Coupled inhibition at blink reflex dominant in rabbits

  • 10 Accesses

Conclusions

  1. 1.

    When the interval between ocular stimulation with an air stream and the delivery of water to the rabbit's oral cavity is 100 msec, a regular inhibition of the swallowing reflex is observed.

  2. 2.

    When a focus of excitation lacking the properties of a dominant focus is created in the blink center, the inhibition of the swallowing reflex is demonstrated at intervals of 2–4 sec between the series of ocular stimulation and water delivery.

  3. 3.

    At the onset of formation of the dominant focus, when the dominant undergoes the summation-reflex stage, the swallowing reflex is not inhibited. Upon the transition of the dominant to the optimum stage, i.e., the reinforcement of a distinct modality by stimuli, a regular coupled inhibition of the swallowing reflex was demonstrated.

  4. 4.

    During investigation of the influence of the blink center on the swallowing center, it was found that after the establishment of the temporal connection a circulatory interaction between centers occurs according to the summation-reflex type.
