概括

中国修改的嗅觉识别 (CMOI) 测试通过使用熟悉的气味和干扰物来提高嗅觉识别的准确性. 这种增强的测试减少了不熟悉的气味引起的错误,使其更适合中国人群.

科学领域:

嗅觉神经科学是一种神经科学.
心理测量心理测量心理测量
认知测试的跨文化适应

背景情况:

嗅探棒嗅觉识别 (SSOI) 测试是评估嗅觉功能的广泛使用的工具.
气味感知和熟悉度的文化特异性可能会影响标准化测试的有效性.
调整嗅觉测试对于在不同人群中进行准确评估至关重要.

研究的目的:

开发和验证中国修改嗅觉识别 (CMOI) 测试.
通过将中国人口文化上熟悉的气味和分心因素纳入SSOI测试来增强SSOI测试.
提高中国嗅觉识别测试的准确性和可靠性.

主要方法:

招募了200名健康的中国志愿者进行气味熟悉度评级和测试管理.
对100名志愿者进行了一项调查,以评估他们对121种气味的熟悉程度.
根据熟悉度等级修改了SSOI测试,创建了修改的干扰器嗅觉识别 (MDOI) 和CMOI测试.
对100名志愿者进行SSOI,MDOI和CMOI测试,并比较他们的表现.

主要成果:

在SSOI测试中确定了31个不熟悉的气味描述和23个低熟悉度的分心因素.
用更熟悉的物品取代不熟悉的物品,导致MDOI和CMOI测试.
CMOI测试得分明显高于SSOI和MDOI (p < 0.0001).这些测试得分明显高于SSOI和MDOI (p < 0.0001).
在CMOI中,正确识别率明显高于SSOI (p < 0.01).

结论:

与现有版本相比,CMOI测试显著提高了嗅觉识别得分.
修改后的测试有效地减轻了因不熟悉的气味和干扰因素引起的错误.
CMOI测试是中国人口嗅觉识别的文化适应和更准确的工具.

Olfaction

Olfaction

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Olfactory Receptors: Location and Structure

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
