Estimated dynamics of firing across all trials of a transitive inference task.

<div> <div> <div> <p>A rhesus macaque was presented with the 21 possible pairs of stimuli from a 7-item list. The subject was unfamiliar with the stimuli at the outset, and learned the ordered list by trial and error over the course of the session. Left. Raster of spikes from a parietal neuron during completed trials. Right. ARRIS estimate of firing, interpolated across all trials. </p> </div> </div>
