Neuroscience has longed to map the human brain in real time; MRI is a great tool, but it’s a passive scan that can only describe a ‘rest state’, a mere snapshot of the activity. Finnish company Nexstim has taken the next step by developing a procedure called Navigated Brain Stimulation, or NBS. Their device can target electromagnetic stimuli in specific parts of the brain of a patient, and then measure the effects via EEG in real-time, allowing for far more effective diagnosis of dysfunction.
