TLDR
The orderly representations of sensory surfaces in the brains of adult mammals have the capacity to reor ganize after injuries that deprive these representations of some of their normal sources of activation.Abstract:
The orderly representations of sensory surfaces in the brains of adult mammals have the capacity to reor ganize after injuries that deprive these representations of some of their normal sources of activation. Such reorganizations can be produced by injury that occurs peripherally, such as nerve damage or amputation, or after injury to the CNS, such as spinal cord damage or cortical lesion. These changes likely are mediated by a number of different mechanisms, and can be extensive and involve the growth of new connections. Finally, some types of reorganizations may help mediate the recovery of lost functions, whereas others may lead to sensory abnormalities and perceptual errors. NEUROSCIENTIST 3:123-130, 1997read more

Critical periods of vulnerability for the developing nervous system: evidence from humans and animal models.
Deborah C. Rice,Stan Barone +1 more
TL;DR: Of critical concern is the possibility that developmental exposure to neurotoxicants may result in an acceleration of age-related decline in function, and the fact that developmental neurotoxicity that results in small effects can have a profound societal impact when amortized across the entire population and across the life span of humans.

Treatment-Induced Cortical Reorganization After Stroke in Humans
TL;DR: This is the first demonstration in humans of a long-term alteration in brain function associated with a therapy-induced improvement in the rehabilitation of movement after neurological injury.

Forebrain mechanisms of nociception and pain: analysis through imaging.
TL;DR: An animal model for investigating stimulus-induced rCBF responses in the rat is developed and it is shown that there is a progressive and selective activation of somatosensory and limbic system structures in the brain and brainstem following the subcutaneous injection of formalin.

Extensive reorganization of the somatosensory cortex in adult humans after nervous system injury
Thomas Elbert,Herta Flor,Niels Birbaumer,Stefan Knecht,S. Hampson,Wolfgang Larbig,Edward Taub +6 more
TL;DR: In this article, magnetic source imaging revealed that the topographic representation in the somatosensory cortex of upper extremity amputees was shifted an average of 1.5 cm toward the area that would normally receive input from the now absent nerves supplying the hand and fingers.

Peripherally induced oromandibular dystonia
TL;DR: The study indicates that oromandibular-facial trauma, including dental procedures, may precipitate the onset of OMD, especially in predisposed people, and prompt recognition and treatment may prevent further complications.

Perceptual correlates of massive cortical reorganization.
TL;DR: In patient VQ, stimuli applied to the lower face or 7 cm above the stump evoked precisely localized referred sensations in individual digits which were often modality specific, indicating the emergence of such maps in regions remote from the stump.

TL;DR: Observed alterations provide evidence for extensive plastic reorganization in the adult human cortex following nervous system injury, but they are not a sufficient cause of the phantom phenomenon termed 'facial remapping'.

The presence of ineffective synapses and the circumstances which unmask them.
TL;DR: The presence of ineffective synapses in the adult offers an alternative to sprouting or the opening up of polysynaptic pathways as a possible mechanism to explain plasticity of connections in adult brains.

Development and Plasticity of Neocortical Processing Architectures
TL;DR: It is proposed that the cortex applies two complementary strategies to cope with the combinatorial problem posed by the astronomical number of possible relations: the analysis and representation of frequently occurring, behaviorally relevant relations by groups of cells with fixed but broadly tuned response properties; and the dynamic association of these cells into functionally coherent assemblies.
