Rhythm controllers in the brainstem


1. Medulla

     Dorsal respiratory group – associated with inspiration

       Ventral respiratory group – associated with expiration.

          Pre-Botzinger Complex -  pattern generator, also ventral

 2)   Pons

   Apneustic center – has an excitatory   function

            Pneumotaxic center – can inhibit inspiration


Other regions of the brain that can affect respiration


1. Cortex

       Can exercise voluntary control

2)   Limbic system and hypothalamus

     Emotional states
