principally) two types of voltage-activated Ca2+ chan- nels (VACCs) - a functionally-distinct isoformof As in many other types of neuron, two classes of Ca2+-dependent K+ chan- nels can be 2/150)K (Figure 5) and small-conductance ("SK") channels, of conductance ~ 2 pS in Calcium...
It is suggested that α 2 -adrenoceptors mediate the inhibition of voltage-dependent Ca 2+ entry during the action potential. 展开 关键词: Parasympathetic neuron Calcium-dependent action potential Norepinephrine α 2-Adrenoceptor Inhibition DOI: 10.1016/0168-0102(88)90022-3 ...

For example, hippocampal neurons respond to the local application of ACPD by generating a Ca2+ wave that spreads through the neuron, which then becomes refractory to further stimulation (Jaffe and Brown 1994). However, the cell can be reprimed by at least three bursts of action potentials ...

We found that axotomy reduced the amplitude and duration of the afterhyperpolarization (AHP) of the action potential (AP) of bullfrog sympathetic neurones. In addition, the repolarization of the AP was slowed. The Ca 2+-channel blocker, Cd 2+ (200 μM) produced similar effects in normal ...
The depolarizing voltage response of a postsynaptic neuron to a neurotransmitter released by one or more afferent presynaptic terminals that moves the membrane potential towards the action potential threshold. Electrotonic signal A passively propagating electrical impulse. It differs from an action potential...
