What are the brain ventricles and what is their role? Read on to learn more about these structures and which health conditions they relate to. Overview The Ventricles of the Brain are a connecting network of cavities inside the brain parenchyma that are filled with cerebrospinal fluid (CSF). The ventricular system is made up of two lateral ventricles , a third ventricle , the cerebral aqueduct, and a fourth ventricle (as shown in the figures below). The choroid plexuses in the ventricles produce CSF, which fills the ventricles and subarachnoid space after a continual cycle of production and reabsorption. Structure And Function The ... The ventricular system is a set of four interconnected cavities in the brain that produce and circulate cerebrospinal fluid (CSF). Learn about the structure, development, and function of the ventricles and their relation to the neural tube and the spinal cord. The ventricular system of the brain is an interconnected series of cavities filled with cerebrospinal fluid (CSF) that cushions the brain . Though the presence of cerebral ventricles was known since ancient times, its function was obscure. Early scientists believed ventricles to be the site of thought, emotions, reasoning, and memory. Leonardo da Vinci, the famed artist who drew Mona Lisa, performed the first ventriculography on the brain of an ox. However, in the 17th century, it was ...
