Nonassociative learning is an important property of neural organization in both vertebrate and invertebrate species. In this paper we propose a neural model for nonassociative learning in a well studied prototypical sensory-motor scheme: the landing reaction of flies. The general structure of the model consists of sensory processing stages, a sensory-motor gate network, and motor control circuits. The paper concentrates on the sensory-motor gate network which has an agonist-antagonist structure. Sensory inputs to this circuit are transduced by chemical messenger systems whose dynamics include depletion and replenishment terms. The resulting circuit is a gated dipole anatomy and we show that it gives a good account of nonassociative learning in the landing reaction of the fly.
非联合型学习是脊椎动物和无脊椎动物神经组织的一个重要特性。在本文中，我们针对一个经过充分研究的典型感觉运动模式——果蝇的着陆反应，提出了一种非联合型学习的神经模型。该模型的总体结构包括感觉处理阶段、感觉运动门控网络和运动控制电路。本文重点关注具有激动剂 - 拮抗剂结构的感觉运动门控网络。该电路的感觉输入由化学信使系统转导，其动力学包括消耗和补充项。由此产生的电路是一种门控偶极解剖结构，我们表明它能够很好地解释果蝇着陆反应中的非联合型学习。
