Visual processing depends on rapid parsing of global features followed by analysis of fine detail. A new study suggests that this transformation is enabled by a cycle of saccades and fixational drifts, which reformat visual input to match the spatiotemporal sensitivity of fast and slow neuronal pathways.
视觉处理依赖于快速解析全局特征,然后再分析细微细节。一项新的研究表明,这种转变是通过扫视和注视漂移的循环实现的,扫视和注视漂移重新格式化视觉输入,以匹配快速和慢速神经元通路的时空敏感性。
