Glycinergic Interneurons in the Respiratory Network of the Rhythmic Slice Preparation

The neuronal network in the pre-Botzinger Complex is the key element of respiratory rhythm generation. Isolated in a slice preparation, the pre-Botzinger Complex network is still able to generate its inspiratory activity. Although the mechanism of rhythm generation in principle relies on glutamatergic neurons, interestingly we found that glycinergic neurons represent a major portion of all inspiratory neurons in the slice preparation.
