Scientists are working on creating brain tissues in the lab to study cognition. They are using advanced techniques like bioprinting and growing neural organoids to build artificial brain structures. These bioengineered tissues show complex physiological patterns similar to real brains, including information processing. While they have basic signaling abilities, their potential for higher cognitive functions is still unknown. By combining different cell types in 3D structures, researchers hope to mimic real brain conditions and explore cognition in a dish.
