Scientists recently grew mini brains with their own sets of "eyes," according to a new study.
Organoids are miniature versions of organs that scientists can grow in the lab from stem cells, or cells that can mature into any type of cell in the body. Previously, scientists have developed tiny beating hearts and tear ducts that could cry like humans do. Scientists have even grown mini brains that produce brain waves like those of preterm babies.
Now, a group of scientists has grown mini brains that have something their real counterparts do not: a set of eye-like structures called "optic cups" that give rise to the retina — the tissue that sits in the back of the eye and contains light-sensing cells,
can the eyes sniff stuff like feet for example hahaLab-made mini brains grow their own sets of 'eyes'
