Electrical impulses recorded with 3D-printed device

A team of scientists from the University of Oregon (OR, USA) has 3D printed a device to house an electrode capable of ‘exciting’ nerves. When implanted into the peripheral nervous system of a songbird, the bioelectronic device was able to record electrical impulses that drive vocalizations and researchers have also been able to precisely control the output of the associated nerve in male zebra finches. Results, outlined in Nature Communications, have encouraged researchers to believe that this research could lead to advances in treatments for diseases such as inflammatory bowel syndrome, rheumatoid arthritis and diabetes as the field of bioelectronic...
