Figure 7

Representative images showing retrograde labelling in the forebrain following injection of a retrograde tracer (Fluorogold) into barrel cortex. (a) Injection site in S1BF (barrel cortex). (b) Retrogradely labelled cells were not found in the piriform cortex (PC). Retrogradely labelled neurons are found primarily in layers 2,3 and 5 in the contralateral barrel cortex (c), ipsilateral ventral posteromedial (VPM) thalamus (d), adjacent ipsilateral S2 (somatosensory) cortex (e). There is also sparse labelling of neurons ipsilaterally in basal forebrain (BF) nuclei (f). IC, internal capsule; LH, lateral hypothalamus; VPL, ventral posterolateral thalamus; VL, ventral lateral thalamus. Scale bars, (a), 400 μm. (b–f), 100 μm. Images a–c and d–f are from different mice.
