Intramodal cortical plastic changes after moderate visual impairment in human amblyopia
2022, iScienceCitation Excerpt :Results indicated that individuals with amblyopia as well as late blind individuals performed better than sighted individuals. This could suggest that even those with mild visual impairment weighted the auditory cue information to a higher extent in this self-localization task compared to sighted individuals (Després et al., 2005). Evidence for compensatory neural plastic mechanisms in individuals with amblyopia have also been documented by investigating resting-state brain activity.
Motion processing after sight restoration: No competition between visual recovery and auditory compensation
2018, NeuroImageCitation Excerpt :It might be argued, that the persistence of the compensatory performance in auditory motion processing in the cc group was due to their prevailing low visual acuity after surgery rather than due to a transient phase of blindness from birth. Indeed, higher auditory skills have been reported in individuals with partial visual impairments (Despres et al., 2005a, 2005b). While we are not able to finally exclude a contribution of ongoing visual impairments to the cc group's superiority in auditory motion processing, we think this account cannot fully explain the cc individuals' superiority: First, cc individuals outperformed dc individuals in sound motion processing although these two groups' visual acuity did not significantly differ.
Electrophysiological correlates of mental navigation in blind and sighted people
2014, Behavioural Brain ResearchCitation Excerpt :In line with this assumption, our results indicate that the visual cortex is involved in spatial navigation in blind participants but not in sighted controls. Prior studies also found an involvement of the occipital cortex of blind people in diverse spatial tasks [5,14,21,24–28,37–40]. However, to the best of our knowledge this is the first study providing evidence for the functional reorganization of the visual cortex in blind people when using a more conventional mental navigation task on familiar routes.
Detecting spatial memory deficits beyond blindness in tg2576 Alzheimer mice
2013, Neurobiology of AgingCitation Excerpt :Conversely, in the Barnes maze, blind mice could rely on auditory and olfactory cues, as well as these motion-related information to establish spatial maps (Save et al., 1998) and successfully navigate to the target hole. In addition, blindness in humans and animals is associated with improved spatial hearing abilities and capacities of self-positioning from auditory cues (Després et al., 2005; King and Parsons, 1999; Lessard et al., 1998). Thus, our early blind mice most certainly used the auditory cues available with great efficiency to orient their spatial map and navigate through the maze.

2012, Acta PsychologicaCitation Excerpt :Indeed, this could have helped them in encoding piecemeal spatial information as a whole (Cattaneo et al., 2008; Millar, 1994; Thinus-Blanc & Gaunet, 1997). This would confirm that visual experience during the first years of life is crucial for later developments as it influences the cerebral architecture underlying the spatial processing systems (Cohen et al., 1997; Despres et al., 2005; Maurer et al., 2005). The similar performance of blindfolded and simultaneous sighted participants confirms that short term visual deprivation has a minimal impact on image scanning processes (Iachini & Ruggiero, 2010; but see Iachini & Giusberti, 2004).
