Human cerebral organoids and consciousness: a double-edged sword.
Human cerebral organoids (HCOs) are three-dimensional in vitro cell cultures that mimic the developmental process and organization of the developing human brain. In just a few years this technique has produced brain models that are already being used to study diseases of the nervous system and to test treatments and drugs. Currently, HCOs consist of tens of millions of cells and have a size of a few millimeters. The greatest limitation to further development is due to their lack of vascularization. However, recent research has shown that human cerebral organoids can manifest the same electrical activity and connections between brain neurons and EEG patterns as those recorded in preterm babies. All this suggests that, in the future, HCOs may manifest an ability to experience basic sensations such as pain, therefore manifesting sentience, or even rudimentary forms of consciousness. This calls for consideration of whether cerebral organoids should be given a moral status and what limitations should be introduced to regulate research. In this article I focus particularly on the study of the emergence and mechanisms of human consciousness, i.e. one of the most complex scientific problems there are, by means of experiments on HCOs. This type of experiment raises relevant ethical issues and, as I will argue, should probably not be considered morally acceptable.
期刊介绍:
Monash Bioethics Review provides comprehensive coverage of traditional topics and emerging issues in bioethics. The Journal is especially concerned with empirically-informed philosophical bioethical analysis with policy relevance. Monash Bioethics Review also regularly publishes empirical studies providing explicit ethical analysis and/or with significant ethical or policy implications. Produced by the Monash University Centre for Human Bioethics since 1981 (originally as Bioethics News), Monash Bioethics Review is the oldest peer reviewed bioethics journal based in Australia–and one of the oldest bioethics journals in the world.
An international forum for empirically-informed philosophical bioethical analysis with policy relevance.
Includes empirical studies providing explicit ethical analysis and/or with significant ethical or policy implications.
One of the oldest bioethics journals, produced by a world-leading bioethics centre.
Publishes papers up to 13,000 words in length.
Unique New Feature: All Articles Open for Commentary
