Neuroscientists have created 'mini brains' from human tissue that can FEEL and even suffer

An ethical line may have been crossed by neuroscientists who have created mini-brains from human tissue that can feel and may even suffer, experts have warned. So-called organoids are blobs of lab-grown tissue cultivated from human stem cells to resemble tiny organs -- in this case, the brain. Although these mini-brains may only be the size of peanut, they have been observed to develop spontaneous brainwaves, not unlike those that seen in premature babies. Organoids are considered a significant development in neuroscience, as they allow researchers to study brain tissue free of the usual constraints. These simulacra are used to investigate such disorders as autism and schizophrenia, and the impact of Zika virus on the development of brains in the womb.
