It has been a decade long pursuit to decipher the neurological functioning of Alzheimer’s disease as well as Parkinson’s disease. Medical biology has developed various procedure to understand the neurological function in these diseases. With the advancement of technology, the medical biologist has come up with a new type of wireless-powered and battery-less chip that could be implanted inside the individual’s brain surgically, which has the function of stimulating the brain with both light and electrical current.
The feature which makes this chip advance from the rest of the technologies and procedure is that it has 5X3 mm2 chip, which contains an integrated power receiver coil. The power can be generated by applying the electromagnetic field, thus making it wireless and capable of sending and receiving signals. Another additional feature being trimodal, capable of performing three tasks. This new chip can read neural signals sent to the targeted region of the brain by introducing small electric current into brain tissue. As well as it can also shine light onto the brain tissue, but for this optical stimulation, the neural cells have to be genetically modified, for making them respond to the light of specific wavelength. Thus making it easy for easy detection of the neural function in the brain.
Although the research was conducted on rats yet the result on humans remains under dark. Will it be a new evolution in the biomedical field?
