Repeated stimulus processing is often associated with a reduction in neural activity, as measured by single-cell recording or by haemodynamic imaging techniques like PET and fMRI. These reductions are sometimes linked to the behavioural phenomenon of priming. In this article, we discuss issues relevant to theories that attempt to relate these phenomena, concentrating in particular on the interpretative limitations of current imaging techniques.
重复刺激处理通常与神经活动的减少有关，这是通过单细胞记录或诸如正电子发射断层扫描（PET）和功能磁共振成像（fMRI）等血液动力学成像技术来测量的。这些减少有时与启动的行为现象有关。在本文中，我们讨论了与试图关联这些现象的理论相关的问题，特别关注当前成像技术的解释局限性。
