Shedding light on brain function: the event-related optical signal

摘要: One of the basic goals cognitive psychology is analysis covert processes that occur between stimulus and response. In past 20-30 years, tools available to psychologists have been augmented by a number imaging techniques for studying 'brain in action' non-invasive manner. These their strength either temporal or spatial information, but not both. We review here recent advances new approach, event-related optical signal (EROS). This method allows measurements time course neural activity specific cortical structures, thus combining good specificity. As an example, we show how EROS can be used distinguish serial parallel models information processing.
