  withdrawal reflex
Ultrastructure of the synapses of sensory neurons that mediate the gill-withdrawal reflex inAplysia
      
Two invertebrate models of learning are considered: the gill-withdrawal reflex ofAplysia and avoidance learning inDrosophila melanogaster.
      
After BrX-537Aadministration, the latency of tail withdrawal reflex wasshortened within the 2- to 8-hr period.
      
It may be one of the loci where the CNS and peripheral nervous system (PNS) interact and form an integrated circuit to mediate gill withdrawal reflex (GWR) behaviors.
      
During the conditioning of the withdrawal reflex, the unconditioned stimulus, a tail shock, produces presynaptic facilitation of synaptic transmission from the siphon sensory neurons in the conditioned stimulus pathway.

This article summarily introduces the primary results which were obtained by Kandel et al. through investigating the habituation and sensitization of the gill withdrawal reflex in Aplysia, and reviews its significance briefly.

本文扼要介绍Kandel等研究海兔缩鳃反射习惯化和敏感化所得的主要结果,并对其意义作简要评述。

The morphological properties of serotoninergic immunoreactive fibers and their spatial relationships to pleural sensory neurons of Aplysia were studied with an immunocytochemical ABC method under light and transmission electron microscopy.The data show that 5-HT- IR varicosities make apparent synaptic contacts with pleural sensory neurons of aplysia.In light microscopy,it was observed numerous 5-HT-IR fibers containing varicosities around the somata and the initial axon segment of pleural sensory neurons.Labeled...

The morphological properties of serotoninergic immunoreactive fibers and their spatial relationships to pleural sensory neurons of Aplysia were studied with an immunocytochemical ABC method under light and transmission electron microscopy.The data show that 5-HT- IR varicosities make apparent synaptic contacts with pleural sensory neurons of aplysia.In light microscopy,it was observed numerous 5-HT-IR fibers containing varicosities around the somata and the initial axon segment of pleural sensory neurons.Labeled varicosities(n= 574)might be classfied into three groups based on their size:i.e.small(0.2~1.2 μm, 79%),medium(1.4~2.4 μm,18%),and large(>2.6 μm,3%)groups.In electron mi- croscopy,it was observed axosomatic,axoaxonic,axoglial synaptic contacts in the pleural sen- sory clusters.Two types of synaptic contacts,flat and invaginated,were found.After mea- suring the shortest diameter of the varicosity(0.1~1.0 μm,n=42),it appeared that only the small varicosities formed synaptic contacts.These results suggest that under appropriated physiological conditions,serotonin might be released from varicosities directly onto perikayra of pleural sensory neurons eliciting the cellular changes correlated with sensitization.Two types of synaptic contacts,flat and invaginatcd,could represent two different functional states,the invaginated type more effective than the other.Thus,pleural sensory neurons con- tributing to sensitization of tail withdrawal reflex in aplysia could be activated by serotonin- ergic neurons.

应用免疫细胞化学 ABC 法,研究了海兔5-羟色胺免疫反应阳性(5-HT-IR)纤维与侧节感觉神经元的空间关系。在光镜下可见5-HT-IR 纤维走向 PSN 并围绕在 PSN 胞体及轴突起始段,交织成网.5-HT-IR 膨体依据大小可分为小型、中型和大型3类。5-HT-IR 膨体与 PSN 构成轴-体和轴-轴突触.尚可见到轴-胶突触存在.各类突触可分为平坦型和内陷型.参与突触形成的膨体均为小型膨体.本文首次报道了无脊椎动物海兔神经元之间存在着轴-体突触联系,并从形态学上证明5-HT 能神经通过与 PSN 的突触联系,从而参与海兔尾回缩反射弧的组成.

In the present investigation the intensity of stimulated electro-acupuncture (EA) was measured by electrophysiological collision technique. In the behavioral experiments, by applying the weak electro-acupuncture pulses (50 Hz, 1~1. 5mA), not enough to activated Aδ afferent fibers, to Yanglingquan and Xuanzhong points, the latency of nociceptive hind limb withdrawal reflex, but not tail -flick latency was prolonged. Administered intraperitoneally, both theophylline and caffeine, P1purinergic (adenosine)...

In the present investigation the intensity of stimulated electro-acupuncture (EA) was measured by electrophysiological collision technique. In the behavioral experiments, by applying the weak electro-acupuncture pulses (50 Hz, 1~1. 5mA), not enough to activated Aδ afferent fibers, to Yanglingquan and Xuanzhong points, the latency of nociceptive hind limb withdrawal reflex, but not tail -flick latency was prolonged. Administered intraperitoneally, both theophylline and caffeine, P1purinergic (adenosine) receptor antagonists, could block the electroacupuncture-induced elevation of the nociceptive thresholds in a dose-effect related manner, whereas dipyridamole, an inhibitor of adenosine release, could shorten the after effect of electro-acupuncture in a dose dependent way.These results suggest that weak electro-acupuncture may induce analgesia and purines appear to be involved in this process

本文用电生理学逆向碰撞方法测定了兴奋穴位Aδ类传入神经纤维的模拟电针强度。用弱于此强度的脉冲(50Hz,1~1.5mA),电针大鼠“阳陵泉”和“悬钟”穴,可引起大鼠缩腿痛阈升高,但不引起甩尾痛阈升高。腹腔给予腺苷受体阻断剂茶碱和咖啡因可阻断电针效应,并呈一定的量效关系;腹腔注射腺苷释放抑制剂潘生丁可缩短电针的后效应,减弱电针效应。结果提示:弱强度电针可引起节段性的镇痛效应,其中可能有嘌呤类参与。
