dc.description.abstractElectroencephalographic evoked responses can be divided in at least three classes; transient responses, steady-state responses, and broad-band responses. According to the classic view, the underlying neural mechanisms of evoked responses di˙er substantially. However, several recent studies have found evidence suggesting a common mechanism explaining steady-state responses by a superposition of a transient response. In this study, we investigated the superposition hypothesis in the visual domain. We estimated the transient response to a single flash using a generative linear framework. This was achieved by a deconvolution of broad-band responses. From this transient response, we generated synthetic steady-state and broad-band responses by summation of time-shifted versions of this transient response. We were able to obtain a portion of explained variance of 0.56, on average. We did not find appreciable oscillatory activity in the residuals. Therefore, steady-state and broad-band responses can be understood as linear phenomenon, in line with the superposition hypothesis.en_US
