科学家正逐步接近在实验室中"培育出"人类大脑的能力，这引发了关于这些实验室培养组织"福利"的伦理争论。 作者们认为，关于类器官研究的相关法规应重新审查。约翰斯·霍普金斯大学的神经科学家博伊德·洛马克斯（Boyd Lomax）表示，让有意识的类器官产生 自己的思想或感受疼痛是"不道德的"。 争议的核心是"类脑器官"，它们有时被误认为是科幻小说中"缸中之脑"。实际上，这些由干细胞培育而成的小块脑组织过于简单，无法像真正的人脑那样 运作。因此，科学界普遍认为类脑器官缺乏意识，从而导致相关研究的监管较为宽松。 但并非所有科学家都同意这种观点。 浙江大学的生物伦理学研究者克里斯托弗·伍德（Christopher Wood）表示："我们认为，在害怕炒作和科幻夸张的影响下，学界的立场已经摆动得太远 了。"伍德与同事在9月12日发表于《Patterns》[1]期刊的观点文章中指出，技术的进步可能很快就会让"有意识的类器官"成为现实。 然而，如何界定"意识"，并非易事。 意识难以定义 用于制造类脑器官的干细胞在二维平面上（例如培养皿）并排生长，缺乏复杂的结构组织。但当它们在固体凝胶或旋转式生物反应器中悬浮生长时，就会 形成三维 ...
