Lower left: micro-CT image of unwired MINA chronically implanted in rodent vagus. Lower right: surgical image of MINA being inserted into nerve and example of intraneural action potential recorded with MINA.

ALT Graphical abstract of paper, showing carbon fiber array and example neural waveforms. Paper title: Multi-channel intraneural vagus nerve recordings with a novel high-density carbon fiber microelectrode array. Image text: Autonomic nerves convey neural signals that regulate vital body functions. Recording these signals is difficult and rarely achieved. We developed the carbon fiber microelectrode array (CFMA) for autonomic nerves. CFMA recorded clear action potential signals in spontaneous and modulated conditions.
