Periaqueductal gray (PAG) and nucleus tractus solitarius (NTS) are important centres for regulation of cardiorespiratory function in cats. We aimed to study the effects of specific PAG stimulation on cardiorespiratory parameters in the rat. Microinjection of D, L-homocysteic acid (DLH) into dorsolateral PAG of anaesthetised rats, led to: marked increases in(More)
Domperidone, a dopamine D(2) receptor antagonist, is a tool for uncovering the tonic and dynamic effects of the peripheral dopaminergic system in unanesthestized animals. The hypothesis was that domperidone effects would vary between strains of the same species. Ventilatory behavior -- frequency and minute ventilation -- was measured by the plethysmographic(More)
