BigBrain is a freely accessible high-resolution 3D digital atlas of the human brain, released in June 2013 by a team of researchers at the Montreal Neurological Institute and the German Forschungszentrum Jülich and is part of the European Human Brain Project. [1] The isotropic 3D spatial resolution of the BigBrain atlas is 20 μm, much finer ...
In the field of computational neuroscience, brain simulation is the concept of creating a functioning computer model of a brain or part of a brain. [1] Brain simulation projects intend to contribute to a complete understanding of the brain, and eventually also assist the process of treating and diagnosing brain diseases .
The following depth map of a shark with smooth gradient produces a perfectly readable autostereogram, even though the 2D image contains small monotonic areas; the brain is able to recognize these small gaps and fill in the blanks (illusory contours). While intelligible, repeated patterns are used instead of random dots, this type of ...
[4] [5] [6] Public and community submissions to DEFCAD rose quickly, [7] and in March 2013, at the SXSW Interactive festival, DEFCAD was announced as a repurposed and expanded site that would serve as a 3D search engine and development hub. [8] [9] [10] DEFCAD has been called "The Pirate Bay of 3D Printing" [11] and "the anti-Makerbot". [10]
Model of a neural circuit in the cerebellum, as proposed by James S. Albus. Information from the sense organs is collected in the brain. There it is used to determine what actions the organism is to take. The brain processes the raw data to extract information about the structure of the environment. Next it combines the processed information ...
In some species, including fish and birds, the optic tectum, also known as the optic lobe, is one of the largest components of the brain. In hagfish, lamprey, and shark it is a relatively small structure, but in teleost fish it is greatly expanded, in some cases becoming the largest structure in the brain. In amphibians, reptiles, and ...
Preterm hypoxic injury remain difficult to study because of limited availability of human fetal brain tissues and inadequate animal models to study human corticogenesis. Cerebral organoid can be used to model prenatal pathophysiology and to compare the susceptibility of the different neural cell types to hypoxia during corticogenesis.
The brain-to-body mass ratio was however found to be an excellent predictor of variation in problem solving abilities among carnivoran mammals. [20] In humans, the brain to body weight ratio can vary greatly from person to person; it would be much higher in an underweight person than an overweight person, and higher in infants than adults.
