Figure 3From: Cortical control of hering-breuer reflexes in anesthetized rats Alterations in Hering-Breuer reflexes in response to cortical stimulation. A - expiratory-promoting reflex; B - inspiratory-inhibitory reflex. TE (%) - duration of the first expiration after inspiratory occlusion expressed as a percent of the TE of the last pre-occluded breath; TI (%) - duration of the first inspiration after expiratory occlusion expressed as a percent of the TI of the last pre-occluded breath. *P < 0.05.Back to article page
