Kunstige neurale net er inspireret af biologisk neurale net som vi kender fra hjerner i alle dyr på jorden. I det abstraktionsniveau som er nyttigt her består et neutralt net af neuroner, axoner og dendritter.
Astrocytter "regerer" i vores hjerne?:
RIKEN. (2016, April 25). Change in the brain: Astrocytes finally getting the recognition they deserve. ScienceDaily: Citat: "... Until recently, synaptic strength was thought to change only at synapses of active presynaptic neurons. Now, RIKEN scientists have shown that the truth is more complicated, and more interesting. ... "We have found an active mechanism that helps to increase variation in synaptic strength," explains lead scientist Yukiko Goda, "and surprisingly, it comes from astrocytes, which have previously been thought to play mostly passive roles in the brain." ..."
September 27, 2012, scitechdaily.com: Study Suggests that Astrocytes are Critically Important for Processing Sensory Information: Citat: "... The findings, published this week in the online edition of the Proceedings of the National Academy of Sciences, are the latest in a growing body of evidence suggesting that astrocytes are critically important for processing sensory information, says Mriganka Sur, the Paul E. and Lilah Newton Professor of Neuroscience at MIT and senior author of the paper. [] Sur’s lab has been studying astrocytes for about five years, as part of a longstanding interest in revealing the functions of different cell types in the cortex. The star-shaped cells were first discovered and named 150 years ago, but since then, “it’s been a mystery what they do,” says Sur, who is a member of MIT’s Picower Institute for Learning and Memory and director of the Simons Center for the Social Brain at MIT. ... “If you are paying attention to something, which causes this release of acetylcholine, that leads to a long-lasting memory of that stimulus. If you remove the astrocytes, that doesn’t happen,” Sur says. ..."
October 10, 2014, scitechdaily.com: Previously Unknown Mechanism Repairs Brain after Stroke: Citat: "... The researchers have shown that following an induced stroke in mice, support cells, so-called astrocytes, start to form nerve cells in the injured part of the brain. Using genetic methods to map the fate of the cells, the scientists could demonstrate that astrocytes in this area formed immature nerve cells, which then developed into mature nerve cells. ..."
