abstract：:Morphine remains widely used in clinical settings due to its potent analgesic properties. However, one of the gravest risks of all opioids is their ability to induce respiratory depression and subsequent brain hypoxia that can lead to coma and death. Due to these life-threatening effects, our goal was to examine the e...

abstract：:Phasic and tonic motor neurons of crustaceans differ strikingly in their junctional synaptic physiology. Tonic neurons generally produce small excitatory postsynaptic potentials (EPSPs) that facilitate strongly as stimulation frequency is increased, and normally show no synaptic depression. In contrast, phasic neurons...
