Ventricles of brain. Coloured composite 3-D magnetic resonance imaging (MRI) scan of a human brain seen from the side, showing the ventricles (orange). The front of the brain is at left. These cavities circulate cushioning cerebrospinal fluid (CSF). The two large lateral ventricles lie either side of the mid-line of the brain, one in each cerebral hemisphere. They communicate with the third ventricle (not seen), which lies between and just below them. This leads down to the fourth ventricle (lower right) via a narrow channel, the cerebral aqueduct. Beneath the lateral ventricles lie the thalami (green), the brain's sensory-processing centres.
