Normann, Richard A.; Clark, Gregory A.; McDonnall, Daniel | Selective motor unit recruitment via intrafascicular multielectrode stimulation | Recruitment of force via independent asynchronous firing of large numbers of motor units produces the grace and endurance of physiological motion. We have investigated the possibility of reproducing this physiological recruitment strategy by determining the selectivity of access to large numbers of ... | Funtional Neuromuscular Stimulation; Microelectrode Array; Neuroprosthesis; Intrafascicular Multielectrode Stimulation; Cats | 2004 |

Normann, Richard A.; Shoham, Shy | Encoding mechanisms for sensory neurons studied with a multielectrode array in the cat dorsal root ganglion | Recent advances in microelectrode array technology now permit a direct examination of the way populations of sensory neurons encode information about a limb's position in space. To address this issue, we recorded nerve impulses from about 100 single units simultaneously in the L6 and L7 dorsal root ... | Sensory; Encoding; Multielectrode; Dorsal Root Ganglion; Cutaneour; Muscle | 2004 |

Normann, Richard A. | Statistical encoding model for a primary motor cortical brain-computer interface | A number of studies of the motor system suggest that the majority of primary motor cortical neurons represent simple movement-related kinematic and dynamic quantities in their time-varying activity patterns. An example of such an encoding relationship is the cosine tuning of firing rate with respect... | Discrete Distribution; LN Model; Neural Decoding; Neuroprosthetics; Sequential Monte-Carlo Filter | 2005 |
