In this article, we explore the concept of polysemia in sensory information processing within the brain. We suggest that, just as words can have different meanings based on context, sensory inputs are interpreted differently depending on the animal's current state and behavior. Focusing on the trigeminal sensory nuclei in rats, we highlight the role of inhibitory circuits in gating sensory information and propose that sensory signals are polysemic, with their meaning influenced by emotional, hormonal, and motivational factors.
在本文中，我们探讨了大脑中感觉信息处理过程中的多义性概念。我们认为，正如单词可以根据上下文有不同含义一样，感觉输入会根据动物当前的状态和行为而被不同地解释。以大鼠的三叉神经感觉核为重点，我们强调了抑制性回路在控制感觉信息方面的作用，并提出感觉信号是多义的，其含义受情绪、激素和动机因素的影响。
