背景情况:
- 旧世界 (OW) 和新世界 (NW) 葡萄酒的感觉特征在历史上是不同的.
- 调查这些形状的变化随着时间的推移对于理解不断变化的葡萄酒特征和消费者偏好至关重要.
研究的目的:
- 为了确定OW和NW葡萄酒在1997-2001年和2014-2018年之间在感官特征上是否趋同或分歧.
- 评估酒精含量对潜在感官变化的影响.
主要方法:
- 对来自OW和NW地区的31种葡萄酒的专家葡萄酒评论家描述符的分析,跨越两个不同的5年时期 (1997-2001年和2014-2018年).
- 描述符的频率计数,奇平方测试和对应分析 (CA) 来比较感官配置文件.
- 双向ANOVA分析区域和时间段之间酒精 (乙醇) 含量的显著差异.
主要成果:

Introduction to Special Senses
5.5K
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...

Introduction to Sensory Receptors
3.1K
Sensory receptors are vital in our ability to perceive and interpret the world. Sensory receptors are specialized cells in the peripheral nervous system that respond to various stimuli and enable one to experience different sensations. Based on specific criteria, sensory receptors are classified into distinct types.
The first classification criterion is based on cell type, position, and function. Some receptor cells are neurons with free nerve endings, where their dendrites are embedded in the...

Gustation
47.6K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

Somatosensation
36.4K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Taste Buds and Receptors
1.9K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Sensory Perception: Organization of the Somatosensory System
2.8K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...
