Septum pellucidum

The septum pellucidum ( Latin : translucent partition) is an anatomical structure within the brain consisting of glial cells . It lies in the middle of the brain between the two halves of the brain, below the bar and is stretched like a membrane between the bar and fornix . The septum pellucidum forms part of the medial wall of the anterior horn of the lateral ventricles and structurally belongs to the limbic system .

The anatomical cavity between the left and right leaves of the septum pellucidum is called the cavum septi pellucidi .

An absence of the septum can be isolated as a harmless normal variant , combined with a bar deficiency ( agenesis of the corpus callosum ), or in combination with other alterations, in particular the optic nerve system may occur in a septo-optic dysplasia .
