Figure 1. Projection of spike train onto likelihood space.

Sample response of a single neuron to face stimulus presentation in raster plot format. This data is for the repeated trials, where each row is the spike train recorded for any individual trial. The transformation of the spike train for the single trial, from the observation space into a likelihood space, is illustrated. Based on previous observations and estimated stimuli conditional probability distribution, each point in the new space is generated by the projection of the binary vector of spike train.
