On each block, participants (n = 20, performing the task in the fMRI scanner) viewed spirals of variable length associated with four options (bandits, indexed i).
(hmm, maybe I should move these weekly wrapups to Tuesday…) "The “morning scanners" view most content; late night readers click through more".
To permit off-line analysis of the explorations, the sessions were recorded by a video recorder located outside the scanner room viewing the subject close-up through a window.

13 Recent neuroimaging studies show that when participants lay quiet in an fMRI scanner, simply viewing objects that are typically manipulated by the hands activates "grasping circuits" 14 and visualization of favorite foods increases connectivity in the sensorimotor networks and cerebellum, regions in the brain known to be active in the pursuit of food.
In the scanner, they viewed the visual stimuli, projected from outside the scanner room, through a mirror located just in front of their eyes.
Scanning started at t = 120 min and lasted 45 min. Inside the MRI scanner, participants viewed a screen, placed at the head end of the scanner tunnel, via a mirror attached to the head coil.
To test these predictions, Kay and Naselaris went back into the scanner and viewed 120 photos they'd never seen before.
To identify neural representations of such abstract function concepts, we asked participants in an fMRI scanner to view a variety of objects and evaluate their utility to each of four goals (two Decoration goals: dress up for a night out and decorate a house, and two Protection goals: protect your body from the cold and keep objects dry in a flooded basement).
A week later, those participants were called back for a follow-up session inside an MRI scanner, and viewed fearful, surprised, and neutral faces.
