Degenerative chronic spinal cord compression induced cervical myelopathy is a common cause of spinal cord dysfunction. The disease generally leads to impairment of the sensory and motor function of the cord progressively and insidiously. However, the underlying pathophysiology and the precise mechanism of the disease are still uncertain and remain to be investigated. The establishment of an animal...
This paper undertakes a comparative study of adaptive signal enhancers (ASE) of somatosensory evoked potentials (SEP) for spinal cord compression detection. We compare the ASE methods based on two adaptive filtering algorithms: the least mean squares (LMS) and Kalman filter (KF) in terms of their convergence rate, variability, and complexity. In addition, the two ASE methods are compared with the...
This paper proposes to apply a high-resolution time-frequency analysis (TFA) algorithm, the matching pursuit (MP), to extract and identify detail components of somatosensory evoked potential (SEP) signals. Conventional TFA methods showed limited time-frequency resolution in short-period nonstationary SEP signals so that they cannot reveal detail components in time-frequency domain. The MP algorithm...
The control of neuron position and orienting axon outgrowth is a significant focus in the development of cell biosensors and the study of neural regeneration. During the development, neurons communicate with each other by growing out axons and dendrites to form network. For the central nerve system: brain and spinal cord, which are very limited in their ability to repair. A better resolution for the...
