Figure 1.

Visual stimuli used to measure size tuning curves. A, Presentation of a series of randomly interleaved dots stimuli of varying stimulus RMS contrast and size. The dots always moved in the preferred direction and speed of the neuron. Contrast stimuli were fully coherent. B, Presentation of a series of randomly interleaved dots stimuli of varying motion coherence and size. The coherent dots moved in the preferred direction and speed of the neuron while the remaining dots were replotted randomly. Coherence stimuli were presented at maximum contrast. All stimulus sizes and coherences were randomly interleaved.
