Several phenomena are currently under study.
Ionotropic histamine receptors and H2-receptors modulate supraoptic oxytocin neuronal excitability and dye coupling. Journal of Comparative Neurology, in press. G.I. Immunocytochemical basis for meningeo-glial networks. Histamine suppresses non-NMDA excitatory synaptic currents in rat supraoptic nucleus neurons. Nitric oxide via cGMP-dependent mechanisms increases dye coupling and excitability of rat supraoptic nucleus neurons.
