Responses of reticulospinal vasomotor neurons, recorded in the rostral ventrolateral reticular nucleus of the medulla oblongata, to γ-aminobutyric acid (GABA) and cyanide microiontophoreses were examined during H+iontophoresis in anesthetized rats. Extracellular H+iontophoresis attenuated GABA-evoked decreases and enhanced cyanide-induced increases in the neuronal activity, but had no effect on the neuronal activity when applied alone. Opposite responses were produced during OH−iontophoresis. Similar effects were also observed on the glycine-evoked inhibition of these neurons during H+and OH−iontophoreses, suggesting that H+modulation of the GABA-evoked inhibition may not result from a specific action at the GABA receptor-channel complex. It is concluded that extracellular H+ions exert a modulatory action on responses of the reticulospinal vasomotor neurons to other neuro-active substances and may significantly contribute to hypoxic-ischemic cardiovascular regulation.
