Canonical Response Parameterization: Quantifying the structure of responses to single-pulse intracranial electrical brain stimulation
Fig 4
Parameterizing the evoked response for single trials.
A. An example evoked response, as in Figs 2B and 3B. B. The voltage response Vk(t) from trial k (black) is parameterized by how strongly the canonical response shape (C(t), red trace, time interval t1 to τR) is represented (scaling factor αk) plus the “residual” εk(t) (green): Vk(t) = αkC(t) + εk(t). C. Overlaid Vk(t), αkC(t), and εk(t) for example trial #6. D. As in (C), for all 10 trials.
