For the first time created artificial neurons suitable for transplantation
Source:the Creation of artificial neurons — a real breakthrough
What do you imagine, if you will hear the term «artificial neurons»? Probably something like a wire-coated, which we exhibit regularly in sci-Fi movies. However, everything in life is not quite so. Although, admittedly, no less futuristic and interesting. For example, an international group of scientists recently invented artificial neurons on a silicon chip that behaves like the real thing. This is the first of its kind device of this kind. Which, moreover, suitable for transplantation to humans.
Why do we need artificial neurons?
at the University of Bath (UK), new artificial is perfect for the treatment of chronic diseases such as heart failure, Alzheimer's disease and other problems associated with the degeneration of nerve fibers. It is critical that the artificial neurons do not only behave the same as biological neurons, but almost need no power supply (supply built-in battery «enough for life»), which makes them ideal for use in medical implants and other bioelectrical devices.
The Research team led by the University of Bath and involving researchers from the universities of Bristol, Zurich and Auckland, argues that the artificial neurons respond to electric signals from the nervous system, like the real thing, then tried to get many for decades.
This opens the possibility of treatment processes in which the neurons are not working properly. Their pathways were interrupted, as in a spinal cord injury, or nekrotizirovanne due to other diseases. Artificial neurons can restore these relations, reproducing them healthy function and adequately responding to biofeedback for the functioning of the whole organism. — scientists say
Here is the main part of the artificial neuron.
Experts Also cite an example of the use of technology. For example, in heart failure, neurons in the brain do not respond properly to , and they in turn send the right signals to the heart that is not functioning as it should. Replace «broken» artificial neurons solves this problem. About these developments we often write on our site, so don't miss the most important.
One of the main difficulties in the development was non-linear response of the neurons. Reactions of the neurons can be unpredictable: if we send the signal is very strong, then it is not necessary that the response will be similar. Mathematical calculations and rigorous simulations taking into account these nonlinear reactions allowed to create artificial neurons that respond to incentives as it would be done by living healthy tissues.
After the exclusion of patterns on mathematical models, scientists have developed silicon chips that accurately reproduce biological ion channels (one of the major components that contribute to the conductive function of neurons) before to prove that they «silicon neurons» exactly imitated the actual work.
Until now, the neurons were similar to «black boxes», but we managed to open the black box and look inside. Our work changes the paradigm because it gives doctors a reliable method to reproduce the electrical properties of real neurons in the smallest details. — says project Manager Allen Nogaro, Professor, physics Department, University of Bath.
The Creation of such neurons suggests that it is now possible to replace with them using old or already dead pathways and cells to restore various body functions. In particular, the new invention will be useful for patients with a developing Alzheimer's disease and other similar conditions.
