Data Acquisition

The data used is from the experiment described in [1]. Subjects passively viewed color images of six types of natural scenes: beaches, buildings, forests, highways, industry, and mountains). The stimuli were presented in a block design, with each block composed of 10 images from the same category displayed for 1.6 seconds each (8 brain acquisitions were made during each block). The subject viewed 12 runs of images, with each run composed of six blocks separated by 12 second fixation periods. (The original study also collected 12 runs with inverted images, but this data was not used for the current experiment).
