Central pattern generators also contribute to locomotion in humans. In 1994, Calancie, et al. described the "first well-defined example of a central rhythm generator for stepping in the adult human." The subject was a 37-year-old male who suffered an injury to the cervical spinal cord 17 years prior.
The central pattern generators responsible for locomotion in vertebrates reside as half-center modules in the cervical and lumbar region of the spinal cord. Each CPG generates a basic motor output pattern that is responsible for the rhythmic contractions of flexor-extensor muscles that correspond to the forelimbs and hindlimbs. [3]
Biologically realistic alternatives to the metaphor of the "motor program" are represented by central pattern generators. [1] p. 182 Signals transmitted through efferent and afferent pathways allow the central nervous system to anticipate, plan or guide movement.
A central pattern generator (CPG) is defined as a neural network that does not require sensory input to generate a rhythm. This rhythm can be used to regulate essential physiological processes. These networks are often found in the spinal cord.
Central pattern generators are neuronal circuits that—when activated—can produce rhythmic motor patterns in the absence of sensory or descending inputs that carry specific timing information. Examples are walking , breathing , and swimming , [ 75 ] Most evidence for central pattern generators comes from lower animals, such as the lamprey ...

The pneumotaxic center controls both the rate and the pattern of breathing. The pneumotaxic center is considered an antagonist to the apneustic center (which produces abnormal breathing during inhalation), cyclically inhibiting inhalation. The pneumotaxic center is responsible for limiting inspiration, providing an inspiratory off-switch (IOS ...
