Limbic System Anatomy

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 is a complex system that consists mainly of the limbic lobe cortical areas and subcortical nuclei that have connections to the limbic lobe.

The former comprises of the neocortex orbital frontal cortex hippocampus insular cortex and the cingulate subcallosal and parahippocampal gyri.

Limbic system anatomy. Limbic system structures are involved in many of our emotions and motivations particularly those that are related to survival such as fear and anger. The latter on the other hand includes the amygdala olfactory bulb septal nuclei hypothalamus and the anterior and dorsomedial nuclei of the thalamus. The limbic system is a set of brain structures located on top of the brainstem and buried under the cortex.

The limbic system also known as the paleomammalian cortex is a set of brain structures located on both sides of the thalamus immediately beneath the medial temporal lobe of the cerebrum primarily in the midbrain. Functions of the limbic system the limbic system is involved with many of the expressions that make us human namely emotions behavior and states of feeling associated with memory especially the hippocampus. The limbic system consists of a number of structures including the fornix hippocampus cingulate gyrus amygdala the parahippocampal gyrus and parts of the thalamus.

Dr tim luijkx and dr azza elgendy et al. The limbic system sits atop the brain stem which is believed to be one of the first parts of the brain to develop react to stimuli and the most basic in terms of sustaining life. Associated with pleasure and rage the limbic system.

It supports a variety of functions including emotion behavior motivation long term memory and olfaction. The limbic system also involves connections with the midbrain and olfactory system. 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.

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. The hippocampus is one of the first areas affected by alzheimers disease. Its located on both sides of the thalamus and underneath the cerebrum.

As the disease progresses damage extends throughout the lobes.
