An outstanding issue in cognitive neuroscience concerns how the brain is organized across different conditions. For instance, during the resting-state condition, the brain can be clustered into reliable and reproducible networks (e.g., sensory, default, executive networks). Interestingly, the same networks emerge during active conditions in response to various tasks. If similar patterns of neural activity have been found across diverse conditions, and therefore, different underlying processes and experiences of the environment, is the brain organized by a fundamental organizational principle? To test this, we applied mathematical formalisms borrowed from quantum mechanisms to model electroencephalogram (EEG) data. We uncovered a tendency for EEG signals to be localized in anterior regions of the brain during “rest”, and more uniformly distributed while engaged in a task (i.e., watching a movie). Moreover, we found analogous values to the Heisenberg uncertainty principle, suggesting a common underlying architecture of human brain activity in resting and task conditions. This underlying architecture manifests itself in the novel constant <math>K_{brain}</math>, which is extracted from the brain state with the least uncertainty. We would like to state that we are using the mathematics of quantum mechanics, but not claiming that the brain behaves as a quantum object.
Un tema pendiente en la neurociencia cognitiva se refiere a cómo se organiza el cerebro en diferentes condiciones. Por ejemplo, durante la condición de estado de reposo, el cerebro se puede agrupar en redes confiables y reproducibles (por ejemplo, redes sensoriales, predeterminadas, ejecutivas). Curiosamente, las mismas redes emergen durante condiciones activas en respuesta a varias tareas. Si se han encontrado patrones similares de actividad neuronal en diversas condiciones y, por lo tanto, diferentes procesos subyacentes y experiencias del entorno, ¿está el cerebro organizado por un principio organizativo fundamental? Para probar esto, aplicamos formalismos matemáticos tomados de mecanismos cuánticos para modelar datos de electroencefalograma (EEG). Descubrimos una tendencia a que las señales de EEG se localicen en las regiones anteriores del cerebro durante el "descanso" y se distribuyan de manera más uniforme mientras se realiza una tarea (es decir, ver una película). Además, encontramos valores análogos al principio de incertidumbre de Heisenberg, lo que sugiere una arquitectura subyacente común de la actividad del cerebro humano en condiciones de reposo y de tarea. Esta arquitectura subyacente se manifiesta en la novela constante <math>K_{brain}</math>, que se extrae del estado del cerebro con la menor incertidumbre. Nos gustaría afirmar que estamos usando las matemáticas de la mecánica cuántica, pero sin afirmar que el cerebro se comporte como un objeto cuántico.
