Illustration of the Posterior Perforated Substance

The Posterior Perforated Substance is an anatomical structure found in the human brain. It is part of the Brainstem and is located in the Midbrain region, specifically at the base of this region.

Anatomy

The Posterior Perforated Substance is a small, irregularly shaped area that is perforated by numerous small blood vessels. It is located between the Crus Cerebri and the Corpora Quadrigemina, and is continuous with the Interpeduncular Fossa.

Function

The primary function of the Posterior Perforated Substance is to allow the passage of blood vessels into the brain. These blood vessels supply the Thalamus, Hypothalamus, and the Basal Ganglia with oxygen and nutrients.

Clinical Significance

Damage to the Posterior Perforated Substance can lead to a variety of neurological disorders. For example, it can cause Weber's Syndrome, a condition characterized by paralysis of the eye muscles and contralateral hemiplegia.
