Creative tasks or stimuli, such as problem-solving tasks or creative prompts, are designed to elicit novel and original responses from individuals, often by presenting them with challenges or stimuli that require unique solutions or interpretations.These tasks typically involve engaging participants in divergent thinking, where they generate multiple possible solutions or ideas, and convergent thinking, where they evaluate and refine these ideas to arrive at a final solution (Cropley, 2006).For example, a problem-solving task may require participants to devise unconventional ways to overcome obstacles or achieve specific goals, while a creative prompt may encourage individuals to explore alternative perspectives or reinterpret familiar concepts in innovative ways (Dietrich & Kanso, 2010).Creative tasks and stimuli play a crucial role in experimental settings, as they provide researchers with a means to measure and manipulate creative thinking abilities, thereby facilitating the investigation of the neural underpinnings of creativity and innovation.
Neuroimaging techniques such as fMRI and EEG have been instrumental in elucidating the neural activity and brain regions associated with creative tasks and stimuli.Studies utilizing fMRI have identified increased activation in regions of the prefrontal cortex, such as the dorsolateral prefrontal cortex (DLPFC) and medial prefrontal cortex (mPFC), during creative tasks involving idea generation and problem-solving (Benedek & Fink, 2019).Similarly, EEG studies have revealed changes in neural oscillations, particularly in the alpha and gamma frequency bands, associated with different stages of creative thinking, such as idea generation and evaluation (Bhattacharya & Petsche, 2005).These findings highlight the importance of investigating both localized brain activity and network-level dynamics to gain a comprehensive understanding of the neural correlates of creativity and innovation.

Statement of Problem
Despite significant advancements in understanding the neural correlates of creativity and innovation, there remains a critical gap in our knowledge regarding how these processes manifest across diverse domains and contexts.While previous research has identified brain regions and networks associated with creative cognition, such as the prefrontal cortex and default mode network (Beaty, 2015;Benedek & Neubauer, 2013), much of this work has focused on specific domains such as visual art or scientific creativity.Consequently, there is a pressing need to investigate how neural mechanisms underlying creativity generalize across various domains, including but not limited to music, engineering, mathematics, and everyday problem-solving scenarios.Moreover, the contextual factors that modulate creative thinking, such as individual differences, socio-cultural influences, and task constraints, remain poorly understood.By addressing these gaps, we can gain a more comprehensive understanding of the neural basis of creativity and innovation, paving the way for targeted interventions to enhance creative thinking abilities across diverse populations and real-world contexts.

Conceptual Blending Theory
Originated by Gilles Fauconnier and Mark Turner, Conceptual Blending Theory posits that creativity arises from the process of blending different conceptual domains or mental spaces to create novel and meaningful ideas.This theory suggests that the human mind has the ability to integrate disparate concepts from various domains, resulting in innovative insights.In the context of the neural correlates of creativity and innovation, Conceptual Blending Theory is relevant as it provides a framework for understanding how the brain combines existing knowledge and experiences to generate novel ideas across different domains and contexts (Fauconnier & Turner, 1998).

Network Theory of Creativity
Proposed by Paul Thagard, the Network Theory of Creativity emphasizes the role of interconnected neural networks in creative thinking.According to this theory, creativity emerges from the dynamic interactions between distributed brain regions involved in diverse cognitive processes such as memory, attention, and problem-solving.By examining the network dynamics of creative cognition, researchers can gain insights into how the brain coordinates information processing to facilitate innovative thinking.In the study of the neural correlates of creativity and innovation, the Network Theory of Creativity offers a holistic perspective on the brain mechanisms underlying creative thought, highlighting the importance of examining neural connectivity patterns across domains and contexts (Thagard, 2010).

Four-Stage Model of Creativity
Developed by Graham Wallas, the Four-Stage Model of Creativity delineates four sequential stages in the creative process: preparation, incubation, illumination, and verification.This theory suggests that creativity involves a series of cognitive processes that unfold over time, from initial problem identification to the generation of novel solutions.In the context of the neural correlates of creativity and innovation, the Four-Stage Model provides a framework for investigating the temporal dynamics of creative thinking.By examining how neural activity evolves across different stages of the creative process, researchers can elucidate the underlying neural mechanisms that drive innovation in various domains and contexts (Wallas, 1926).
