third ventricle
Midbrain cerebrospinal space
The third ventricle is a narrow, fluid-filled cavity in the center of the brain, positioned between the two halves of the thalamus.
It connects to the lateral ventricles above and the fourth ventricle below, allowing cerebrospinal fluid to circulate through the brain's ventricular system.
