The lower-lying structures of the brain are primarily involved in biological functioning necessary for survival and reproduction, while the cerebral cortex is responsible for more advanced activity, such as thought development and processing. It is based on the fact that the brain and its neural circuitry is plastic and self-regulating, especially in its own activation and inactivation.
