title: New studies of cranial growth.
abstract: Additional experimental data indicate that cranial base elongation is secondarily responsive to prior alterations of the neural mass, further supporting the functional matrix concept. Additional studies of epithelial growth and of muscle regeneration suggest that neurotrophic processes, regulating functional matrices, may play a significant role in both normal and abnormal cephalogenesis.
