What is BOLD5000?

BOLD5000 is a large-scale, slow event-related fMRI dataset collected on 4 subjects, each observing 5,254 images over 15 scanning sessions. Our images are selected from three computer vision datasets.

  1. 1,000 images from Scene Images (with scene categories based on SUN categories)
  2. 2,000 images from the COCO dataset
  3. 1,916 images from the ImageNet dataset

Diverse Images

We incorporate the two core values of neuroscience and computer vision into one dataset. From neuroscience, we have taken a careful setup of slow event-related to ensure a stimulus to reponse mapping. From computer vision, we have taken some of the most iconic and standard benchmark images. We have indoor/outdoor scenes and a lot of naturalistic images. They're complicated and contain object to object interaction. Explore our images and check out our rich data.

Largest slow event-related fMRI dataset

BOLD5000 is a novel, large-scale, slow event-related fMRI dataset. There's over 5,000 images presented to each subject. Each subject was scanned for 16 sessions. That is a total of 96 hours of scanning done for this dataset!
