WebAutoradiographic analysis shows that the μ-opioid receptor density was decreased in the striatum, thalamus and amygdala but not in the midbrain, nucleus accumbens, hippocampus or cortex in morphine offspring. In ventrolateral PAG neurons, morphine activated inwardly rectifying K + channels in 59% of recorded neurons of morphine offspring. WebMorphologically distinct chemosensory cells had long, thin dendritic endings and showed a stereotypic inwardly rectifying current elicited by prey extract (chemoreceptors, Figures 1 B–1D and S1 D). In contrast to mechanoreceptors, these cells were insensitive to mechanical stimulation ( Figures 1 B and 1D).
