The Nervous System in Pedro Ortiz Cabanillas’s Sociobiological Informational Theory: An Epistemological Alternative to Classical Neuroanatomy
Human Arenas May 17, 2026 Hans Contreras-Pulache, Diego Carrera-Hidalgo, Ana Astorga-Cota et al.
Pedro Ortiz Cabanillas's model of nervous system organization integrates emotional, productive, and volitional components across five hierarchical levels—cellular, tissue, neural, paleocortical, and neocortical—spanning biological, psychological, symbolic, and social dimensions. Developed in Peru under challenging conditions, his sociobiological informational theory presents the nervous system as a dynamic, integrative unit where biological and psychosocial processes converge. This framework offers a counterpoint to mainstream neuroscience and enriches epistemological perspectives on human complexity.
