The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
The cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci. In the human brain, it is between 2 and 3-4 mm. thick, [8] and makes up 40% of the brain's mass. [2] 90% of the cerebral cortex is the six-layered neocortex whilst the other 10% made up of three ...
Ancient DNA. Cross-linked DNA extracted from the 4,000-year-old liver of the ancient Egyptian priest Nekht-Ankh. Ancient DNA (aDNA) is DNA isolated from ancient sources (typically specimens, but also environmental DNA). [1][2] Due to degradation processes (including cross-linking, deamination and fragmentation) [3] ancient DNA is more degraded ...
Bone fragments unearthed in a cave in central Germany show that our species ventured into Europe's cold higher latitudes more than 45,000 years ago - much earlier than previously known - in a ...
History of neuroscience. From the ancient Egyptian mummifications to 18th-century scientific research on "globules" and neurons, there is evidence of neuroscience practice throughout the early periods of history. The early civilizations lacked adequate means to obtain knowledge about the human brain. Their assumptions about the inner workings ...
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction. Being the most specialized organ, it is responsible for receiving ...
The skull was found in 1952 on the surface of an erosion gully, [1] a dry channel bed of the Vlekpoort River, near Hofmeyr, [2][3] a small town in Eastern Cape, South Africa. No other bones or archaeological artifacts were found in the vicinity at the time of the skull's discovery. [2] The skull is one of only a few African specimens of early ...
Orange: Temporal bone (2) Green: Occipital bone (1) Red: Ethmoid bone (1) In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan, [ 1 ][ 2 ] is the upper and back part of the skull, which forms a protective case around the brain. [ 3 ] In the human skull, the neurocranium includes the calvaria or skullcap.
