appears to make no difference to the rate of recovery of bladder accommodation, sensation and contractility, although rapid decompression results in a greater degree of ocdema, congestion and bleeding from the bladder than if it is done slowly. The recovery of bladder function post-operatively has only been investigated in patients who presented with paradoxical incontinence. It would be intere...
متن کاملCalcium and transmitter release.
The mechanism of transmitter release by intracellular Ca has been explored by recording presynaptic Ca concentration ([Ca2+]i) with Ca-sensitive fluorescent dyes and by controlling [Ca2+]i with photosensitive Ca chelators. [Ca2+]i decays slowly (in seconds) after presynaptic action potentials, while transmitter release lasts only a few ms after each spike at fast synapses. Simulations of Ca dif...
متن کاملQuantitative Aspects of Transmitter Release
The opener-stretcher motor neuron in crayfish makes 50 endings upon each of 1200 muscle fibers. We have calculated the quantal content of junctional potentials produced by individual terminals and by the whole cell at various physiological frequencies. The results show that when the motor neuron is active at 20 impulses/second, it releases 50 quanta/impulse per muscle fiber, or a total of 4.5 x...

متن کاملEpisodic ataxia type 1 mutations differentially affect neuronal excitability and transmitter release.
Heterozygous mutations of KCNA1, the gene encoding potassium channel Kv1.1 subunits, cause episodic ataxia type 1 (EA1), which is characterized by paroxysmal cerebellar incoordination and interictal myokymia. Some mutations are also associated with epilepsy. Although Kv1.1-containing potassium channels play important roles in neuronal excitability and neurotransmitter release, it is not known h...
