Scientists have successfully grown a human brain in a jar. My question is not whether this should be done -it has been done (though you can speak to this too if you wish) but given that one has a living brain in a jar what should be done with it (him/her?). Please discuss your vote.
"“We’re talking about the very first steps of embryonic brain development, like in the first nine weeks of pregnancy,” Knoblich said.
...Using molecular markers tuned to specific parts of the brain, Lancaster showed that the organoids develop a variety of distinctive zones that correspond to human brain regions like the prefrontal cortex, occipital lobe, hippocampus, and retina. They also included working neurons, which were produced in the right way—they were made by radial glial cells at the innermost layers of the cortex, before migrating to the outer layers.
Other scientists have developed organoids that mimic several human organs, including eyes, kidneys, intestines, and even brains. For example, in 2008, Yoshiki Sasai’s team at the RIKEN Center for Developmental Biology showed that stem cells can be coaxed into balls of neural cells that self-organize into distinctive layers. But compared to this earlier attempt, the new organoids are “the most complete to date, in terms of features that directly resemble those in the developing human brain,” according to Arnold Kriegstein, a stem cell biologist from the University of California, San Francisco, who was not involved in the study."
