Large-scale, long-term recordings of the activity of individual brain neurons are essential for improving our knowledge of neural circuits, developing new medical device-based treatments, and, eventually, developing brain-computer interfaces that need high-resolution electrophysiological data.

Recording the activity of large populations of single neurons in the brain over long periods of time is crucial to further our understanding of neural circuits, to enable novel medical device-based therapies and, in the future, for brain–computer interfaces requiring high-resolution electrophysiological information.

<p>An interdisciplinary team of researchers from the&nbsp;<a href="https://seas.harvard.edu/">Harvard John A. Paulson School of Engineering and Applied Sciences&nbsp;</a>(SEAS), in collaboration with The University of Texas at Austin, MIT and&nbsp;<a href="https://axoft.us/" target="_blank">Axoft, Inc</a>., developed a soft implantable device with dozens of sensors that can record single-neuron activity in the brain stably for months.</p>

"Hey, Siri, how's the weather today?" Voice recognition technology is increasingly prevalent in our daily lives, from asking trivial questions, playing music, sending text messages to controlling GPS navigation systems.
