Introduction to Early Blind

What is/are Early Blind?

Early Blind - To test this hypothesis, normally sighted and early blind participants performed temporal order judgment tasks during which they judged which of two nociceptive stimuli applied on each hand’s dorsum was perceived as first delivered. ^[1] Here, we show that area hMT+, selective for visual motion in sighted individuals, responds to auditory frequency as well as auditory motion after early blindness. ^[2] Although several studies have demonstrated that congenital or early blindness correlates with modality-specific neural changes that reflect compensatory mechanisms, few have examined whether blind individuals show a learning advantage for auditory rhythms and whether learning can occur unintentionally and without awareness, that is, implicitly. ^[3] We compared performances of early blind and normally sighted participants during temporal order judgement tasks. ^[4] Results of two experiments comparing early blind and sighted individuals showed that SSC emerged strongly in both groups. ^[5] We also compared psychoacoustic performance between early blind (EB) subjects and late blind (LB) subjects. ^[6] Much less is known about the effects of early blindness on auditory cortex. ^[7] Purpose: Similar to early blindness, monocular enucleation (the removal of one eye) early in life results in crossmodal behavioral and morphological adaptations. ^[8] In the first case, most of the adoption takes place in the later informed period, while in the latter, all adoption takes place in the early blind period. ^[9] Experiment 2 studied in 91 other sighted adults the recognition of ASFGs produced by 10 early blind and 7 late blind adults. ^[10] While early blind individuals, even at the youngest ages, integrate audio-haptic information in an optimal fashion, late blind individuals do not. ^[11] We showed that early blind, late blind and sighted people do not differ in accuracy of sex and personality assessments based on body odor samples. ^[12] Neuroimaging studies in early blind (EB) patients have shown altered connections or brain networks. ^[13] Is vision necessary for the development of the categorical organization of the Ventral Occipito-Temporal Cortex (VOTC)? We used fMRI to characterize VOTC responses to eight categories presented acoustically in sighted and early blind individuals, and visually in a separate sighted group. ^[14] In this study, a novel early blind detection method has been proposed based on the color information extracted from retinal images using an ensemble learning algorithm. ^[15] The visual cortex of early blind individuals is reorganized to support cognitive functions distinct from vision. ^[16] In early blind individuals, brain activation by a variety of nonperceptual cognitive tasks extends to the visual cortex, while in the sighted it is restricted to supramodal association areas. ^[17] In all 6 studies, CXR interpretation was not clearly blinded to clinical information and the reference standard diagnosis was not blinded to CXR results. ^[18] Auditory spatial tasks induce functional activation in the occipital-visual-cortex of early blind humans. ^[19] It is well established that early blindness results in brain plasticity and behavioral changes in both humans and animals. ^[20] Highlights • ALE meta-analysis reveals distributed brain networks for object and spatial functions in individuals with early blindness. ^[21] This was tested by comparing performances of early blind and normally sighted participants during nociceptive temporal order judgment tasks. ^[22]
