In human anatomy, the
neurocranium, also known as the braincase, brainpan, or brain-pan  is the upper and back part of the  skull, which forms a protective case around the brain. In the human skull, the neurocranium includes the  calvaria or skullcap. The remainder of the skull is the facial skeleton.
comparative anatomy, neurocranium is sometimes used synonymously with endocranium or chondrocranium. 
The neurocranium is divided into two portions:
In humans, the neurocranium is usually considered to include the following eight bones:
ossicles (three on each side) are usually not included as bones of the neurocranium. There may variably also be extra  sutural bones present.
Below the neurocranium is a complex of openings (
foramina) and bones, including the foramen magnum which houses the neural spine. The auditory bullae, located in the same region, aid in hearing. 
The size of the neurocranium is variable among mammals. The roof may contain ridges such as the
The neurocranium arises from
paraxial mesoderm. There is also some contribution of ectomesenchyme. In Chondrichthyes and other cartilaginous vertebrates this portion of the cranium does not ossify; it is not replaced via endochondral ossification.
The neurocranium is formed by the
endocranium, the lower portions of the cranial vault, and the skull roof. These are not fused in fishes, and a proper neurocranium is only found in land vertebrates.
Evolutionarily, the human neurocranium has expanded from comprising the back part of the mammalian skull to being also the upper part: during the evolutionary expansion of the brain, the neurocranium has overgrown the splanchnocranium. The upper-frontmost part of the cranium also houses the evolutionarily newest part of the human brain, the frontal lobes.
