Is it possible to 3d print a neuronal structure with a different material than neurons that would work just like a neuron with membrane potential?
Ryan_m_b said:Neurons are micro-scale cells (in most axes). As far as I'm aware 3D printing is not capable of that sort of resolution. Further more neurons are dynamic, they have to be able to change in response to their environment. No only do they have to alter synaptic strength but be capable of metabolism, self repair, growth etcetera. A purely static object won't be "just like" a neuron.
fredreload said:Can't you get a material similar to neuron that is capable to transmit signal? I mean for a synthetic limb you wouldn't need self repair and growth if you get the right material. The brain plasticity can get a bit tricky but the brain eventually becomes static. The material does not need to behave like a cell, it just need to have a membrane potential for transferring ions.
fredreload said:Once they work out the senses, they still need to provide the sort of muscle contraction like this for the prosthesis. This got me worried as to if it would become a technical issue. But after all, the arm is just consisted of muscle, bone, nerve, sense of touch and pain. Once they get muscle contraction to work it should come pretty close to being a real limb.
fredreload said:There should be a working carbon nanotube synapse by now right? Most of it is in the thesis paper by 2011 and 2013.
3D printing of neurons with membrane potential is a process of creating three-dimensional models of nerve cells using a specialized printer. These models are designed to mimic the structure and function of real neurons, including the ability to generate and transmit electrical signals.
The materials used in 3D printing neurons with membrane potential vary depending on the specific printer and technique used. However, common materials include biocompatible polymers, hydrogels, and conductive materials such as graphene or silver nanoparticles.
3D printing neurons with membrane potential has several potential applications in neuroscience research and medicine. It can be used to better understand the structure and function of neurons, create models for drug testing and disease study, and even facilitate the development of neural prosthetics.
The accuracy of 3D-printed neurons with membrane potential depends on the resolution and precision of the printer used. With advanced techniques and high-quality materials, it is possible to create models that closely resemble real neurons in terms of size, shape, and electrical properties.
At this time, 3D-printed neurons with membrane potential are not developed enough to be used for transplantation in humans. However, there is ongoing research and experimentation in this area, with the goal of eventually being able to create functional neurons for therapeutic purposes.
