Still, he says, what he and his ASU colleagues have learned is sufficient enough to at least establish the hemisphere of motion. The ASU scientists are now working to modify specific mathematical algorithms that Schwartz developed so that they work with simultaneous signals. The team must also study how factors such as fatigue and motivation levels of the subject might alter neuro-responses to stimulus. We're really on the forefront of this area of research. All this data can get pretty confusing.
Cell firing patterns are extremely complex.
They record this data for each cell they study. That adds up to a lot of data. Team members can display the information by charting a series of spikes, which represent the firing of cells over a period of time. Even a simple arm motion can produce hundreds of spikes from each brain cell involved. The relevant brain data used by the team members is in the form of firing rates.
