Figure 3. Responses of example TE neurons.

(A) TE neuron tuned for large limb distance in category II. Each stimulus used to study this neuron is represented by a white icon. Background color indicates the time-averaged response rate to the stimulus (see scale bar) based on five repetitions including presentation as both object 1 and object 2. Stimuli are grouped into categories and arranged from lowest reward value (upper left) to highest (lower right). The shape cue indicating reward value is diagrammed beside each category. This neuron’s tuning provided potentially useful information about low reward values in category II. (B) TE neuron tuned for broad curvature in category IV. This tuning provided potentially useful information about high reward values in category IV. See also Figures S2 and S4.
