Activation of the primary visual cortex by Braille reading in blind subjects
In blind subjects, cortical areas normally reserved for vision may be activated by other sensory modalities, and positron emission tomography was used to determine whether the visual cortex receives input from the somatosensory system.

Functional relevance of cross-modal plasticity in blind humans
It is concluded that blindness from an early age can cause the visual cortex to be recruited to a role in somatosensory processing and proposed that this cross-modal plasticity may account in part for the superior tactile perceptual abilities of blind subjects.
Modeling other minds
Nine normal volunteers performed a ‘theory of mind’ task while their regional brain blood flow pattern was recorded using the PET [15O]H2O technique, suggesting that when inferential reasoning depends on constructing a mental model about the beliefs and intentions of others, the participation of the prefrontal cortex is required.

It is indicated that the susceptible period for this form of functionally relevant cross‐modal plasticity does not extend beyond 14 years, in subjects who became blind after age 14 years (late‐onset blind), after a lengthy period of normal vision.
Critical Period for Cross-Modal Plasticity in Blind Humans: A Functional MRI Study
The primary visual cortex (V1) in congenitally blind humans has been shown to be involved in tactile discrimination tasks, indicating that there is a shift in function of this area of cortex, but the…

Using a proper control condition and two measures of preferences (self-report and brain activity), it is found that the mere act of making a choice can change self-report preference as well as its neural representation, thus providing strong evidence for choice-induced preference change.

The posterior SMA and right PMd appear to be related to the bimanual coordination of finger movements, and areas with changes of rCBF during bimanUAL finger movements of different characteristics were detected.
