     • The increase of brain size relative to body size—encephalization—is intimately linked with human evolution. However, two genetically different evolutionary lineages, Neanderthals and modern humans, have produced similarly large-brained human species.

   How does a human brain increase in size?

   • The authors propose that the increase in human brain size was facilitated by a combination of stabilization of energy inputs and a redirection of energy from locomotion, growth and reproduction. The human brain stands out among mammals by being unusually large.

   How did human evolution affect brain enlargement?

   • We propose that during human evolution improved diet quality, allomaternal subsidies, cognitive buffering, reduced locomotion costs and reduced allocation to production all operated simultaneously, thus enabling the extraordinary brain enlargement in our lineage.

   Can a human brain expand beyond its present size?

   • So any further expansion of the adult human brain beyond its present size may take place without a radical change in its fetal/neonatal developmental schedule.

   What happens if a brain size increases beyond 2800 cm 3?

   • A further increase in the size of the brain beyond that point, i.e., at 2800 cm 3, would increase the cortical surface area, but the “window” would decrease, leading to a lower degree of neuronal integration and an increase in response time.

   Feb 20, 2024 · The brain is an organ of soft nervous tissue that is protected within the skull of vertebrates. It functions as the coordinating center of sensation and intellectual and nervous activity. The brain consists of billions of neurons (nerve cells) that communicate through intricate networks.

   Mar 17, 2023 · The brain is an organ composed of nervous tissue that commands task-evoked responses, movement, senses, emotions, language, communication, thinking, and memory. The three main parts of the human brain are the cerebrum, cerebellum, and brainstem. See Image. Human Brain, Encephalon.
