“…In contrast to our findings, Shibaski 9 ) found that a hand task activated the parietal lobes, whereas our findings showed greater activation of C3-C4. Somewhat similar to our findings, Aghababyan et al 10 ) found greater frontal, temporo-parieto-occipital activation during a creative task.…”

[Purpose] The objective of this study was to investigate changes from resting of the evoked cortical activity when participants performed three levels of therapeutic activities. [Subjects and Methods] Twenty-five students participated in this study. Changes in the amplitude of 16 pairs of evoked potentials were compared for three different activities: adjunctive, enabling, and purposeful. Data were analyzed using descriptive statistics and one-way ANOVA. [Results] Significant differences were found among the selected three activities for the Alpha 1 waveform. The complexity hierarchy was confirmed by descriptive statistics, as well as analyses of the three brain regions: central position (motor) Beta 1; parietal lobes, Beta 2, and occipital lobes, Alpha 1. In each instance, purposeful activity was confirmed as the most complex activity, followed by enabling, and then adjunctive. [Conclusion] This study will provide rehabilitation professionals with valuable information regarding what type of activity they should choose for a correct level of therapeutic challenge when they work with patients to plan meaningful interventions.

“…Algunos investigadores consideran que el hemisferio derecho expone durante el proceso de creación múltiples propuestas de ideas y asociaciones de manera burda y amplia, mientras que el izquierdo las organiza, cataloga o desecha acorde con la circunstancia. En ambas actividades se emplean tractos cortico-corticales inter e intrahemisféricos, lo que hace patente la interrelación bihemisférica en la creatividad (Petsche, 1996;Jausovec y Jausovec, 2000;Aghababyan et al, 2007). En resumen, en consonancia con los resultados observados, no existe un hemisferio creativo, sino la interacción de redes neuronales que comprometen ambos hemisferios en el proceso de creación.…”

El presente estudio pretende revisar las bases neuropsicológicas y neurobiológicas que subyacen al proceso de creatividad en el ser humano, considerando los resultados de estudios recientes sobre neuroanatomía funcional, genética y valoraciones neuropsicológicas. Mediante la reflexión crítica de estos resultados se pretende motivar al lector a la actualización de estos conocimientos, la aplicación de los mismos y la posible formulación de nuevas preguntas de investigación. De ese modo, la creatividad se puede medir con pruebas que incentivan el pensamiento divergente o el discernimiento interior. Los estudios de neuroimágenes funcionales aclaran con precisión las funciones cognitivas necesarias para la creatividad al localizarlas en estructuras cerebrales y demostrando su interrelación. Así pues, son útiles en el proceso de creatividad: la motivación, la apertura a lo novedoso, la inteligencia, la inspiración y la imaginación. Existen genes identificados que están relacionados con la creatividad. Igualmente, la creatividad se puede incentivar con la marcha, salidas al campo, ocio, reuniones multiculturales y el sueño. Los resultados expuestos en el presente estudio requieren replicación y análisis en contextos diferentes; así, se pueden abrir novedosas oportunidades de aplicación en muchas disciplinas y una apertura a nuevas preguntas de investigación sobre creatividad que permitan aclarar las bases funcionales y eventual traslación a la práctica cotidiana.

“…The first implies increased task-related alpha-power in frontal brain areas during creative tasks compared with baseline 44,46,[54][55][56][57] . The second relates to a hemispheric asymmetry with a righthemispheric dominance for alpha power 33,47,55,[58][59][60][61][62][63] . In line with these prior neurophysiological findings, it had been shown that bi-hemispheric activity in frontal sites and left-lateralized activity in central, temporal, and parietal sensor sites were predictors of an increase in originality 44 .…”

Emotions remarkably impact our creative minds; nevertheless, a comprehensive mapping of their underlying neural mechanisms remains elusive. Therefore, we explored the influence of induced emotional states on ideational originality and its associated neural dynamics. Participants were randomly presented with three short videos with sad, neutral, and happy content. After each video, ideational originality was evaluated using the alternate uses task (AUT). Ideational originality was significantly higher after induction of the happy state than the neutral state; in contrast, there was a nonsignificant difference between the sad and neutral states. Associated neural dynamics were assessed through EEG time-frequency (TF) power and phase-amplitude coupling (PAC) analysis. Our findings suggest that emotional states elicit distinct TF and PAC profiles associated with ideational originality. Relative to baseline, gamma activity was enhanced after the neutral induction and more enhanced after the induction of a happy state, but reduced after the induction of a sad state in 2-4 seconds after starting the task. Our PAC findings suggest that the attention system may be silent after the induction of a happy emotional state to load rich materials into working memory (WM) and active in the sad state to maintain these materials in WM.
