Sensory maps of the human brain are of great scientific interest and could have important medical applications. The sensory areas of the brain, including the auditory cortex, visual cortex, and more, contain topographical representations of the sensory space. Functional magnetic resonance imaging (fMRI) signals can produce subject-specific cortical maps, however, due to the low signal-to-noise ratio and spatial resolution, such maps are noisy, incomplete, and even contradict neurophysiological results.
Researchers at Arizona State University and a colleague at New York University have created a novel system for precise quantification of human sensory cortical areas which could be used in disease diagnoses and prognoses. This technology improves existing sensory mapping methods of the human brain by providing qualitative descriptions of sensory maps resulting in a rigorous imaging quantification framework. This system was applied to visual retinotopic maps and excellent results were generated.
This system makes it possible to precisely quantify sensory maps of individuals and further improved the quality of sensory maps with data from multiple individuals.
