Scientists discovered they could grow rat neurons in the tissue and then watch how it responded after an injury, incurred by dropping a weight on it, according to the study in the Proceedings of the National Academy of Sciences. While previous researchers have succeeded in making cultures made of collagen or hydrogel alone, this tissue was different because it lived longer and showed mechanical properties that were similar to real brain tissue. &quot;You can essentially track the tissue response to traumatic brain injury in real time,&quot; said senior author David Kaplan, chair of biomedical engineering at Tufts School of Engineering.</p><br clear="all"/>
