Researchers at mit have been able to reprogram neurons in the brain of a living being.
In the experiment carried out on rodents, the team was able to deal with the neuroplasticity of the brain. It is known that the brain, including the human, can change under the influence of experience, as well as to restore after damage or in response to external influences, writes with reference to .
To better understand the principles by which neuroplasticity is manifested, doctors conducted the autopsy of the rodent skull rodent, after which some neurons in the primary visual cortex was introduced the gene for a protein GcaMP6 and others CHR2 gene that encodes the protein rhodopsin. GcaMP is a fluorescent protein that zastavliat neuron to emit light as it passes through a pulse. CHR2 — causes excitation of neurons in response to direct irradiation with light.
After that, the rodents began to perceive the points that they saw on the gray screen in front of him. Also, scientists were able to observe a number of processes associated with the “reprogramming”, and with the mechanisms of neuroplasticity — changes in the activity of protein receptors AMPA and resize connecting cell dendritic spines.
