Quantitive analysis of autoradiograms after in situhybridization for NSP and Oct-1 mRNA in the cortex, hippocampus, and cerebellum of thyroid hormone-manipulated adult rats. Values shown represent mean + SEM (n) of film density (converted to % controls ± CV) over the cortex, hippocampus, or cerebellum.
