Abstract

fetched live from OpenAlex

The brain shows a remarkable capacity to reorganize itself following early sensory deprivation or neonatal brain damage. Using two models of deprivation, we will show that the brain does indeed adjust to the loss of either the visual cortex (which receives most of the retinal inputs through the lateral geniculate bodies of the thalamus) or the eyes (which provide the major input to the visual cortex) through cross-modal plastic processes. Hamsters, deprived of their visual system at birth, develop novel and permanent retinal projections to the auditory thalamus. These projections form functional synapses and project to the auditory cortex. When trained on a visual discrimination task, the "rewired" hamsters perform as well as normal hamsters. Lesions of the auditory cortex produce cortical blindness. Congenitally blind human subjects, trained to discriminate the orientation of a stimulus applied to the tongue via an electrotactile device, show activation of their visual cortex, whereas trained blindfolded controls show only activation of the somatosensory cortex representing the tongue. We propose that in blind subjects, there is an unmasking of existing cortico-cortical (parieto-occipital) connections, enabling transfer of somatosensory information to visual cortex.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
