Post‐ and presynaptic effects of norepinephrine in guinea‐pig colonic submucous plexusalpha-adrenoreceptorsdistal colonnorepinephrinesIPSPsubmucous plexusIntracellular recording techniques were used to investigate the effects of norepinephrine on submucous neurones in the guinea-pig distal colon. In 81% of...
Which neurotransmitter is found at both the neuromuscular junction and the post ganglionic (post-synaptic) neuron of the parasympathetic branch? When the action potential reaches the synaptic terminal, the uptake of what ion stimulates the movement of synaptic vesicles to the p...
Answer and Explanation:1 The correct answer is(b): terminal ganglia. Ganglia are structures that contain peripheral neuron cell bodies. Terminal ganglia are the ganglia that...

We found that postweaning social isolation caused a decrease of in vivo firing activity of MeAp neurons, and reduced drive from excitatory afferents. In vitro electrophysiological studies found that postweaning social isolation caused a presynaptic impairment of excitatory input to the dorsal MeAp, but...
Amantadine is believed to increase wakefulness through increasing dopamine (DA) synthesis and blocking reuptake, therefore increasing the amount of DA available to bind to receptors on the postsynaptic neuron [9]. The drug may have antagonistic effects at the N-methyl-D-aspartate receptor, acting ...
These neurons map in the Abg and show extensive presynaptic arborisations within the posterior brain (Figure 2). Furthermore, two descending fibers of the dsx-Abg neurons were found to directly innervate specific areas of the reproductive system, e.g. the uterus (Figure 2). They might ...

Furthermore, the crucial role of estrogens in making serotonin available, by inhibiting the degradation of serotonin through the activation of monoamine oxidase (MO) and the reuptake of serotonin from the synaptic cleft to the presynaptic neuron, is also a widely confirmed mechanism [113,114,115,...
