What is the cranial capacity?

Cranial capacity is a measure of the volume of the skull interior. This term is used for vertebrates who have a skull and brain. Cranial volume is often used as a general estimate for vertebrate brain size. Cranial capacity measurements cannot in itself identify injuries or abnormalities in the brain if these injuries do not cause a significant brain swelling and extreme distortion of the skull by extending. One of the cases where this volume can be used to diagnose problems is if the hydrocephalus or fluid in the brain occurs, as the presence of fluid often causes the brain and the skull to significantly increase. The preferred media for this calculation are beads or small metal balls such as Buckshot. This method does not give accurate volume measurement, but if the individual pieces are used to fill the skull sufficiently small, it is possible to make a reasonably accurate estimate. Because adult human skulls must be very different, a small range of error is rarely significant.

The ongoing debate exists whether greater cranial capacity is associated with higher intelligence, but there is no definitive answer on this topic. This is not due to lack of research, but rather of lack of real consensus. In hominidic species and people, studies have been conducted that credibly claim that cranial capacity is an important indicator of intelligence, and other studies successfully claim that this is not the case. With such contradictory data, a solid conclusion cannot be achieved at present.

The most common contexts in which arguments about the advantages of cranial capacity need to be heard are related to the studies of various hominidal species and measurements of human IQ. Despite the absence of a clear consensus on the importance of this measurement, there are many renowned scientific studies that can validly maintain adequate aspects. All these studies have one point of agreement, which is that the skull volume does not directly affect the personality, temperament or predisposition to certain talents or behavior. Causal inAzby, such as these, have been refuted many times, because in addition to the size of the skull of someone are always other factors, especially the condition and plasticity of the brain itself.
