Depolarization of a single RVLM neuron from rats carrying the chromosome 1 QTL (quantitative trait locus) of SHRSP (WKYpch1.0 and SHRSP) in response to superfusion with Ang II (6 μmol l−1) was significantly larger than that from rats without the QTL (cited from Iigaya et al.56). (a) Representative traces from each strain. (b) Changes in membrane potential (depolarization) of the RVLM neurons in response to Ang II superfusion (the mean±s.d. of eight neurons from different rats of each strain).
