| fMRI_responses {shuffle} | R Documentation |
Responses for 30 voxels (of V1) to 1560 stimuli.
Description
A 30x1560 data matrix consisting of a sample of 30 fMRI responses from the visual cortex V1 of a human subject, to a sequence of natural images. The treatment index is found in design_vec.
Usage
data(fMRI_responses)Format
A 30x1560 matrix of real values. Each row corresponds to a different voxel.
Details
Measurement were recorded as a person was watching a sequence of natural images. Each column corresponds to a displayed image; each row corresponds to the response of a single voxel in the fMRI scan. This data consists of a small subset of the voxels in V1 from the original scans. The data was recorded in the Gallant lab at UC Berkeley.
