In this review we summarize the current knowledge on the structural and functional alterations occurring in astrocytes from the human brain in pathological conditions such as epilepsy, primary tumours, Alzheimer’s disease, major depressive disorder and Down syndrome. Compelling evidence thus shows that ...
Human evolution - Brain Size, Adaptations, Fossils: Because more complete fossil heads than hands are available, it is easier to model increased brain size in parallel with the rich record of artifacts from the Paleolithic Period (c. 3.3 million to 10,00
brain develops more rapidly than do other organs. The seventh month is generally regarded as the earliest age at which anewborncan survive without medical assistance. The newborn infant By definition,infancyis the period of life between birth and theacquisitionof language approximately one to two ...
The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than the brains of many...
New variants of two brain-development genes have swept through the human population during the last several thousand years, biologists reveal
Epistemic status: grain of salt (but you can play around with the model yourself). There's lots of uncertainty in how many FLOP/s the brain can perform. In informal debate, I've regularly heard people say something like,"oh but brains are so much more efficient than computers"...
2c). No differences were found between independent control and C9 ALI-COs in the reconstructed path recapitulating the milestones of human brain development (Fig. 2c and Extended Data Fig. 2d). To confirm this finding, we projected transcriptomic data obtained from the organoid cell populations...
The human brain is constantly being shaped by new information throughout your life, so when you see ads for vitamins that feature women with thin waists as an "ideal" of fitness your brain is quick to pick up on that and along. These kinds of images can change how we perceive beauty ...
