Ella Striem-Ami. Can individual differences explain brain plasticity in blindness? Trends in cognitive sciences. 2024-10-23. PMID:39443277. |
explaining brain plasticity in blindness is challenging because the early visual cortex (evc) responds to many different tasks, each type supporting a different explanation. |

to define how early-life experience affects cortical dynamics in the visual cortex of adult, head-fixed mice, we examined the effects of two forms of blindness initiated before eye-opening and continuing through recording in adulthood: (1) bilateral loss of retinal input (enucleation) and (2) degradation of visual input (eyelid-suture). |
