Computer generation of templates for evaluating the amplitude and latency parameters of two superimposed constituent components of early somatosensory evoked responses.
From a study of the range of morphologies of the early somatosensory evoked response (SSER) to median nerve stimulation in a large number of neurosurgical patients, the earliest cortical SSER has been inferred to consist of two superimposed waveform complexes. A description is given of the process of generating templates in the computer so that the relative amplitudes and latencies of these two complexes can be determined by inspection. It is suggested that although the neural substrate of the two complexes is at present unknown, their evaluation in responses will provide additional information which will be useful when using SSERs as aids to the diagnosis of neurological disease.
