Paleoneurobiology is the study of brain evolution by analysis of brain endocasts to determine endocranial traits and volumes. Considered a subdivision of neuroscience, paleoneurobiology combines techniques from other fields of study including paleontology and archaeology. It reveals specific insight concerning human evolution.
An endocast is the internal cast of a hollow object, often referring to the cranial vault in the study of brain development in humans and other organisms. [1] Endocasts can be artificially made for examining the properties of a hollow, inaccessible space, or they may occur naturally through fossilization .
Analyzing variability in the location of gross anatomical landmarks such as sulci is an accepted method for studying evolutionary hominin brain reorganization. The position of the lunate sulcus in the occipital lobe has been studied in humans, early hominin endocasts, apes, and monkeys by researchers seeking to make inferences about the morphological evolution of brain regions associated with ...
The neocortex area of the brain, responsible for sensory perception and other sensory brain functions, covers 28% of the medium-sized A. commune endocast's surface area. [64] Another endocast, which belongs to Anoplotherium sp., measures 7,173.92 mm (282.438 in) 2 in the cerebrum surface, 4,419.56 mm (173.998 in) 2 in neopallium surface, and ...
Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species.
Braincase and virtual endocast The holotype skeleton of Gnathovorax is so well preserved that its describers were able to reconstruct a digital endocast of the brain. It possessed a large floccular fossa lobe (FFL) of the cerebellum , a portion of the brain generally (but not universally) considered useful for motor control of the eye, head ...
Brain endocast of an Iguanodon, created in 1897 from specimen NHMUK R2501. The neurobiology of ankylopollexians has been studied as far back as 1871, when a well preserved cranium (specimen NHMUK R2501 [14]) discovered in September 1869 from the Wealden Group on the Isle of Wight and tentatively referred to the genus Iguanodon was described by ...
Trilophosuchus brain regions. Like in other crocodylomorphs, the cranial endocast does not accurately reflect the shape of the brain itself and is instead also influenced by the extensive dural envelope. The endocast regardless gives a general idea of the brain shape, which is congruent with the linear and elongated endocasts of other ...
