概括
年轻的羊可以检测到人体气味,并对陌生的气味做出反应. 然而,它们并没有特别区分压力和非压力的人类气味,这表明在绵羊中通过嗅觉传染的情感传染有限.
科学领域:
- 动物行为 动物行为
- 嗅觉感知是一种嗅觉感知.
- 人与动物的互动
背景情况:
- 羊 (Ovis aries) 可以通过视觉和声音信号感知人类的情绪.
- 绵羊检测和解释人体气味的能力,特别是与情绪状态相关的能力,还不太清楚.
研究的目的:
- 为了调查羊是否能检测到人体气味.
- 为了确定羊是否可以通过嗅觉来区分压力和非压力个体的气味.
- 观察羊对人类情感气味的反应行为.
主要方法:
- 在压力 (口头考试) 和非压力 (常规课堂) 条件下从学生身上收集下分泌物.
- 习惯-脱习程序使羔羊暴露于收集的人类气味.
- 行为反应的分析,包括空间性,接近/撤退,耳朵定位,嗅觉,摄入和发声.
主要成果:
- 羊羔表现出行为变化,如改变耳朵定位和接近行为,当暴露于一种新闻的气味 (失常刺激).
- 绵羊表现出一些区分习惯和不习惯气味的迹象.
- 没有观察到基于人类气味的压力或非压力值的特定行为歧视.
结论:
- 年轻的羊可以检测到人体气味.
- 绵羊对不熟悉的人类气味做出反应,但不会表现出与压力水平相关的特定歧视.
- 需要进一步的研究才能充分理解人与羊的嗅觉沟通和关系.

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.

Communication
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.
Introduction to Special Senses
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive functions.
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...
Physiology of Smell and Olfactory Pathway
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
