A team of researchers has taken a key step toward a new concept for a future BCI system — one that employs a coordinated network of independent, wireless microscale neural sensors, each about the size of a grain of salt, to record and stimulate brain activity. The sensors, dubbed “neurograins,” independently record the electrical pulses made by firing neurons and send the signals wirelessly to a central hub, which coordinates and processes the signals.<br /><br />Credit: Jihun Lee / Brown University<br /><br />Research paper: Neural recording and stimulation using wireless networks of microimplants <a href="https://www.nature.com/articles/s41928-021-00631-8" target="_blank" rel="nofollow">https://www.nature.com/articles/s41928-021-00631-8</a><br /><br />News Source: <a href="https://www.eurekalert.org/news-releases/925219" target="_blank" rel="nofollow">https://www.eurekalert.org/news-releases/925219</a><br /><br />Playlist for Technology News Videos - <a href="https://www.youtube.com/playlist?list=PLK2ccNIJVPpB_XqWWq_oaZGIDzmKiSkYc" target="_blank" rel="nofollow">https://www.youtube.com/playlist?list=PLK2ccNIJVPpB_XqWWq_oaZGIDzmKiSkYc</a><br />Health - <a href="https://www.youtube.com/playlist?list=PLK2ccNIJVPpArLvIQIPxIkHzcSg6qPm0T" target="_blank" rel="nofollow">https://www.youtube.com/playlist?list=PLK2ccNIJVPpArLvIQIPxIkHzcSg6qPm0T</a><br />...<br /><a href="https://www.youtube.com/watch?v=s7QAQd4ViA0" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=s7QAQd4ViA0</a>
