Good evening. Would you say you have a strong sense of intellectual curiosity? Since you are reading this blog, I imagine you probably do. I am writing this article for people like myself—those who aren’t experts but have a keen interest in neuroscience. Today, I’d like to explore the connection between intellectual curiosity and happiness, referencing a specific scientific paper.
I want to introduce a famous study regarding intellectual curiosity and memory. This paper presents experimental results showing that curiosity aids in the retention of information (Reference 1: M. J. Gruber et al., 2014). The study reveals that when intellectual curiosity is high, memory performance improves both immediately and one day later.
Furthermore, using fMRI (functional Magnetic Resonance Imaging), the researchers demonstrated increased activity in brain regions known as the midbrain and the nucleus accumbens. The authors suggest this indicates an increase in dopamine release (citing three supporting reasons within the paper), although it is not a direct measurement. While the primary focus of this study is the link to memory, if we consider the connection to happiness, it suggests a fascinating possibility: “By learning when our intellectual curiosity is piqued, we may experience a greater sense of well-being and euphoria.”
When I think of high intellectual curiosity, children immediately come to mind. Dealing with a child’s endless “Why? Why?” phase can be exhausting for parents, but answering them whenever possible might just be contributing directly to their happiness.
See you next time!

【Glossary(by Gemini)】
- fMRI (Functional Magnetic Resonance Imaging): A neuroimaging technology used to visualize which parts of the brain are active, as well as when and how that activity occurs.
- Midbrain: A region involved in essential functions such as life maintenance and motor control. It is also home to the Ventral Tegmental Area (VTA), which is responsible for releasing dopamine.
- Nucleus Accumbens: A key component of the brain’s reward system. It is the primary target for the dopamine released from the midbrain. When the nucleus accumbens receives dopamine, it generates a sense of euphoria or intense happiness.
