Discharge properties of dorsal medullary inspiratory neurons in newborn pigs.
The discharges of medullary inspiratory neurons were recorded in newborn pigs. They were classified by discharge pattern; response to lung inflation; synaptic relation to phrenic motoneurons. Our results showed: these neurons have similar discharge patterns and responses to lung inflation as adult cats; most neurons do not project to phrenic motoneurons. It is suggested that our sampled population of neurons is involved in integrating pulmonary afferent inputs.
