Neuralink chip for human trials

US Food and Drug Administration (FDA) approved Elon Musk’s Neuralink chip for human trials. More on News • It aims to build a next-generation brain implant with at least 100 times more brain connections than devices currently approved by FDA. About Brain–Computer Interface (BCI) • A system that determines functional intent - the desire to change, move, control, or interact with something in our environment - directly from brain activity. o BCIs allow to control an application or a device using only our mind. • Main parts: o A device to detect and record signals coming from the brain. o A computer to process and analyze the recorded brain activity.

o An application/device to control. o A Feedback system.

• Different techniques to measure brain activity for BCIs o Electroencephalography (EEG) ✓ EEG is a test that measures electrical activity in the brain. o Functional Magnetic Resonance Imaging (fMRI) ✓ It works by detecting the changes in blood oxygenation and flow that occur in response to neural activity.
