Automatisation of a localising technique in aphasia based upon averaged evoked potentials

International Journal of Bio-medical Computing
C Liedtke, G K Morley


Averaged evoked potentials were utilised as a localising technique in aphasia. Based on a set of measurements extracted from various evoked potentials, subjects from four diagnostic categories were correctly classified in more than 70% of the cases. The measurements were derived from amplitudes and latencies of significant peaks which were selected by human judgement from plots of the recorded evoked potentials. An algorithm has been developed which simulates the manual procedure and reduces the processing time per patient by several magnitudes. The automated method yields results which are more consistent with expected results than those from the manual method. The percentage of correct classification is in both cases essentially the same.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
