Damage to the spinal cord disrupts the electrically active nerve cells which normally transmit afferent and efferent signals,resulting in loss of motor,sensory,and autonomic *** treatments for spinal cord injury utilizing implanted spinal electrodes can be broadly classified into three different *** first of these approaches is“spinal stimulation”where electrodes,usually positioned above the level of injury,provide electrical stimulation to target and disrupt pain signals before they reach the *** second approach uses“activity-dependent neuro-technologies”,in which electrodes positioned below the level of injury initiate a complex spatiotemporal pattern of stimulation at the lumbar spinal cord to generate a walking gait in the limbs(Minev et al.,2015;Wagner et al.,2018).

Growing up in rural Iowa, before I knew the word “agriculture,” I knew that producing food for people was part of Iowans’ identity. Before I learned the concepts of borders and nations, I knew people needed to be fed. It is a deep-rooted belief, and Iowans take great pride in producing abundant, high-quality food for the world. It was no surprise that I chose agriculture for my college education and have continued down this path for my career.
