Figure 4.
Example of synaptic input maps from matched layer 5 and layer 6 corticocollicular neurons. A, Excitatory synaptic input map from a layer 5 corticocollicular neuron. B, Inhibitory synaptic input map from a layer 5 corticocollicular neuron. Excitatory (C) and inhibitory (D) synaptic input maps from a layer 6 corticocollicular neuron taken from just below the layer 5 neuron in A and B. In all cases, traces from individual stimulation sites shown in a–c, which correspond to locations denoted on the adjacent heat maps. Colorbars indicate F statistic.
