We measured binding using 125I αBGTX, (selective for α7 nAChRs) and 3H‐Epi (selective for heteromeric nAChRs in the presence of an excess of unlabelled αBGTX) in temporal cortices obtained from 14 patients with deep temporal high‐grade tumour and 14 with TLE (Fig. 1A and B). This evidence concerns the gene CHRNA7 and neoplasm.
