160 Normann, Richard A.Statistical encoding model for a primary motor cortical brain-computer interfaceA 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 Filter2005
161 Larson, Scott A.Strabismus surgery complications: prevention and managementStrabismus surgery is increasingly becoming a subspecialty domain, especially with cyclovertical muscles, restricted muscles, or reoperations.
