Respiratory-related neurons of the fastigial nucleus in response to chemical and mechanical challenges

Anesthetized, paralyzed, and ventilated cats

Respiratory challenges including: 1) cessation of the ventilator for a single breath at the end of inspiration or at functional residual capacity, 2) cessation of the ventilator for multiple breaths, and 3) exposure to hypercapnia

Control conditions (spontaneous activity)
