<div>Brain, Object, Landscape Dataset<br><br>Vision science - particularly machine vision - is being revolutionized by large-scale datasets. State-of-the-art artificial vision models critically depend on large-scale datasets to achieve high performance. In contrast, although large-scale learning models (e.g., AlexNet) have been applied to human neuroimaging data, the stimuli for such neuroimaging experiments include significantly fewer images. The small size of these stimulus sets also translates to limited image diversity. Here we dramatically increase the stimulus set size deployed in an fMRI study of visual scene processing. We scanned four participants in a slow-evented related design that incorporated 4,916 unique scenes. Data was collected over 16 sessions, 15 of which were task-related sessions, plus an additional session for acquiring high resolution anatomical scans. In 8 of the 15 task-related sessions, a functional localizer was run in order to independently define scene-selective cortex. In each scanning session, participants filled out a questionnaire (Daily Intake) about their daily routine, including: current status regarding food and beverage intake, sleep, exercise, ibuprofen, and comfort in the scanner. During BOLD scanning, physiological data (heart rate and respiration) was also acquired.</div><div><br></div><div>The experiment including 4,803 images presented on a single trial throughout the experiment, and 112 images repeated four times, and one image repeated three times, throughout the experiment, yielding a total of 5,254 stimuli trials. The stimuli were drawn from three datasets: 1) 1000 images from Scene Images (250 scene categories, based on SUN categories, with four exemplars each); 2) 2000 images from the COCO dataset; and 3) 1916 images from the ImageNet dataset. In the experiment, images were presented for 1 second, with 9 seconds of fixation between trials. Participants were asked to judge whether they liked, disliked, or were neutral about the image.</div><div><br></div><div>In sum, our dataset is unique in three ways: it is 1) significantly larger than existing slow-event neural datasets by an order of magnitude, 2) extremely diverse in stimuli, 3) considerably overlapping with existing computer vision datasets. Our large-scale dataset enables novel neural network training and novel exploration of benchmark computer vision datasets through neuroscience. Finally, the scale advantage of our dataset and the use of a slow event-related design enables, for the first time, joint computer vision and fMRI analyses that span a significant and diverse region of image space using high-performing models. <br><br>Please refer to our website for more details and future news and releases: BOLD5000.org <br><br>arXiv preprint in references below: https://arxiv.org/abs/1809.01281</div><div><br></div><div>v2: Added BOLD5000_ROIs.zip (9/7/18)</div><div>v3: Added BOLD5000_MRI-Protocols.zip (9/11/18)</div>
