Fig. 4From: A Simple Algorithm for Averaging Spike TrainsA cartoon representation of the space of functions. Here, the large rectangle represents the space of functions, with S, the image of the space of spike trains in the space of functions under the filter map represented by the wavy line. The spike train functions are marked by open circles, the function average by a closed circle, and the central spike train function, which is the point on S closest to the function average, is marked as a starBack to article page
