This study presents novel neuroimaging data of brain activity while participants watched a movie. The dataset enables new research into cognitive processes during naturalistic viewing experiences.
Area of Science:
- Cognitive Neuroscience
- Neuroimaging
Background:
- Traditional lab tasks lack real-world richness.
- Naturalistic stimuli like movies are increasingly used in cognitive neuroscience.
- Understanding brain function during naturalistic experiences is crucial.
Purpose of the Study:
- To describe a new dataset of cortical responses.
- To enable methods exploration in cognitive neuroscience.
- To facilitate the investigation of cognitive phenomena during naturalistic viewing.
Main Methods:
- Collected diffuse optical tomography (DOT) data from 58 healthy adults viewing a 10-minute movie clip.
- Mapped cortical responses across occipital, temporal, parietal, and frontal lobes.
- Quantified intersubject correlation and provided data in SNIRF and NIfTI formats.
Main Results:
- High-density DOT data were acquired from 106 viewing sessions.
- Cortical activity was mapped across extensive brain regions.
- Data demonstrate consistency across subjects for methods exploration.
Conclusions:
- The movie-viewing dataset offers a valuable resource for cognitive neuroscience research.
- This dataset supports the development of new analytical methods.
- It allows for the study of diverse cognitive processes in a naturalistic setting.

Imaging Studies III: Computed Tomography
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
