Part of the ventricular system of the brain, forming a single large irregularly shaped cavity located on the midline of the rhombencephalon, between the medulla, pons and the isthmus ventrally and the cerebellum dorsally. It is continuous with the cerebral aqueduct anteriorally and the central canal of the spinal cord posteriorly. It communicates with the subarachnoid space through its lateral and median apertures.

Irregularly shaped cavity in the rhombencephalon, between the medulla oblongata, the pons, and the isthmus in front, and the cerebellum behind. It is continuous with the central canal of the cord below and with the cerebral aqueduct above, and through its lateral and median apertures it communicates with the subarachnoid space.[AAO]
The fourth ventricle is an irregularly shaped cavity in the rhombencephalon, between the medulla oblongata, the pons, and the isthmus in front, and the cerebellum behind. It is continuous with the central canal of the cord below and with the cerebral aqueduct above, and through its lateral and median apertures it communicates with the subarachnoid space[GO][GO:0021592].
Fluid-filled brain cavity. Kimmel et al, 1995.[TAO]
The early development of most vertebrate brains is similar (...). The zebrafish neural tube follows the same basic differentiation pattern as the mammalian neural tube (reference 1); The brain develops from three embryonic enlargements of the neural tube, which later differentiate into five regions. A forebrain differentiates into telencephalon and diencephalon. The midbrain, or mesencephalon, remains undivided. The hindbrain divides into the metencephalon and myelencephalon. Cavities within the brain enlarge to form a series of interconnected ventricles (reference 2).[well established][VHOG]
