Interesting study showing positive and negative control of autonomic breathing by allopregnanolone and DHEA-S
The principal finding of this study was that the efficacy of GABAA receptor-mediated modulation of respiratory membrane potential and rhythmogenesis is markedly enhanced by allopregnanolone and depressed by dehydroepiandrosterone sulphate. These data demonstrate that the modulation of breathing via GABAA receptor activation will be determined by the overall balance of negative and positive neurosteroid modulators within respiratory nuclei
