We examined effects of hypocapnia on burst activity in the piriform-amygdala complex and C(4) inspiratory activity in limbic-brainstem-spinal cord preparations from 0- to 1-day-old rats. Hypocapnia (2% CO(2)) increased the burst rate in the piriform-amygdala complex but decreased the C(4) inspiratory burst rate. Since hyperventilation induces hypocapnia, and enhanced amygdala activity may be involved in induction of a sense of anxiety, our findings might explain the neuronal mechanism of a vicious circle between hyperventilation and an increased sense of anxiety.
