cap can further reduce impedances. It presses gently on all electrodes, particularly in occipital positions.</p></description>

<p>Conventional 12-lead ECG uses 10 electrodes (6 electrodes on the chest and 4 electrodes on the limbs&rsquo; extremities).</p>
<p>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.</p>

<description><p>This is a step-by-step guide describing how you can get the most out of your EEG sleep recording using Mentalab Explore.</p>

<div class="alert alert-info" role="alert">
 Battery life is affected by sampling rate and Bluetooth connection. To maximize your recording time, we recommend offline recording at 250Hz.
</div>

<h2 id="setting-up-your-mentalab-system">Setting up your Mentalab system</h2>
<ol>
<li>Fully charge your amplifier then disconnect it from the USB port.</li>
<li>Set up your participant&rsquo;s cap and electrodes.</li>
<li>Open <a href="https://wiki.mentalab.com/explore-desktop-guide/">Explore Desktop</a> and connect your amplifier to your computer via Bluetooth.</li>
<li>Check your system&rsquo;s impedances using Explore Desktop. If you need to improve your impedances, please consult: our guide on <a href="https://wiki.mentalab.com/user-guide/improving-impedances/">improving impedances</a>, our <a href="https://wiki.mentalab.com/user-guide/eeg-pre-experiment-checklist/">pre-experiment checklist</a>, and our <a href="https://wiki.mentalab.com/user-guide/dry-electrode-guide/">dry electrode guide</a>.</li>
<li>End Explore Desktop&rsquo;s impedance mode and go to the <a href="https://wiki.mentalab.com/explore-desktop-guide/usage/#configuration">Configuration page</a>. Name your channels and apply the changes.</li>
<li>Format your memory, and disconnect from Bluetooth. Your device should be blinking green. This indicates that it is recording in offline mode.</li>
<li>Go to sleep! (And try to avoid moving the electrodes.)</li>
</ol>
<h2 id="exporting-your-data">Exporting your data</h2>
<ol>
<li>Ensure that your amplifier is turned off (no blinking of any kind).</li>
</ol>

<div class="alert alert-danger" role="alert">
 Connecting your amplifier to a USB port while it is still recording will corrupt the data. Always make sure your device is powered off before connecting it via USB to another system.
</div>


<div class="alert alert-info" role="alert">
 If your amplifier is still recording (offline), it will blink green intermittently. Hold the amplifier&rsquo;s button to power off (you will see three red blinks followed by no blinks at all).
</div>

<ol start="2">
<li>Disconnect the electrodes from your amplifier.</li>
<li>Connect your amplifier to a computer using the provided USB cable.</li>
<li>Export the largest <code>BIN</code> file you can see on the internal memory.</li>
<li>Convert the <code>BIN</code> file to an appropriate file type using Explore Desktop&rsquo;s File menu (top left corner).</li>
<li>Finally, charge your amplifier and clean your cap and electrodes thoroughly. For more on cleaning, see our <a href="https://wiki.mentalab.com/user-guide/cleaning-disinfection-storage/">cleaning guide</a>.</li>

<title>Sleep EEG Analysis</title>

<description><p>Modern sleep science is fundamentally informed by ExG biosensors recording brain activity (electroencephalography, EEG), eye-movement activity (electrooculography, EOG), and muscle activity (electromyography, EMG) to characterize the physiology of sleep.</p>
<p>Here, we demonstrate how EEG data recorded during a full night&rsquo;s sleep using Mentalab Explore can be analysed with the free and open source <a href="https://raphaelvallat.com/yasa/build/html/index.html">yasa toolbox</a>. We will perform automatic sleep staging by applying the yasa classifier <a href="#references">[1]</a> to EEG data, inspect band power in the EEG signal, and detect slow waves and sleep spindles. The application example follows the excellent <a href="https://github.com/raphaelvallat/yasa/tree/master/notebooks">yasa notebooks</a>.</p></description>

<description><p><a href="https://www.eegsynth.org/">EEGSynth</a> is a software project aiming at connecting brain signals to electronic music instruments. EEGSynth is taking inspiration from <a href="https://en.wikipedia.org/wiki/Modular_synthesizer">modular synthesizers</a>. In a modular synth, each module performs a specific function (generating sound, modulating sound, generating control voltages, etc.) and outputs from one module can be connected to the inputs of another module using patch cables. The entirety of the connected modules is referred to as a patch.
Similarly, EEGSynth modules can, among many other things, take in real-time EEG signals, process them and extract useful information such as bandpower, and use these to send instruction messages to electronic music instruments using the MIDI standard.</p></description>
