Humans with damage to primary visual cortex (V1) are for most purposes blind, although in some circumstances they can "guess" accurately about stimuli they do not consciously see (blindsight); if the damage occurs early in life recovery can be very good and include some awareness of stimuli. This project assesses the role of cells in the visual thalamus in the improved recovery via a monkey model. This year, subjects with V1 damage were prepared and assessed via MRI. Single-unit recording and anatomical studies of the thalamus will be performed in these subjects.

对于大多数人来说，初级视觉皮层（V1）受损的人 目的是盲目的，尽管在某些情况下他们可以“猜测” 准确地了解他们无意识看到的刺激（盲视）；如果 生命早期发生的损害可以得到很好的恢复，包括 对刺激有一定的认识。 该项目评估了细胞在 通过猴子模型改善视觉丘脑的恢复。 这 今年，V1 损伤的受试者通过 MRI 进行了准备和评估。 丘脑的单单位记录和解剖研究将 在这些科目中进行。
