Stimulus Independent Thoughts (SITs)
n. Daydreaming or other thoughts unrelated to one’s current task or activity.
Contemporary neuroscientists have described a neural network associated with what they label as stimulus independent thoughts (SIT), a cortical network which is active when the brain is supposedly at rest. SIT, or “mind-wandering,” is a phenomenon generated during times of non-purposeful attention.
