Fig. 6.

Proximity of labeled corticothalamic projections with respect to thalamocortical neurons labeled by the other tracer. A. Reconstruction of labeled corticothalamic terminals in the contralateral thalamus shown with respect to retrogradely-labeled soma in case BN11. Only contralaterally-labeled corticothalamic projections are shown, the locations of the ipsilaterally-labeled corticothalamic projections have been removed. Scale, 1 mm. B. Overlap analysis of FR-labeled terminals and AF-labeled neurons after subdividing the left half of the thalamic reconstruction into an array of 100 μm² bins. Green bins contain AF-labeled neurons, red bins contain AF-labeled terminals, white bins contain both neurons and terminals. Percentage indicates the proportion of labeled bins that are white. C. Overlap analysis of AF-labeled terminals and FR-labeled neurons in the right half of the same thalamic section shown in panel A. A copy of the figure using magenta-green coloring is available as a supplementary figure.
