Brain technology:- a nuero chip that can communicate with brain

Technology is advance to the that much extent that today scientist have made a nuerochip that can communicate through brain.

The University of Calgary, Faculty of Medicine scientists who proved it is possible to cultivate a network of brain cells that reconnect on a silicon chip—or the brain on a microchip—have developed new technology that monitors brain cell activity at a resolution never achieved before.

Developed with the National Research Council Canada (NRC), the new silicon chips are also simpler to use, which will help future understanding of how brain cells work under normal conditions and permit drug discoveries for a variety of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s.

Naweed Syed's lab cultivated brain cells on a microchip.

The new technology from the lab of Naweed Syed, in collaboration with the NRC, is published online this month in the journal, Biomedical Devices

“This technical breakthrough means we can track subtle changes in brain activity at the level of ion channels and synaptic potentials, which are also the most suitable target sites for drug development in neurodegenerative diseases and neuropsychological disorders,” says Syed, professor and head of the Department of Cell Biology and Anatomy, member of the Hotchkiss Brain Institute and advisor to the Vice President Research on Biomedical Engineering Initiative of the U of C.

Brain cells communicate through electrical and chemical signals. Connections between synapses pass along chemical signals; electrical signals travel through ion channels, which are essentially gateways on the cell surface, as the Calgary Herald explains.

The new neurochips are also automated, meaning that anyone can learn to place individual brain cells on them. Previously it took years of training to learn how to record ion channel activity from brain cells, and it was only possible to monitor one or two cells simultaneously. Now, larger networks of cells can be placed on a chip and observed in minute detail, allowing the analysis of several brain cells networking and performing automatic, large-scale drug screening for various brain dysfunctions.
