The system of ionic currents that controls action potential shape and firing patterns in central neurons, although complex, has remarkable advantages for pursuing general problems in systems biology (such as robustness and redundancy): it has highly quantifiable elements, which are well-suited to mathe...
Average action potential and corresponding magnetic signals. (A) Result of triggering on nine consecutive APs from a trap lobe heated to 41 °C, then averaging the electric and magnetic data from a 4.5 s window around each trigger point. The average magnetic traces (bottom graph, opaque traces...
No alterations in the magnitude and voltage dependence of inward rectifier ( I Kl ) were found around the resting membrane potential. The diabetes-related suppression of I to explains the decreased repolarization rate of action potentials. 展开 ...
resting potential, the imbalance ofelectrical chargethat exists between the interior of electrically excitableneurons(nerve cells) and their surroundings. The resting potential of electrically excitablecellslies in the range of −60 to −95 millivolts (1 millivolt = 0.001volt), with the inside ...

Das Membranpotenzial in Neuronen Neuronen haben typischerweise ein Ruhemembranpotential von etwa- 70 Millivolt (mV). Wenn sie Signale, z.B. von Neurotransmittern oder Sinnesreizen, empfangen, kann ihr Membranpotential je nach Art des Reizes hyperpolarisieren (negativer werden) oder depolarisie...
