Peripheral control of avian respiration


, : Peripheral control of avian respiration. Federation Proceedings 29(5): 1664-1673

Receptors in the lungs of chicken which responded rapidly and were sensitive to small changes in CO2 are described. Afferent impulses from these were conducted centrally via the vagus nerve and its three pulmonary branches, the anterior branch having most fibres from CO2 receptors. Receptors were dispersed within the lung, even in the airway leading to a specific air sac. Single unit vagal activity from the receptors was inversely related to CO2 content in the ventilating gas stream.

Our discovery of high degrees of circular polarisation in some star-forming regions provides an attractive mechanism for the origin of homochirality. The largest degrees of circular polarisation, so far observed at near-infrared wavelengths, are t...
