Brain implant between neural systems and computer chips. This work is part of a wider research field called brain-computer interfaces. (Brain-computer interface research also includes technology such as EEG arrays that allow interface between mind and machine but do not require direct implantation of a device.) Neural implants such as deep brain stimulation and Vagus nerve stimulation are increasingly becoming routine for patients with Parkinson's disease and clinical depression respectively. Brain implants electrically stimulate, block or record (or both record and stimulate simultaneously) signals from single neurons or groups of neurons (biological neural networks) in the brain. The blocking technique is called
The Boston process approach the outcomes to make conclusions on what is going on in the brain. These conclusions are based on the errors that occurred during the test. The point of looking at the errors is to see what issues may have occurred when trying to process the information and answer the question in order to evaluate the specific deficit(s). Certain inaccuracies may infer that there’s damage to a definite part of the brain, like speech difficulties implicating the speech area in the left hemisphere. The qualitative analysis focuses on closely observing the process by which a patient arrives at a final answer.
