距状沟皮层可能有助于早期失明(EB)的语义识别记忆。我们使用振动触觉节律和检索成功范式评估了识别记忆的作用,该范式涉及 EB 和视力者中习得的“旧”和“新”节律。 EB 显示枕叶皮层没有激活差异,表明检索成功,但复制了体感处理的结果。两组均在初级体感、楔前叶和眶额皮质中表现出检索成功。 S1 活动可能表明一般的感觉记忆过程。
Calcarine sulcal cortex possibly contributes to semantic recognition memory in early blind (EB). We assessed a recognition memory role using vibrotactile rhythms and a retrieval success paradigm involving learned “old” and “new” rhythms in EB and sighted. EB showed no activation differences in occipital cortex indicating retrieval success but replicated findings of somatosensory processing. Both groups showed retrieval success in primary somatosensory, precuneus, and orbitofrontal cortex. The S1 activity might indicate generic sensory memory processes.
