A scientifically accurate model of the limbic system of the human brain, based on MRI scan data of a male.
The limbic system (or paleomammalian brain) is a complex set of brain structures located on both sides of the thalamus, right under the cerebrum. It is not a separate system but a collection of structures from the telencephalon, diencephalon, and mesencephalon. It includes the olfactory bulbs, hippocampus, amygdala, anterior thalamic nuclei, fornix, columns of fornix, mammillary body, septum pellucidum, habenular commissure, cingulate gyrus, parahippocampal gyrus, limbic cortex, and limbic midbrain areas.
The limbic system supports a variety of functions including adrenaline flow, emotion, behavior, motivation, long-term memory, and olfaction. Emotional life is largely housed in the limbic system, and it has a great deal to do with the formation of memories.
This model includes the following structures:
fornix, thalamus, pineal gland, cingulate gyrus,corpus callous, hippocampus, amygdala, maxillary bodies, parahippocampal gyri, and the hypothalamus.
They are color coded:fornix: dark purple
pineal gland: red
cingulate gyrus: fuscia
corpus callous: yellow
amygdala: dark blue
maxillary bodies: green
parahippocampal gyri: grey
