<p>“The tissue still has enough structure to hold together but it is soft enough to allow the neurons to grow into each other and start talking to each other,” Zhang added.</p>

<p>Yuanwei Yan, a scientist in Zhang’s lab, said the tissues stayed relatively thin, which allowed the neurons to easily access oxygen and enough nutrients from the growth media.</p>

<h2><strong>Communication between neurons</strong></h2>

<p>The neurons communicate with each other, send signals and interact through neurotransmitters, and even form proper networks with support cells that were added to the printed tissue.</p>

<p>“We printed the cerebral cortex and the striatum and what we found was quite striking,” Zhang said. “Even when we printed different cells belonging to different parts of the brain, they were still able to talk to each other in a very special and specific way,” he added.</p>
