Encephalization: How Evolution Built Our Complex Minds
ENCEPHALIZATION: Definition and Core Principles The concept of encephalization defines the evolutionary process characterized by the transfer of sophisticated cognitive functions from phylogenetically older, more primitive brain areas to the expansive, highly developed cerebral centers, predominantly the neocortex. This phenomenon represents a fundamental mechanism driving the increase in complexity and flexibility of behavior across mammalian, […]
Paleocortex: Unlocking Our Ancient Brain
Introduction and Definition of the Paleocortex The paleocortex, translating literally to the “old cortex,” represents a phylogenetically ancient division of the cerebral cortex, distinguished fundamentally by its simplified cytoarchitecture compared to the expansive six-layered neocortex. It is formally classified as a type of allocortex, a term encompassing cortical regions that possess fewer than the standard […]
