ab: Summary: Neurons in visual cortex receive most inputs from other cortical
    neurons with similar stimulus preference. To understand the role of
    this arrangement in information transmission we use a computational
    model to quantify the information about external stimuli that a typical
    cortical neuron receives through its cortico-cortical synapses. We find
    that efficient readout of the information encoded by an afferent
    population with orientation tuning similar to that observed in area V1
    requires the spread of orientation preferences of excitatory cortical
    afferents to take a value in agreement with experiments. We suggest
    that the organization of V1 cortico-cortical synapses allows efficient
    information transmission.
