嗅觉注意数据集

人类对外界刺激的知觉，只是其大脑信息加工的部分内容，还有许多对刺激的加工没有进入个体的意识。人类嗅觉系统以其区别于其它感觉系统的解剖特性，为研究意识下信息加工提供了独特的模型。虽然前人研究发现阈下嗅觉刺激可以影响个体行为，但我们对意识下的嗅觉加工机制了解现在还并不充分。研究采用嗅觉版点探测范式，结合行为实验和功能磁共振实验，检验意识下的单鼻特异性信息是否可以被注意调节，以及这种单鼻特异性注意增益的神经表征。

Human perception of external stimuli is merely a subset of the brain's information processing, with a large amount of stimulus-related processing remaining outside conscious awareness. The human olfactory system, distinguished from other sensory systems by its unique anatomical properties, serves as a distinctive model for researching preconscious information processing. While prior studies have revealed that subliminal olfactory stimuli can modulate individual behavior, our current understanding of the mechanisms underlying preconscious olfactory processing remains insufficient. The present study adopted the olfactory version of the dot-probe paradigm, combining behavioral experiments and functional magnetic resonance imaging (fMRI) experiments, to examine whether preconscious single-nostril-specific information can be modulated by attention, as well as the neural correlates of this attention-mediated gain for single-nostril-specific information.

背景概述

该数据集聚焦于嗅觉注意机制的研究，通过双鼻孔刺激实验，揭示了注意能促进同一鼻孔内气味目标的检测，而这一过程不被意识察觉。数据集包含神经影像数据，支持对鼻孔特异性注意与大脑前顶叶注意网络关联的分析，适用于嗅觉认知和注意神经科学领域的研究。
