During inspiration, the expiratory neurons of the ventral respiratory group (VRG)are being inhibited.

Expiratory Neurons

Neurons involved in the control of the muscles responsible for expelling air from the lungs.

Ventral Respiratory Group

A cluster of neurons in the medulla oblongata that plays a critical role in controlling breathing.

Inspiration

Inspiration refers to the process of taking air into the lungs, a vital component of respiration, driven by muscle contraction and negative pressure inside the chest.
