neurocranium

In mammals, the neurocranium or braincase is the back part of the skull and houses the brain. In front of it is the interorbital region. The size of the braincase is variable among mammals. The roof may contain ridges such as the temporal crests. Below the braincase is a complex of foramina (openings) and bones, including the foramen magnum which houses the neural spine. The auditory bullae, located in the same region, aid in hearing. In humans, it is the upper portion of the skull.
