Electrical microstimulation allows researchers to map the brain for the first time

Over the last two centuries electrical microstimulation has been often used to demonstrate causal links between neural activity and specific behaviors or cognitive functions. However, to understand the mechanisms by which electrical microstimulation can cause alternations in behaviors and cognitive functions it is imperative to characterize the cortical activity patterns that are elicited by stimulation locally around the electrode and in other functionally connected areas.
