Brain tissue is the most difficult type of organic matter to create in a lab setting, typically lasting for less than a day before dying; however the new bioengineered brain tissue from researchers at Tufts has remained viable for several weeks and develops complex neuronal activity that mimics living brain tissue. It even organized itself into brain-like structures and created distinct grey and white brain matter, as detailed in their report “Bioengineered functional brain-like cortical tissue”, published in Proceedings of the National Academy of Sciences (PNAS).
…Under close examination, the 3D brain matter showed the same sorts of electrical activity that a fully functional brain would show. This made it possible for the researchers to carry out several experiments intended to examine how the brain reacted to different sorts of drugs. They also caused damage to the tissue,to mimic a traumatic brain injury. Altogether, these experiments were intended to compare their results to similar experiments carried out with animal brains. Early results showed promising similarities between both experiments, meaning that their bioengineered tissue could create a viable alternative to the use of animals in these sorts of tests.
With lab-created brain matter this complex and viable for such a long period of time, the researchers are able to follow the tissue response to the initial damage over time, as well as how the matter begins to repair and reconstruct itself after injury. This could drastically improve the amount of information we are able to learn about how the brain reacts after receiving damage, and hopefully lead to new advancements on reversing traumatic brain injury….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
