Phylogenetically, hippocampus represents the archicortex and is composed of the following 3 layers:The parahippocampal cortex (neocortex) is composed of 6 layers. 1994;163 (3): 657-65.3. Limbic System: Functions, Parts and Anatomy (with Images) He limbic system Is a part of the brain composed of several anatomically and functionally interconnected structures involved in the processing of emotions.

The limbic system functions to facilitate memory storage and retrieval, establish emotional states, and link the conscious, intellectual functions of the cerebral cortex with the unconscious, autonomic functions of the brain stem. The precentral gyrus (posteriormost gyrus of the frontal lobe) contains the primary motor cortex and controls the precise movements of skeletal muscles. Diencephalon & Choroid Plexus. The thalamusacts as a gatekeeper for messages passed between the spinal cord and the cerebral hemispheres.
Donate today. The limbic system is a complex system that consists mainly of the limbic lobe, cortical areas and subcortical nuclei that have connections to the limbic lobe. It traverses both hemispheres in a front to back direction, connecting many vitally important brain centres as if it were a basic mainline for the distribution of energy and information. Known as the limbic system, these structures come in pairs.
