Using functional MRI (fMRI) and a sophisticated forward encoding and decoding approach across the cortical surface, a new study examines how attention alternates tuning functions across a large set of semantic categories. The results suggest a dynamic attention mechanism that allocates greater resources to the attended and related semantic categories at the expense of unattended ones.
使用功能磁共振成像（fMRI）和一种复杂的皮质表面前向编码和解码方法，一项新的研究检查了注意力如何在一大类语义类别之间交替调整调谐功能。研究结果表明，存在一种动态注意力机制，该机制以牺牲未被注意的语义类别为代价，为被注意和相关的语义类别分配更多的资源。
