一个杰出的口腔:在加西亚效应期间的味道歧视和决策在池牛Lymnaea stagnalis中
1Hotchkiss Brain Institute, University of Calgary, Calgary, AB, T2N 1N4, Canada.
概括
在Lymnaea stagnalis中的加西亚效应表明基于新奇的味道厌恶. 牛可以从混合物中区分新鲜的单独食物,对每种食物都显示出独特的记忆,而不会改变偏好.

背景情况:
- 加西亚效应是一种有条件的味觉厌恶形式,需要一种新鲜的味道和随后的疾病状态.
- 这种效应之前已经在池牛 Lymnaea stagnalis.中被证明.
研究的目的:
- 调查新奇性在Lymnaea stagnalis.味道歧视和记忆中的作用.
- 为了确定牛是否能区分单个食物物质 (胡卜,甜菜) 和混合物 (Mélange).
- 评估加西亚效应对混合品味的影响是否会改变其单个成分的价值.
主要方法:
- 利用加西亚效应的新性要求来测试Lymnaea stagnalis的感官歧视.

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,...

The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

330
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...
