This is the first study to compare the influence of nasal afferent stimulation on inspiratory and expiratory muscle activity during sneezing, in kittens and adult cats. In kittens, we demonstrate that nasal afferent stimulation does not reinforce inspiratory activity prior to the expiratory thrust as it normally does in adult cats. These stimulations evoke an active expiration similar to but weaker than the expiratory thrusts observed under the same conditions during sneezing in adult cats. Sneezing can be elicited from three weeks of life. Among the different hypotheses discussed, the most likely explanation appears to be the immaturity of medullary respiratory connections.
这是第一项比较鼻腔传入刺激对小猫和成年猫打喷嚏时吸气和呼气肌肉活动影响的研究。在小猫中，我们证明鼻腔传入刺激不会像在成年猫中那样在呼气推力之前增强吸气活动。这些刺激引发的主动呼气与成年猫在相同条件下打喷嚏时观察到的呼气推力相似，但较弱。从出生三周起就能引发打喷嚏。在讨论的不同假设中，最有可能的解释似乎是延髓呼吸连接不成熟。
