Classical philosophies on blindness and cross-modal transfer, 1688–2003
Published in John Ravenscroft, The Routledge Handbook of Visual Impairment, 2019
Similarly, studies of so-called cross-modal plasticity, where vision is removed and the mind has to rely on other sensory data, shows that sensory images can adapt to rely on other sensory data. For example, research with people who have significant visual impairments has shown that what is called the visual cortex in the brain can be stimulated by touch (Sathian and Stilla, 2010) – this research subsequently questions whether the visual cortex is designed to process vision alone, as was traditionally thought.
Mechanisms of Recovery After Acquired Brain Injury
Published in Barbara A. Wilson, Jill Winegardner, Caroline M. van Heugten, Tamara Ownsworth, Neuropsychological Rehabilitation, 2017
Although spontaneous recovery, network recovery and behavioural compensation adaptation processes after brain injury may lead to functional improvements, the most powerful booster of cortical and functional progress is obviously experience-dependent recovery. Cortical and functional changes are most striking in, so-called, cross-modal plasticity, in which the loss of a sensory function due to disease or brain damage strengthens other sensory functions and induces extensive plastic reorganisation of brain areas.
Exploration of a novel physical therapy protocol that uses a sensory substitution device to improve the standing postural balance of children with balance disorders

We speculate that cross-modal plasticity could be responsible for the standing postural balance improvements seen in this exploratory study. A sensory substitution device works on the principle of reweighting sensory information by increasing the reliance on alternative pathways in the absence of a particular sensory modality (Bach-y-Rita and Kercel, 2003). Thus, we speculate that BrainPort might have promoted cross-modal plasticity by providing a reliable mechanical interface to transmit balance-related sensory information to the other parts of the brain in absence of vestibular and/or proprioceptive input (Bach-y-Rita, 2004; Duffau, 2006; Poirier, De Volder, and Scheiber, 2007). Our assumption is based on the outcomes of prior studies showing that a sensory substitution device induced cross-modal plasticity in the blind (Bach-y-Rita et al., 1969; Matteau et al., 2010; Ptito, Moesgaard, Gjedde, and Kupers, 2005) and in patients with stroke (Badke et al., 2011). This reasoning might also explain the differences in our sub-groups because children with DCD may not have difficulty with a lack of sensory information, in comparison to the other groups. Although these speculations are plausible, there still is a need for a study that employs brain imaging to challenge these assumptions. Moreover, further research comparing intensive balance training alone with the balance training combined with the BrainPort device is warranted. This will delineate the BrainPort induced changes as opposed to changes induced by practice in improving the balance of children with balance deficits.

If the auditory pathway is not stimulated in children with congenital deafness, other sensory modalities such as vision or proprioception take over the functional area of the auditory cortex: – this is termed as cross modal plasticity (selected bibliography in Table A1). Limited data exists on what happens in the auditory cortex in the presence of PD. Clinically, a significant proportion of children with PD display speech and language deficits that appear to be irreversible (Zgoda et al., 2012; Tzifa et al., 2013; Wilson et al., 2016). This indicates that any symptomatic PD pediatric patient should be identified early via electrophysiological and speech pathology testing and treated as early as possible like other children with profound sensorineural hearing loss.
Ultrabilitation: beyond recovery-oriented rehabilitation
Published in Disability and Rehabilitation, 2019

Denied input from one sensory modality such as vision, the brain can sometimes reorganize itself to augment intact sensory systems. This mechanism of “cross-modal” plasticity could help to explain why impaired vision may be a resource associated with functional improvement of hearing, touch and verbal memory, even beyond species-typical levels [17]. Providing certain perceptual information or tasks may also produce “supra-modal” plasticity, which refers to how the brain may reorganize itself independently of particular sensory input. In persons who are blind, supra-modal plasticity is the reorganization that takes place despite the lack of vision, whereas cross-modal plasticity is what happens because of the lack of vision [47].
