Observe the development of brain cells according to the real-time system

For the first time, a researcher from the Hebrew University of Jerusalem succeeded in observing the bioavailability (in vivo) of neurons in the brains of mammals.

Dr. Adi Mizrahi of the Department of Neuroscience at the Hebrew Institute for Life Sciences Alexander Silberman, used a model of experiments on mice to study how neurons and neurons grow. From the sphere, there is an infinite cell structure that forms healthy and complex cells.

This is of great importance for future brain research, said Dr. Mizrahi: 'The complexity of the structure and function of nerve cells still remains one of the great mysteries. the largest of the neuroscience, and now we have a model to directly study this complexity. "

Using special microscopic imaging techniques in combination with viral genetics, Dr. Mizrahi was able to develop an experimental model to study the development of neural branches ( dendrite ) in vivo. . These neuron branches are like diffuse strands of neurons, stretching out and touching other neurons and responding in the form of information between neurons together.

The model hired by Dr. Mizhari in his research is the number of newborn neurons that develop into the olfactory bulb of large mice, providing them with the ability to smell. The development and maintenance of newborn neurons in this zone is estimated by the number of images over a period of several days at various stages of development.

Mizrahi revealed: "The formation of the neuron branch is very high. Moreover, once consolidated into a system, long-born neurons are constantly changing dynamically and maturing. This method provides giving us the technique to observe, for the first time in mammals, how a neuron develops and how strong and complex the cell wall is, only once developed, neurons are sustained. maintenance in the changing environment and high activity of the brain. "

Dr. Mizrahi notes: 'There are only a few small areas in the brain that are likely to be the causes of neurology, and they hide the secrets we want to explore.
