Based on 4 specimens, the A. africanus brain volume averaged about 420–510 cc (26–31 cu in). Based on this, neonatal brain size was estimated to have been 165.5–190 cc (10.10–11.59 cu in) using trends seen in adult and neonate brain size in modern primates.
The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...

Australopithecus (/ ˌ ɒ s t r ə l ə ˈ p ɪ θ ɪ k ə s,-l oʊ-/, OS-trə-lə-PITH-i-kəs, -loh-; [1] or (/ ɒ s ˌ t r ə l ə p ɪ ˈ θ iː k ə s /, os-TRA-lə-pi-THEE-kəs [2] from Latin australis ' southern ' and Ancient Greek πίθηκος (pithekos) ' ape ' [3]) is a genus of early hominins that existed in Africa during the Pliocene and Early Pleistocene.
Researchers also discovered that for every additional sleep disruption, there was a 0.006 cm 3 brain volume increase in the hippocampus. “We think, in this specific case of sleep apnea, that ...
There were several reasons that it took decades for the field to accept Dart's claim that Australopithecus africanus was in the human line of descent. First and foremost was the fact that the British scientific establishment had been fooled by the hoax of the Piltdown Man, which had a large brain and ape-like teeth. [15]
