Abstract: Ensemble neuronal activity is believed to create cognition and consciousness, in accordance with the Hebian “cell assembly” hypothesis about brain function via interconnected neuronal networks. While specific experimental conditions are set up, functional recording techniques are used to record/monitor the brain, and the more they improve the better. The common experimental results from such techniques are to be used as to monitor brain function, after setting up two (or more), different but very similar experimental conditions. This method aims to elucidate just a part of a mental representation, trying to find the end of the thread in unraveling all of it, if possible. The method main idea is to compare results coming from similar experimental conditions and it is applicable to any field and not only neuroscience.
