Figure 1From: The effect of adolescent testosterone on hippocampal BDNF and TrkB mRNA expression: relationship with cell proliferation Representative autoradiographs of TrkB mRNA in situ hybridisation in coronal sections of the rhesus macaque hippocampus. (A-B) TrkB-TK+ mRNA was particularly highly expressed in the dentate gyrus, CA2 and the middle layers of the parahippocampal cortex (white arrow). (C-D) TrkB-TK- mRNA was highly expressed in the dentate gyrus and moderately expressed in the hilus and entorhinal cortex, but was much lighter in the CA1 region. TrkB-TK- mRNA was more highly expressed in the superficial white matter (black arrow). dg = dentate gyrus.Back to article page
