Cortical white matter increases from childhood (~9 years) to adolescence (~14 years), most notably in the frontal and parietal cortices. [8] Cortical grey matter development peaks at ~12 years of age in the frontal and parietal cortices, and 14–16 years in the temporal lobes (with the superior temporal cortex being last to mature), peaking at about roughly the same age in both sexes ...
[7] Before the evolutionary development of the brain, nerve nets, the simplest form of a nervous system developed. These nerve nets were a sort of precursor for the more evolutionarily advanced brains. They were first observed in Cnidaria and consist of a number of neurons spread apart that allow the organism to respond to physical contact ...
Bipedal tool-using primates from the subtribe Hominina date back to as far as about 5 to 7 million years ago, such as one of the earliest species, Sahelanthropus tchadensis. From about 5 million years ago, the hominin brain began to develop rapidly in both size and differentiation of function.
Islamic medicine in the middle ages was focused on how the mind and body interacted and emphasized a need to understand mental health. Circa 1000, Al-Zahrawi, living in Islamic Iberia, evaluated neurological patients and performed surgical treatments of head injuries, skull fractures, spinal injuries, hydrocephalus, subdural effusions and headache.

These are timelines of brain development events in different animal species. Mouse brain development timeline; Macaque brain development timeline;
All bilateria are thought to have descended from a common wormlike ancestor that appeared in the Cryogenian period, 700–650 million years ago. [18] The fundamental bilaterian body form is a tube with a hollow gut cavity running from mouth to anus, and a nerve cord with an especially large ganglion at the front, called the "brain".
ROCKFORD, Ill. (WTVO) – The American Academy of Pediatrics has updated its literacy promotion policy for the first time in 10 years. The update is based on research that shows that it’s never ...
Brain mapping can show how an animal's brain changes throughout its lifetime. As of 2021, scientists mapped and compared the whole brains of eight C. elegans worms across their development on the neuronal level [68] [69] and the complete wiring of a single mammalian muscle from birth to adulthood.
