Abstract: How does attentional modulation of a neuron's preferred feature, or changing its tuning width, or its response gain benefit behavioral performance? We investigate this in the context of a visual search task, e.g., search for a vertical bar among horizontal bars (which becomes more difficult as the target orientation approaches horizontal).
