本文介绍了一种新的动物模型，用于研究电刺激去大脑、麻痹和人工通气猫中脑导水管周围灰质（PAG）诱发的虚拟发声。诱发麻痹后PAG刺激诱发的膈神经、腹神经、返神经和上级喉神经的活动变化与麻痹前诱发的实际发声期间这些神经或由它们支配的肌肉的活动进行比较。PAG诱发的麻痹猫的呼吸和喉运动模式与PAG诱发的发声模式相似。此外，在两种模式中，从吸气到发声样活动的转换通常与肺充气同步。结论：刺激麻痹猫的PAG可诱发假声。
A new animal model is described for the study of fictive vocalization, evoked by electrical stimulation of the periaqueductal grey (PAG) in decerebrate, paralyzed and artificially ventilated cats. Changes in activities of the phrenic, abdominal, recurrent and superior laryngeal nerves induced by PAG stimulation after induction of paralysis were compared with the activities of these nerves or the muscles innervated by them during actual vocalization induced before paralysis. The PAG-induced respiratory and laryngeal motor pattern in paralyzed cats is similar to that of PAG-induced vocalization. Furthermore, the switch from inspiration to vocal-like activity is usually synchronized with lung inflation in both paradigms. It is concluded that fictive vocalization can be induced by PAG stimulation in paralyzed cats.
