Brain organoid reservoir computing for artificial intelligence Brain-inspired computing hardware aims to emulate the structure and working principles of the brain and could be used to address current limitations in artificial intelligence technologies. However, brain-inspired silicon chips are still limited in their ability to fully mimic brain function as most examples are built on digital elec..

https://www.nature.com/articles/nature12517 (28 August 2013)Cerebral organoids model human brain development and microcephaly    Abstract The complexity of the human brain has made it difficult to study many brain disorders in model organisms, highlighting the need for an in vitro (실험 환경 상에서) model of human brain development. Here we have developed a human pluripotent stem cell-derived (줄기세포) th..
