Ausbildung kortikaler Repräsentationen, die der langfristigen perzeptuellen Bahnung (Priming) zugrunde liegen: Die Rolle von Verarbeitungseffizienz, Aufmerksamkeit, neuronaler Selektivität und Markmalsverlust

启动是一种重要的，有时是无意识的长期记忆功能，通过这种功能，暴露于刺激物可以改善未来对该刺激物的认知处理。视觉感知启动伴随着腹侧视觉流中重复（提取）的神经反应降低，这被假设为反映了（1）增加的神经处理效率，或（2）锐化的神经反应，或（3）神经特征编码的丢失。与直觉相反的是，启动也与初始暴露（编码）时腹侧视觉流中的神经反应降低有关，这表明（4）编码和提取时与启动相关的神经反应降低可能存在不同的神经机制，（5）编码时自上而下的注意因素可能在启动的神经基础中发挥重要作用。四个实验，提出了调查这五个假设的神经基础的启动，明确操纵认知加工效率，注意力，和感知功能之间的匹配研究和测试刺激，使用多模态测量的大脑活动（功能磁共振成像，脑磁图，脑电图）在编码和检索。

Priming is an important, sometimes nonconscious, long-term memory function, by which exposure to a stimulus improves the future cognitive processing of that stimulus. Visual perceptual priming is accompanied by decreased neural responses in the ventral visual stream on repetition (retrieval) that have been hypothesized to reflect (1) increased neural processing efficiency, or (2) sharpened neural responding, or (3) loss of neural feature coding. Counterintuitively, priming has now also been linked with neural response decreases in the ventral visual stream on initial exposure (encoding), suggesting (4) that different neural mechanisms may underlie priming-related neural response decreases at encoding and at retrieval, and (5) that top-down attentional factors at encoding may play an important role in the neural basis of priming. Four experiments are proposed that investigate these five hypotheses regarding the neural basis of priming, by explicitly manipulating cognitive processing efficiency, attention, and perceptual feature match between study and test stimuli, using multi-modal measurements of brain activity (fMRI, MEG, EEG) at both encoding and retrieval.
