Scientists grow miniature brain that can contract muscleMarch 19, 2019 - 16:06 AMT PanARMENIAN.Net - Scientists have grown a miniature brain in a dish with a spinal cord and muscles attached, an advance that promises to accelerate the study of conditions such as motor neurone disease, The Guardian reports. The lentil-sized grey blob of human brain cells were seen to spontaneously send out tendril-like connections to link up with the spinal cord and muscle tissue, which was taken from a mouse. The muscles were then seen to visibly contract under the control of the so-called brain organoid. The research is is the latest in a series of increasingly sophisticated approximations of the human brain grown in the laboratory – this time with something approaching a central nervous system attached. Madeline Lancaster, who led the work at the Medical Research Council’s Laboratory of Molecular Biology in Cambridge, said: “We like to think of them as mini-brains on the move.” The scientists used a new method to grow the miniature brain from human stem cells, which allowed the organoid to reach a more sophisticated stage of development than previous experiments. The latest blob shows similarities, in terms of the variety of neurons and their organisation, to the human foetal brain at 12-16 weeks of pregnancy. However, the scientists said the structure was still too small and primitive to have anything approaching thoughts, feelings or consciousness. “It’s still a good idea to have that discussion every time we take it a step further,” said Lancaster. “But we agree generally that we’re still very far away from that.” Top stories Authorities said a total of 192 Azerbaijani troops were killed and 511 were wounded during Azerbaijan’s offensive. In 2023, the Azerbaijani government will increase the country’s defense budget by more than 1.1 billion manats ($650 million). The bill, published on Monday, is designed to "eliminate the shortcomings of an unreasonably broad interpretation of the key concept of "compatriot". The earthquake caused a temporary blackout, damaged many buildings and closed a number of rural roads.
