Placebo-Induced Changes in fMRI in the Anticipation and Experience of Pain
fMRI experiments found that placebo analgesia was related to decreased brain activity in pain-sensitive brain regions, including the thalamus, insula, and anterior cingulate cortex, and was associated with increased activity during anticipation of pain in the prefrontal cortex, providing evidence that placebos alter the experience of pain.

Changes in cortical activity during mental rotation. A mapping study using functional MRI.
Functional MRI was used to observe focal changes in blood flow in the brains of 10 healthy volunteers performing a mental rotation task, and data are consistent with the hypothesis that mental rotation engages cortical areas involved in tracking moving objects and encoding spatial relations.
Mental rotation of objects versus hands: neural mechanisms revealed by positron emission tomography.
The results suggest that at least two different mechanisms can be used in mental rotation, one mechanism that recruits processes that prepare motor movements and another mechanism that does not.

Understanding charts and graphs
A way of analyzing the information in charts and graphs that reveals the design flaws in the display that is derived from facts about human visual information processing and from an analysis of the nature of symbols.
Concept development.
Evidence for two types of spatial representations: hemispheric specialization for categorical and coordinate relations.
Results indicate that Ss make categorical judgments--on/off, left/right, and above/below--faster when stimuli are initially presented to the left cerebral hemisphere, whereas they make evaluations of distance--in relation to 2 mm, 3 mm, or 1 in.
Neural foundations of imagery
Neuroimaging studies, combined with other methods, are revealing the ways in which imagery draws on mechanisms used in other activities, such as perception and motor control.
