A general diagram illustrating the overall processing pipeline is included in Fig. But if you're comparing brain size relative to body size, as the breed's body size gets smaller, dog brain size doesn't necessarily shrink in exact proportion. Veterinarians do, however, commonly diagnose congenital hydrocephalus with other malformations such as: An abnormality of the skull and vertebra at the base of the skull creating inadequate space for the brain to function.

The behavioral specialization associated with the most components (four of six) was explicit companionship, and the component associated with the most behavioral specializations (six of 10) was component 4, which involves regions involved in social action and interaction.
